The crown jewel of any climbing career, Everest is a transformative peak that is guaranteed to not just challenge you, but to change you.
Highlights:
- Discover what you are truly capable of
- Stand on the highest point of our planet.
- Experience the deep humility that climbing in the Himalaya evokes
- Enjoy lifelong friendships with your Sherpa and fellow climbers alike
Choosing the Right Option
Choosing the right service level is a decision based on your experience, desire for more supervision/personal attention or autonomy and that meets your budget can be tricky.
Essentially the greater level of experience you have, the more autonomy you can enjoy at a lower price point. As the level of Guidance increases, naturally so does the cost.
Here’s a good way to start:
Allowing you to customize your expedition to suit your needs is a huge priority for us.
As mountaineers ourselves we understand that it’s the little things that can make the difference. Comfortable, well rested climbers are successful climbers.
Whilst people often dismiss these Add On’s as indulgent luxuries, for many it’s Therefore we encourage you to tailor your expedition and talk to us about any other options you may wish for.
Nothing found.
CTSS prides itself on offering the best expedition at the best price and offering the best amenities that many of our competitors don’t. Scroll through the photos above to view our base camp set up.

- A cappuccino machine with barista and cafe sitting area
- State-of-the-art oxygen systems to maximize your summit chances. Our oxygen system weight 4.5kg total as opposed to the much larger American oxygen system that weighs 8.5kg that some companies use. This 4kg/9lb difference make a
- HUGE difference on summit day when every ounce counts.
- The best weather forecasts money can buy sent to us daily to make sure you get the right weather window. Expedition leader Mike Hamill has been interpreting these forecasts for decades to great success.
- Unlimited 3rd party wifi for purchase at base camp.

How early should I commit to my climb?
We feel that the sooner you commit the better as it gives you more time to prepare mentally and physically for the climb. Climbing Everest is a huge undertaking and something that you will want to work up to consistently. I have found that people are generally more successful when they commit earlier as it gives them longer to shake out any problems that may arise, arrange their home and work life to be away for a number of months, and build their fitness endurance and strength up over time and thereby avoid injury etc.
What’s the best climb to prepare for Everest?
Hands down I think that Cho Oyu is the best, most specific Everest prep. You get an understanding of how your body does at altitudes over 8000m and get familiar with the oxygen system and climbing with the Sherpa.
Will I need to purchase insurance?
Yes, trip insurance is required for this program and it needs to cover the entire cost of the trip and include trip cancellation, trip interruption, medical expenses, repatriation, and evacuation for the entire length of the expedition.
Trekkers are required to have the same coverage. Unforeseen hiccups are part of adventure travel both before and during the expedition and it can be very expensive. Every effort should be taken to account for them in advance. Please forward a copy of your insurance for our records so that we can help you in the event that it need to be used during the expedition. Most insurers require us to contact them immediately.
For more information on trip insurance please visit the “Trip Insurance” page on the website.
Why do you choose to climb from the south side?
I prefer the South side of Everest for a number of reasons. While people think avoiding the icefall means a safer climb, I beg to differ. The South side has a lot more infrastructure which means there are more assurances including helicopter access, the HRA (Himalayan Rescue Association) medical clinic manned with speciality trained doctors 24/7 at base camp. If something goes wrong, we have much higher chances of evacuating you and getting you to a hospital in Kathmandu within hours, whereas if something were to go wrong on the North Side, it could take days for a rescue and evacuation to be completed and to get you to the nearest hospital. The North side is also a more hostile environment being windier, drier and dustier. Further, the border to Tibet has often been closed to climbers on very short notice over the last 10 years.
What program upgrades are available?
The main add-ons for the Everest programs are extra oxygen, the Everest Executive Option (upgraded tent accommodation, single supplement etc) single rooms upgrades and/or deluxe rooms in the trekking lodges. If you are climbing Everest you may choose to add on an ascent of Lhotse. Please discuss these add-ons with us and we can help you decide if they are right for you.
It’s a long time away from home – can my family and friends join me?
Yes, your family and friends are more than welcome to join us on the trek in to base camp and even climb Lobuche peak if they like. (Our standard treks stay a 2 nights in Base Camp before departing but we have had people stay longer and this can be arranged by chatting to us directly) Please let us know immediately if you have people who want to join us so that we can make arrangements for them. Space in hotels in Kathmandu and in the teahouses is limited during climbing season so we need to know final numbers asap!
What’s the deal with extra oxygen?
We give you plenty of oxygen to run a comfortable oxygen flow (3L/min or so) throughout the climb. As standard we give you 10 bottles (7 for your and 3 for your Sherpa). If you would like extra oxygen we encourage your decision and are happy to arrange an additional 3 bottles. With the extra Os you can run high flow (4 – 5L/min) throughout summit day, start oxygen at Camp 2, and have a bit extra in case of delays at the South Col etc. Extra oxygen can help keep you warmer and moving faster so it’s a great safety margin. You certainly don’t need the extra oxygen but I’ve always seen it as a good on-mountain insurance policy as such.
Will we be taught how to use the oxygen systems?
Top quality, reliable oxygen tanks, masks and regulators will be provided for you on your climb and we will go through their usage in depth at base camp so you can practice before your climb. We typically use oxygen from Camp 3 (roughly 24,500ft) to sleep & climb on to the summit. If you are interested in extra oxygen to use from C2 (roughly 23,000ft) on the summit bid and to run a higher flow rate on summit day please let us know in advance and we can arrange this.
What’s the acclimatization process?
Our entire expedition including the trip to base camp is slow in order to allow our bodies ample time to acclimate. In the Khumbu, we gaining altitude quickly and this slow process will allow us to acclimate properly and avoid altitude sickness. That means there is plenty of down time while your body adjusts. Please bring a few books or movies on your devices and be patient. This is a slow process but it will give you a much better chance at success on the climb and trek. Make sure to communicate with your guides directly if you are experiencing any altitude issues.
How much cash should I bring?
It is better to have more money than you need than not enough, while most things are covered on the trip once you land in Kathmandu (check what’s included/what’s not included list for details) you will still need cash. The cash that you need to bring includes money for visas ($100 for 1 single entry 90 day), Sherpa tip pool ($600 for climbers and $300 for trekkers), money for staff tips (customary but optional) $200 for potential consultation and treatment by the doctors at base camp, $500 to cover expenses for a potential early departure (not often, but sometimes this occurs) and $1,500 – $5,000 if you think you’ll want a helicopter ride out, $300 for miscellaneous expenses like non-group meals, shopping, drinks around Kathmandu and while on the trip to base camp if you want wifi, sodas, specialty coffees, bottled water, charging of devices or snacks (meals are covered), Generally we recommend bringing $2,000 – $3,000 USD plus a credit card to cover all potential expenses including an early departure but it is unlikely that you will need all of this. Small denominations (1’s, 5’s, 10’s and 20’s) are better and although American dollars are accepted, you can change money into Nepali rupees at change houses when you arrive. Rates are generally about the same and I’ve never encountered one that isn’t legitimate. Also, there are now quite a few ATM’s around town where you can use your card to take out local cash at a good rate. It is much more difficult to change money, especially large sums, once in the Khumbu Valley. Please let your credit card company know you will be traveling so you can use your card (and not set off the fraud alert due to using the card in a foreign country)
How much gear can I bring?
We pay for yak + porter transport for two 50lb duffels (1x trekking duffel which will travel with you and 1x climbing duffel which will go straight to base camp) this should be more than enough weight. If you want toto bring more than this with you, you will be expected to pay for the excess weight. This amount will include excess on the flight to Lukla and then be roughly $300/duffel each way to base camp beyond the two duffel allotments. Transport is getting more expensive every year so please leave the kitchen sink at home! (we already have those at base camp) Just bring what you need to be comfortable but not more than that.
What immunizations do I need?
Make sure your immunizations are up to date. Consult your doctor, local travel clinic, or the Centers for Disease Control (CDC) for updated information on immunizations for Nepal and China. Recommended immunizations include diphtheria-tetanus (DPT), polio, mumps-measles-rubella (MMR), meningitis, hepatitis A and B, cholera and typhoid, and rabies. Malaria shouldn’t be a problem in Kathmandu or on the climb. If you plan to travel to lower-elevation areas in Nepal before or after the climb, you should consider malaria chemoprophylaxis.
How should I pack?
For the trip to base camp climbers will need to pack in two separate duffels: a base camp duffel and a trekking duffel. Climber’s base camp duffel will not be accessible while on the trek to Lobuche en route to base camp and should contain all of your climbing gear (crampons, axes, down suit etc) and items you won’t need until Lobuche. Your trekking duffel will contain everything you will need for the trip to base camp including your trekking gear, rain gear, street clothes, and a light sleeping bag. Trekkers will have everything with them in one duffel. Please keep everything you will need with you such as medications and medical supplies. What will go in your trekking and base camp duffels will be covered in more detail in Kathmandu. Pack an additional small lightweight duffel in your luggage to leave street, travel clothes and things you won’t need on the expedition at the hotel in Kathmandu
What is the food like on the climb?
At Base Camp CTSS has the best chefs and food, hands down. Our teams are consistently blown away by the quality of food and hygiene at base camp considering where we are in the world. Our head chef trains at 5 star restaurants during the off season. Think lemon crepes, cheese omelettes, chicken cordon bleu, pizza, fresh fruit almost daily, fresh salads, steaks, apple pie, fresh croissants and cinnamon rolls, and moist chocolate cake. We get shipments of fresh meat, fruit, vegetable, and other supplies weekly. Dave Hahn, non-Sherpa Everest summit record holder with 15 summits said about our head chef Kumar, “A real pro. Kumar is the reason I kept climbing in the Himalayas as long as I did.”
Why do I need to bring my own snacks?
We do a big Costco run for group snack and meal food for the mountain and will have lots of good stuff but we want to make sure everyone has the food that they need. Even people who aren’t usually picky about food can get really particular about what they can digest on Everest due to the extreme altitude and getting lots of calories is hugely important. Gu packs, shot blocks, nuts, Snickers bars, cheese, etc… whatever it is that you know you can eat when you don’t want to eat anything is best. Getting speciality and familiar food can be difficult in Nepal so it’s best you bring what you love from home. Also, bring a good supply of cough drops or hard candy as you might like them in the dry air. We’ll have some for the team but people seem to go through them really quickly.
How safe is the food and water?
As in Kathmandu, once on the trail in to base camp it is highly recommended that you stick to treated rather than tap water. Properly boiled water is available in all the teahouses and bottled water is readily available in stores en route but to reduce the amount of trash and pollution in the valley we encourage you buying boiled or UV treated water from teahouses. You can also bring your own water treatment solution. We will provide some teas and coffees at meal times but if you want sodas, bottled waters, specialty coffees, or drinks outside of meal times we ask that you purchase them yourself. Nepal isn’t known for its cuisine. The food on the trek to base camp can become a bit monotonous but it’s energy dense and fufilling. Asian inspired, there is a lot of fried rice, rice based meals, soups, omlettes etc. Stick to meals where the food is obviously local and sourced from the valley. We stay in reputable teahouses who have a good understanding of food hygiene so our climbers and trekkers rarely get sick. It’s ok and somewhat expected to get a slightly upset tummy as you’ll be eating food that is different to what you are used to. At Base Camp, we have our own chefs who are incredible and take every precaution, in a full catering kitchen. They also cook Western foods, have fresh food including fruit, vegetables and meat resupplied regularly and serve a good variety. CTSS is known to have the best food on the mountain and given where in the world we are, that’s a remarkable feat.
What’s the accommodation at Base Camp like?
We use North Face VE-25 tents. They’re large, spacious (the same size as a 3 man tent) and extremely high quality. Inside you will have a thick, comfortable 15cm sleeping mattress and a pillow. This is placed on top of a ground cloth to keep out the wet and cold. We do offer a heated double roomed tent under our Everest executive program. To avoid you overcrowding your tent, there is a separate gear tent where you may store your climbing equipment.
Will I be sharing a tent?
No, for the majority of the climb you are not sharing a tent. We stay at the famous “Yak and Yeti” hotel in Kathmandu and in the finest teahouses while trekking to base camp. While at Everest base camp you will have your own tent to spread your gear out and call home. There will be times on the mountain where you will need to share a tent with another climber to reduce the number of dangerous loads the Sherpa need to carry through the treacherous Khumbu Ice fall. It’s also a lot warmer and safer when you can keep an eye on each other.
What about phones & wifi?
We understand it’s important to stay in touch with friends and family and on top of your inbox. There are a number of ways to do this;
We suggest picking up a local Ncell sim card in Kathmandu with a data package. Signal is reliable in Kathmandu & for most of the trek up the Khumbu valley it is strong enough to support both calls and data. Once you get to base camp cell service becomes unreliable, although it can sometimes pick up a low signal (not enough to support data). You can buy a local Ncell sim card in Kathmandu and there is a Ncell store close to our hotel that we are happy to show. Your phone will need to be unlocked and you will need your passport to get a sim card. You can get recharge cards almost anywhere. This is by far the most affordable way of staying connected and getting data in the Khumbu valley up until base camp. If you’d like to use your own sim card, talk to your provider about activating your international roaming and you should be able to tie into the local networks. At base camp, when the cell service runs out, you can connect to the wifi network and make calls on facetime, Whatsapp, FB, or Skype. It is available for individual purchase which means you only pay for what you use. Please note, this is operated by a third party and we have no control over whether it works or the expense. There are also internet cafes in the bigger towns along the route to base camp to get online and third-party wifi available for purchase in most of the teahouses. Please keep devices like laptops, smartphones and iPads waterproofed in your trekking packs so they don’t break in your duffels. You will be responsible for your own valuables. There will be a satellite phone with the team but we don’t expect to use it until above base camp. It can be made available to team members at $3/minute. If you plan on bringing your own satellite phone with you, you are required to register it with Nepal which costs thousands of dollars. Should you choose not to register it and use it anyway, you do so at your own risk.
How heavy will my pack be?
In general, climbing packs on Mt. Everest are relatively light. You will likely be carrying 15lbs – 30lbs (7kg – 12kg) most of the time while climbing and less on the trek into base camp. While climbing you should be prepared to carry your gear for the day and some of your personal gear for the mountain. Sherpa will carry all of the group gear and help with personal gear where possible.
How do I charge my devices?
Given the local expense of electricity, teahouses charge you to repower and recharge your electronic devices en route to base camp. This tends to get more expensive up the valley and a portable battery pack is a good idea. You will need to bring an adapter. This cost is your own expense. Once at Base Camp we will have power and power cords that fit North American plugs. Charging is dependent upon the sun or fuel for the generator so it won’t be available all the time but we will try to make it available enough to meet your need.
I’d like my own room in hotels & teahouses…
All hotels and teahouses are double or triple occupancy but once we get to base camp you will have your own tent to spread out in. If you want single rooms en route to base camp, we can arrange this at an additional cost. Sometimes teahouses are full during the climbing season and may not have room to accommodate single rooms so please let us know as early as possible for the best chance of us securing a private room. Again this is adventure travel and we ask you to roll with the punches if they are not available.
Do I need a visa? How do I navigate Kathmandu airport arrivals?
Often just getting to Nepal can be the hardest part. Once you’re on the ground it’s time to relax. Upon exiting the plane walk to the left of the customs area and have your passport, photo, money, and visa form handy. You must pay for your visa first at the desk straight ahead and to the left before getting in the “Visa Upon Entry” line (far left of the large room). Purchase the a 90 day for Everest and Lhotse climbers or the 30 day visa for trekkers and Lobuche climbers single entry Nepali visa.
http://www.nepalimmigration.gov.np/page/visa-on-arrival
In the Khumbu, what’s not included?
We cover almost everything in the cost of the trip once we fly into the Khumbu valley so there shouldn’t be too many other expenses that you need to worry about. The biggest expense is tips. The Sherpa tip pool is $600 and I will collect that at the beginning on the climb to disperse amongst the entire team at the end of the climb including cook staff and dining staff. People sometimes tip their individual summit Sherpa a bit more than this and it seems like people have been tipping their guide about 1k-2k on the Western Guided option. The other personal expenses people accrue are wifi (through third party operators) additional personal snacks, drinking, charging of devices & toilet paper. We suggest you bring a portable charger and pack a few additional rolls of toilet paper for the trek in.
What if we can’t get into Lukla in time because of weather?
It’s good to remember that we are in the Himalaya and weather can be variable so it’s important to be patient. Generally, it’s no more than a day or two delay. If it looks like we’ll be unable to get in on the plane then we’ll look at hiring helicopters to get into a safe spot in the valley to stay on schedule.
What’s the deal with blog updates?
We know family and friends will want to follow your progress so we will be posting regular updates to the Climbing the Seven Summits blog here: https://climbingthesevensummits.com/blog/ We try to update it as often as possible but make sure your loved ones know that ‘no news is good news’. If a few days pass between updates it doesn’t mean that anything is wrong, simply that we are probably busy climbing.
We also offer partial climbs to build your Himalayan experience or have friends and family join you on your Mt. Everest expedition. These stand-alone options allow new members to join our Everest team for various parts of the expedition for instance joining us on the trek into Base Camp, our Lobuche climb, tackling the famous Khumbu Icefall up to either Camp 2 or Camp 3, or even climbing the world’s 4th tallest mountain in the world, Lhotse.

Testimonials
CTSS is a class act! The team and facilities are world class. Every detail of the expedition was perfect. Mike’s decision making, Tendi’s guidance, the strength of our Sherpa team and the food Kumar was producing were second to none. You only had to see the look on the faces of team members from other operators…to know we had something special. I can’t wait to climb with CTSS again.Peter W
After doing research on the various Everest mountaineering guide companies, I could find no reason to use anyone other than Climbing The Seven Summits. Now that I’ve returned from a successful summit of Mt. Everest with CTSS, I would highly recommend them to any climber, for any summit in the world. CTSS provides an unparalleled level of guide expertise, and very experienced Sherpa support staff, as well as exceptional accommodations and sustenance. All of this, at very competitive pricing, with different levels of service available, depending on the climber’s experience. Mike Hamill has the highest level of integrity and mountaineering expertise, constantly adapting to the needs of the team members, as well as the changes on the mountain. CTSS has significantly raised the bar in the mountaineering world – and all the other companies know it.William B, (USA)
“I had the pleasure of being guided by Tendi Sherpa, the most humble and respected individual on Mt. Everest. Tendi is famous in Nepal and widely regarded as one of the top three Sherpa. I have never met a more positive individual in my life, his laugh and smile are a permanent smile from Kathmandu airport to the roof of the world and back. During the 6 weeks we spent climbing together, he never once overlooked a clip, anchor or footstep. I can confidently say there is no safer way of climbing the tallest mountain in the world than by having Tendi by your side. With twelve Everest summits and perfect english, Tendi is like a Western guide on steroids. My favourite analogy was when I was told ‘Tendi could climb faster without oxygen and with me on his back, than I could running 6 litres per minute of oxygen” And it’s true! If you are going to take the time to climb Everest there’s no better way to stack the odds in your favour than climbing with Tendi Sherpa as your guide”Mat Wood – Dual Everest and Lhotse summiteer in under 24 hours
Tendi Sherpa – a truly amazing person and an inspirational leader… It is plain to see that the leaders of the other guiding companies hold him in the highest regard. As a client that gives you great confidence in your leader’s decision making. It was that decision making that made it such a successful trip. Thank you Tendi.Richard W
Kind, inspiring, courteous, strong and always smiling. There are truly no words I can write that do him justice. I look forward to more climbs with Tendi in the future.Peter W
Australian Alpine Academy – An Introduction to Mountaineering
Australian Alpine AcademyDifficulty Level: Beginner
The Snowy Mountains in NSW Australia is one of the most unique alpine environments in the world. The landscape itself is defined by gumtrees, wildflowers and limestone gorges and is home to Australia’s largest mainland peak, Mt Kosciuszko. The topography of Kosciuszko National Park makes for rugged and challenging environment that is perfectly suited to learning technical alpine skills. The Australian Alpine Academy focuses on teaching the fundamentals of mountaineering and backcountry travel to prepare for bigger, more technical objectives aboard.
The CTSS Australian Alpine Academy offers two in-depth programs. Choose from our ‘Introduction to Mountaineering – Alpine Academy’ which prepares you for bigger, international peaks or our ‘Winter Ascent of Kosciuszko’ as part of the Seven Summits, or combine them together for a-once-in-a-lifetime Australian winter experience.
Learn why we love climbing and mountaineering in the Snowy Mountains in our blog post Australia’s Mount Kosciuszko: An Unexpected Mountaineering Destination.

Welcome to “Climbing the Seven Summits” Australian Alpine Academy.
We are delighted to host this unique ‘Introduction to Mountaineering’ course in the Australian Alps in the hope of introducing a new generation of climbers to the joy of the mountains and equip them with a solid foundation of skill and knowledge to allow them to progress onto higher peaks.
As an adopted Aussie, I spend much of my year in Australia and I’ve come to love its unique environment. As an American I’ve grown up climbing on some of the most rugged peaks in the world; from Rainier in the North Cascades to Denali in the Alaskan Range and would have previously dismissed any alpine terrain in Australia.
Yet I’m impressed with the diversity of the terrain in the backcountry and have found it to be an excellent, uncrowded playground perfect for challenging any aspiring climber and laying down the fundamentals of big mountain climbing.
I’m excited to introduce you to this program, and look forward to meeting you in the mountains.
Best regards,
Mike Hamill

Carstensz Pyramid
Carstensz Pyramid (helicopter in and out)
Difficulty Level: Intermediate to Advanced
It is often argued as to which mountain is the true Seventh Summit: Carstensz or Kosciuszko? To that we answer, “It doesn’t matter! They are both beautiful and unique adventures in their own right so why not do them both?” In fact, it seems that many people are concluding just that and climbing both peaks.
Carstensz Pyramid is one of the world’s great adventures. Few people have the opportunity to go to such an exotic location as Irian Jaya. The fact that Carstensz is a stunning climb and one of the Seven Summits is just the icing on the cake. If you are looking for a true adventure and world-class rock climbing, look no further than Carstensz Pyramid. One of the most attractive features of the Seven Summits is that to climb them you are forced to travel the world and experience cultures you would otherwise miss. This isn’t more true for any peak than Carstensz Pyramid.



- End your expedition by meeting up with friend and family in Bali, Indonesia, a world-famous beach resort island that we usually fly through both on the way in and out of our climb
- Climb a classic rock route and brave the airy cable bridge traverse en route to the summit of Carstensz
- See a part of the world on the remote island of New Guinea that few people have seen
- Fly in a helicopter over the lush rainforest and mountains of the Sudirman Range from our start point in Timika en route to Carstensz base camp
Ready to learn more about Carstensz Pyramid? Check out our guide tips, resources, and answers to your most pressing questions in our Carstensz Top Five or check out this Climber’s Guide!
Deep in the heart of the Sudirman Range in the western central highlands of Irian Jaya lies Carstensz Pyramid. Irian Jaya comprises the western side of the island of New Guinea; the eastern part is Papua New Guinea. Irian Jaya (formerly West New Guinea or Dutch New Guinea) is part of Indonesia, a nation of more than 17,000 islands in the southern Southeast Asia. The bare, rocky, and near-vertical slopes of Carstensz Pyramid rise above the lush jungle environment and small settlements that characterize the moderately large island of New Guinea. Carstensz Pyramid is also known as Puncak Jaya in Indonesian.
Carstensz looms over the smaller peaks in the mountain range at a height of 16,024 feet (4884m). The mountain is part of the Lorentz National Park, the largest protected area is Southeast Asia. It is surrounded to the south by settlements belonging to several native Indonesian tribes, including the Dani, who live mainly in simple structures and maintain a more primitive way of life than any culture experienced on the other Seven Summits. The local culture is part of what makes a climb of Carstensz Pyramid such a unique and adventurous experience.
Carstensz is one of the least climbed of the Seven Summits because of its logistical challenges, the prohibitive expense required, and its dubious status on the Seven Summits list, although more climbers are beginning to attempt the peak as awareness of the mountain and region grow. Carstensz is a very remote mountain that lies in an exotic, undeveloped region of the world.
Welcome to CTSS’s Carstensz Pyramid Expedition!
Climbing Carstensz Pyramid is truly a once in a lifetime opportunity. This is your chance to get way off the beaten path and see a remote part of Southeast Asia that few have seen while having an incredible adventure. It just also happens to be one of the Seven Summits too!
Come join our world-class guide team on one of the world’s most sought-after peaks. You will not be disappointed by the experience. Because of the remoteness and logistical challenges involved with this climb we only offer one departure per year so spaces are limited and they tend to go quickly.
We have chosen to fly both in and out of the mountain for many reason, the main one being safety. We feel that the risks associated with trekking into base camp are too great and out of our comfort zone given that it is impossible for us to mitigate them. Once you experience the helicopter service and the amenities that we provide on our Carstensz climb, you will be pleased you decided to climb Carstensz the right way — focusing on climbing rather than jungle mud-slogging!
We have been fine-tuning our Carstensz logistics for many years, and I literally wrote the book on the Seven Summits. We employ a slow acclimatization schedule to make sure that you are properly adjusted to the rarefied air and have the best chance of success. Come join us for this amazing, life changing experience- one that you will one-day tell your grandkids about.
We look forward to helping you achieve success on Carstensz Pyramid. Please don’t hesitate to contact me directly regarding the expedition if you have any further questions.
Best regards,
Mike Hamill

- Best expedition at a great value: CTSS believes in providing our clients with the highest quality service in the industry at a great value. Climbing and trekking are our passion, and our goal is to share these unique places and experiences with you. We want you to feel good about your experience because we believe word-of-mouth is the best advertising, and that begins with satisfied customers. There is a difference between our expeditions and those of our competitors, especially local cut-rate options. In choosing us, you are hiring the finest guides and logistical support in the industry. Benefiting from well over 100 high-altitude expeditions and drawing on decades of first-hand guiding experience, we have worked hard to refine our logistics in order to offer you the highest chance of success at an exceptional value.
- We are a modestly sized guide service with highly personalized service: We maintain a moderate size so that we can tailor our Carstensz Pyramid experience to you. Not all climbers are the same, which is why Mike Hamill will work with you directly to make sure you choose only the programs that are right for you.
- The best route: CTSS climbs Carstensz by the beautiful normal route. By using this route, we provide you with the highest chance of success and give you the best climbing experience available on the mountain. We also provide you with more than ample time to acclimatize to the altitude so you feel good on summit day. Many climbing companies, especially local ones, race you up and down the mountain not allowing time to get used to the rarefied air. This is not only not advantageous to you but it is dangerous. We also fly you both in and out of the mountain in a helicopter. It is dangerous and incredibly time-consuming to take the trekking approach, and it takes the focus off the climbing route and summit. Using the helicopter is a huge advantage that improves safety and success, and these are our three main objectives. You will see when you’re on the mountain that there’s no better way to climb the peak than the way we have organized it.
- Leadership: As the expedition organizer, Mike’s almost unparalleled experience based on high altitude can make the difference between success and failure. From start to finish, he will work with you to make sure you’re as prepared as possible to reach your goal of standing on top of Oceania. Often, being able to troubleshoot problems before they occur can make all the difference, and this is where Mike’s vast experience becomes crucial. Please visit our Success Rates page for more information.
- The Seven Summits specialist! Climbing the Seven Summits is THE Seven Summits specialist. We focus primarily on the mountains of the Seven Summits, and Carstensz is one of our signature climbs. With hundreds of high-altitude expeditions under our belts, we are well-prepared to create the perfect climbing experience for you. We love the diversity of the “Seven Summits” and the challenge of climbing them all, which is why we focus on these climbs in particular.
- Best guides: The quality of an expedition is, in large part, dictated by the individual guide(s) leading the trip. CTSS hires only the finest guides operating at the highest standards for client care who are highly trained, well respected in the industry, and close friends that we trust. They have excellent personalities and are some of the most experienced professionals in the world. Mike and the rest of our guides are strong leaders who maintain high standards. Our guides make our company what it is and have extensive resumes of personal climbs, high altitude guiding, and certifications. All our lead guides maintain at least a Wilderness First Responder medical standard or equivalent. Our local guides around the world are the best in the industry and do an amazing job helping you attain your goals and navigating local obstacles.
- Safety: Our primary goal at CTSS is safety. We have an unparalleled safety record, and our clientele’s well-being factors into every decision we make while on expeditions. Although we like to stand on the top of mountains more than anyone, we believe that climbing is a round-trip endeavor, and getting you back to your loved ones safely is paramount. We take many safety precautions, including bringing multiple communication devices, high-altitude safety equipment, medical kits, and the highest-quality gear to ensure a safe environment in which to climb.
- Success: Success rates on expeditions under Mike’s leadership are among the best in the business. This is a testament to our quality of service and attention to detail. Mike and our team of guides are incredibly proud of their summit success and work hard to get their clients to the top. As Mike says, “You can’t buy a summit, but you can buy better odds.” With our expertise, experience, and infrastructure, you can stack those odds in your favor. We offer a longer acclimatization progression for proper acclimatization to mitigate the risks of altitude sickness. Many guide services race their clients up the mountain, especially local companies, to cut corners on costs. We are highly invested in our reputation for safety and success and are always striving to improve our programs to maintain our hard-earned status. Decision-making in the mountains is supremely important, and our guides are the best in the business, have a hunger to summit whenever it’s safe to do so, and have a proven track record. All of our programs acclimatize conservatively to mitigate the risk of having altitude issues and to give them the highest chance of success.
- You!: Why choose us? Because of you! We consistently attract the best clients and believe this is because we offer the highest quality expedition at a great value. Our clientele takes the time to educate themselves about their options and choose us because of this. We feel that surrounding yourself with the right people will make you successful, and that goes for guide service owners, guides, and even those with whom you climb. Having a team with the right attitude and camaraderie is a key factor in making you successful.
- Logistics: We have led countless high-altitude expeditions and have perfected the logistics, allowing you to focus on climbing, safety, and success. We eat well and live well on expedition. We want you to feel as comfortable as possible while on your climb or safari to not be distracted from the task at hand. We feel that these creature comforts go a long way to making your time in the backcountry enjoyable. We strive to work with the best local outfitters and provide the best local logistics, hands down.
- Updates: In today’s connected world, people want to know how things are going on the expedition. CTSS maintains regular updates on our blog to keep friends and families informed. This can relieve a lot of the stress loved ones have when you’re away climbing. We want to make the climb stress-free for both the climber and the folks back home.
- Professional Business Practices: Running a professional guide service that you feel comfortable putting your trust in is important to us. We comply with all local, state, federal, and international laws. We hope that this makes you feel more confident about choosing us and our programs.
- Enjoyment: This is your vacation, and you’re here to have a good time. Our goal is to give you the experience of a lifetime, inspire you in the mountains, and have a great time doing it. This, again, comes back to our guides; they all have great personalities, and their love for the mountain is contagious.
- Low client-to-guide ratio: We operate all of our trips at a low client-to-guide ratio, which offers you a better, safer, and more personalized experience.
“Great leaders like Mike inspire and lead people to take on challenges and achieve great things.” – Tim Igo
- Carstensz Pyramid sits in Irian Jaya, which is part of Indonesia
- Carstensz Pyramid entails the most consistently steep and technical climbing of all the Seven Summits
- Some native tribes in Papua still practice cannibalism
- Patrick Morrow was the first person to finish the Seven Summits with the Carstensz variation
- Dutch explorer Jan Carstensz was the first European to sight the peak in 1623
The climbing on Carstensz consists mainly of steep rock climbing. From base camp the route winds its way up a series of gulleys following fixed lines to the top of a ridge. The climbing is fun and positive with great friction even when it’s raining, albeit somewhat steep and exposed in sections. The steepest steps consist of moderate 5th class climbing on fixed lines. Leather gloves are highly recommended due to the extremely rough texture of the rock.
Once on the ridge the route traverses the ridge and undulates up and down following the path of least resistance. After crossing the famous cable bridge it’s a short scramble to the summit. The descent consists mainly of rappelling on steep fixed lines reversing course from the ascent.
Climbing Carstensz requires serious fitness, an ability to perform well at altitude, the mindset to be away from home for several weeks, and a desire for rugged adventure travel. The Sudirman Range is still a very remote and rugged place with few of the amenities we have come to expect. We try to give our climbers all of the creature comforts that we can but at the end of the day this is true adventure travel!
Climbers need to have experience rock climbing and using fixedlines and ascenders. Also, cramponing skill, knowledge of self-arrest technique and ice axe use are valuable but not a pre-requisite. If you want to join this expedition but don’t have these skills we can work with you to get you up to speed prior to the climb. Please let us know how we can help!
Day 1: Meet in Timika, Indonesia: Our team will meet you at the airport and transfer you to our hotel. This is a pure arrival day. You may arrive at any time and shake off the jetlag.
Day 2: Gear checks and team meeting: We will meet at breakfast and set a plan for the day. We will organize a team meeting that will get everyone up to speed on the details of the trip before diving into gear checks. Once gear checks are complete we will check in with the immigration office in Timika and pick up any last-minute supplies. We will have a team dinner before heading to bed early.
Day 3: We rise early and have a 5am breakfast before transferring to the airport and checking in with the local helicopter service. We will then take our morning flight (approx 40mins) to Yellow Valley Basecamp (4,250m) At Base Camp we will acclimatize. Sleep, read, relax, take a light walk around Base Camp. Whatever you do – stay hydrated!
Day 4: Acclimatization day: We spend today getting used to the altitude and continuing our acclimatization. Today we will do some rope training ahead of a summit plan briefing and an early dinner.
Day 5: Summit Days. We wake up at 1am and prepare for our summit. We will have a very light meal and a hot drink to kick start our bodies before we start trekking at 2am. Our route follows the ridge crest with grand exposure along the way. We pass four small notches as we rappel and use ascenders to negotiate trickier rock climbing sections. Our descent entails multiple rappels and scrambles. The rock is clean and provides excellent friction even when wet. You can expect a summit day of 10-12 hours round trip.
Day 6: We rise early to pack our equipment. Our helicopters could arrive as early as 6Am. We are picked up from Yellow Valley Basecamp and returned to Timika where we are met at the airport and transferred to our hotel.
Day 7: Fly Home. Check out of our hotel and transfer back to the hotel for our onward flights, either to Bali or Jakarta.
Day 8– 14: Contingency days: Since the weather is such a huge factor in most Carstensz climbs. We advise booking your flexible return airfare a week beyond your expected departure day and moving it forward if your expedition goes to schedule.
Note: Weather is a huge factor in this expedition! Teams have waited for weeks to get in and out of base camp and some teams haven’t even made it in. This is a real possibility. EXPECT weather delays. This is true adventure travel so you need to relax, roll with the punches, bring a good book and music, and book flexible return airfares.
This detailed gear list is provided for your reference. Please follow these guidelines carefully because if you arrive in Indonesia missing gear you will be required to track them down prior to the climb at your own expense which can be difficult (if not impossible) and costly. Please make sure you are fully prepared so that your trip and that of your teammates goes smoothly. If you have any questions about the gear, please give us a call, and we can discuss: we’re here to help! Note: There are strict weight limitations for the helicopter flight so bring only what you need and not more. That being said, if you are unsure about items you can bring them to Timika for the gear check and make the final decision there. You can leave some stuff in a duffel at the hotel in Timika.

Each expedition is led by Mike Hamill.
Mike Hamill, lead guide and owner of CTSS, is universally regarded as one of the most experienced and respected high altitude mountaineers and expedition leaders in the world.
He has personally guided thousands of climbers on the Seven Summits and well over 150 climbers have stood atop 8000m peaks, including Everest with him. A guide for over 20 years, he boasts a 91% expedition success rate and an 83% climber summit success rate for all of his expeditions worldwide.
He has stood on top of Everest 6x and currently holds the record for most non-Sherpa summits of Cho Oyu. He’s also the author of the guidebook “Climbing the Seven Summits,”
To complement his leadership, Mike has hand-picked a selection of the finest mountaineering professionals from around the world to make up the international CTSS guiding team.
Our team are highly qualified and some of the most highly experienced climbers in the world. Chosen for their attention to detail, safety records along with their fun, genuine and caring personalities, we have no hesitation in saying they are the best. Mike holds the CTSS staff to the same high standards as he holds himself.
Who you choose for expedition organization and leadership is a big deal – it can be the difference between a great expedition and a miserable, potentially dangerous one and you only want the best in your corner. The fact that Mike and his guides have an unprecedented safety record should be a paramount consideration in who you choose to climb with.
Mike and the CTSS team’s love for the mountains and adventure continues in our corporate social responsibility policy. A portion of profits and fundraising climbs are organized every year in support of the “Tiger of the Snows Fund” a not-for-profit that provides grants to further education of mountain tourism workers and their families.

Everest Base Camp is perhaps the most iconic trek in the world and for good reason. This stunningly scenic pilgrimage into the high Himalayas is not only a grand adventure that will take you to the foot of the highest mountain on earth but it is also a deep personal challenge that should be on everyone’s bucket list.
Winding your way up through the Khumbu Valley, you can expect to pass through enchanted rhododendron forests, stay in quaint villages, camp on a living, breathing glacier that forms on Mt. Everest and be enveloped by views of our planet’s most breathtaking mountains. Not for the faint-hearted, it’s physical for sure but nevertheless achievable for anyone willing to put in a little training.
What makes the beauty and excitement of trekking in this majestic landscape even better is the hospitable Sherpa culture. Sherpa are renown the world over for their graciousness and generosity and the moment you step foot on the trail you too, will know why.
- Cross one of the world’s greatest treks off your bucket list
- Be a team member and be part of an Everest climbing expedition
- Stay at Everest Base Camp proper where the summiteers reside
- Experience and appreciate Sherpa culture, food, and hospitality
- Climb the famous Kala Pathar for spectacular views of Everest in her entirety
- See Everest and the Himalayas from the air while flying to and from Lukla

How Our Everest Base Camp Trek is Unique
We encourage you to research your many options when it comes to picking a guide service for your dream Everest Base Camp trek. As a popular trek, we know that there is a huge variety of operators to chose from who offer different trek styles and therefore prices. A few ways in which we differ and add value to our trips are:
- You will spend 2x nights in our luxury camp on the Khumbu glacier inside Base Camp Proper rather than down valley in a teahouse far away from the action. (Most trekking companies that aren't affiliated with an actual Everest climbing team are not allowed to stay in camp and simply tag 'trekkers rock' which is located on the outskirts of camp before returning down valley. Very few even enter base camp itself which is a shame as you miss out on the scene and community of Everest expedition life.
- You have the opportunity to take part in a 'Climbing Clinic' and learn ice-climbing and rapelling in the safe base of Khumbu icefall where we will help you take some great hero photos to remember your experience (Technically you'll be able to say you've climbed on Everest!)
- Trek alongside real Everest Guides and aspiring summit climbers, be part of a summit expedition as a front row witness to all the action and understand what really goes into an Everest Expedition!
This is perhaps the best and most iconic trek in the world! Hiking to Everest base camp should be on everyone’s bucket list. What makes the beauty and excitement of trekking in this majestic land even better is being part of the lovely and hospitable Sherpa culture. Sherpa are known the world over for their graciousness and generosity.
Enjoy spending time visiting famous cultural and religious sights on our way through this scenic valley in the shadow of the world’s highest mountains. Our slow acclimatization schedule means there is plenty of time to explore landmarks like the famous Tengboche Monastery where you can stop by to visit a High Lama and receive a blessing, take time to explore the famous Namche Bazaar – the Sherpa capital or have a beer in the world’s highest pub. Passing by countless Tibetan Buddhist stupas and chortens, you will feel the rich culture of Tibetan Buddhism come alive.
We choose to implement a slow acclimatization schedule, not just so you can take in the sights and sounds of the valley but to ensure you enjoy your trek and feel great. Altitude isn’t something to be feared, it’s achievable for most people but it isn’t a process that can be rushed. Treks that move too quickly often have disgruntled, unwell people because their bodies are struggling to adjust.
Yes, trekking to Mt. Everest base camp requires good fitness but it is an achievable goal. You need have the mindset to be away from home for several weeks, along with the desire for adventure travel. The Khumbu is still a remote place with few of the creature comforts we have come to expect at home so it’s best to suspend your expectations of 5 star luxury, super smooth trails and blazing fast internet. In fact, when you embrace it, you’ll enjoy the slower pace of life and being a little disconnected from the rush of the Western world. That said we do our best and select teahouses that are clean, have great food and offer hot showers and 3rd party wifi internet for purchase.
The CTSS Mt. Everest base camp trek begins in Kathmandu where we obtain our permits and encourage you to enjoy a day checking out the city before beginning the trek in to base camp via the Khumbu Valley by flying in to Lukla to begin your expedition which will see you trek to over 17,600ft/5,400m!
Throughout time the human desire to explore new places has been part of our DNA and the world’s highest mountain, Everest, is an incredible draw. Trekking to its base camp is one of the world’s most sought after adventures and for good reason. Not only is it spectacularly beautiful, it is a challenging adventure that anyone should be proud of.
Trekking within a CTSS Everest expedition is an opportunity to experience what a real Mt. Everest climbing team experiences, from the thoughts and feelings of the team on the approach to what life is like at base camp. It’s a rare chance that few people have to gain a true insight into what it is to climb the world’s grandest peak. Most Base Camp treks aren’t affiliated with Everest expeditions and therefore aren’t able to stay at Base Camp proper. They simply reach the outskirts of the camp, tag ‘Trekker’s Rock’ and turn around. They rarely get to spend time or speak to the mountaineering community at all.
If you’re interested in mountaineering or what goes into an Everest expedition then this is a great trek.
As the premier high altitude guide service, CTSS is committed to your safety and success. We are not a huge “trekking factory” but a modestly sized, nimble guide service that prides itself in customizing our program to your individual needs.
In choosing us you are hiring the finest guides and logistical support in the industry. Benefiting from countless Himalayan expeditions and treks and drawing on decades of first hand guiding experience, we have worked hard to refine our logistics in order to offer you the highest chance of success at an exceptional value. In fact, I personally lead our Everest base camp.
Further, we invite our Everest climbers to ask their friends and family to join them on this exotic journey by jumping on our Everest base camp Trek, Lobuche climb, or Everest C2 and C3 programs. You will be able to share many of the cultural experiences together and they will even be able to spend some time with you at base camp and possibly above. This time together often makes these long expeditions more “do-able” from a time away perspective.
We look forward to sharing a great experience with you on the Mt. Everest base camp trek.
Best regards,
Mike Hamill
Owner and Director, Climbing the Seven Summits
- Trek with a real Everest/Lhotse climbing team: This is your opportunity to peer into what an actual Everest/Lhotse climbing team goes through on the approach to base camp. You will get to know the personalities and Sherpa that will attempt to stand on the top of the world. This adds a very unique aspect to the world’s most breath-taking trek.
- Stay at Everest Base Camp: Because you are associated with an actual climbing team you are allowed to stay at Everest base camp. This option is not open to other trekkers but is one of the best parts of an Everest base camp trek and to miss it would be a huge loss. Most trekking groups reach the beginning of camp and turn around to rush back to their teahouse for the night. You will spend the night at base camp with the climbers and have time to walk around and experience the community. What’s more, you can even walk a short way into the first, safe part of the Khumbu icefall to see what it’s like.
- Best Value: We have worked hard to create the best trek at the best price. We implore you to do your homework and look closely at what others offer in terms of leadership, ability to stay at Everest base camp and camp accommodations, quality of food, guide experience, logistics, hotels, acclimatization schedule, Sherpa expertise, personal service and professionalism. We firmly believe that comfortable, well-nourished, healthy trekkers are strong and successful trekkers. An Everest base camp trek is too important to not look closely at the details and we are here to answer your questions. We want you feel 100% confident in joining our team. We have spared no expense and yet still offer you the best rates in the industry.
- The best teahouses: CTSS always stays at some of the finest teahouses in the valley. We choose our teahouses based upon quality of accommodations, hygiene and cleanliness, food and hospitality. Everest base camp trek teahouses are rustic to be sure, and this is adventure travel. Even so, you will be in relative luxury.
- The best guides: This is hugely important- please research the quality and experience of your guides thoroughly. All of our guides have extensive knowledge of the region and have proven themselves at altitude time and again. Many of them have dozens of trips to Nepal and have stood on top of Mt. Everest so can talk to what it’s like to climb the mountain.
- Highest paid Sherpa: We purposely pay our Sherpa more than anyone so that they are happy and take care of our clients. Year in, year out we can attract the best talent. Our world-class team of Sherpa are hand-picked by Sirdar Tendi Sherpa and CTSS owner Mike Hamill to ensure we have the cream of the crop. They are all close friends who we have complete confidence in. Because they are paid well they go the extra mile to make sure base camp is exceptional and that our clients are extremely well taken care of. Once they’ve been selected for the team, they go through intensive training and a 5-day review process which includes mountain medicine, client care, technical rescue, and guiding principles before being ok’ed to work. We believe in our Sherpa and know that they will do a great job for you and become friends for life.
At CTSS we offer the widest variety of trek options as well as a Lobuche climb so that you can customize your Mt. Everest base camp trek experience to your trekking style, ability, interests and budget. A Mt. Everest base camp trek should not be “one size fits all.”
Mt. Everest Base Camp Trek – $5,495 USD
Annually:
- April 3rd – April 22nd – SOLD OUT! Join our waitlist.
- April 12th – May 1st
- October 15th – November 2nd (Please note in offseason; Everest Base Camp is not set up so itinerary varies – contact office for details)
The Everest base camp trek is widely heralded as the best trek in the world, and for good reason.
This trek takes you from Kathmandu by plane to Lukla at the head of the Khumbu valley. From there you trek roughly 40 miles/70 km through the lush green pastures, blossoming Rhododendron forests, up into the most precipitous mountain terrain one can imagine. En route to Everest base camp you get to experience the famous Sherpa culture and hospitality while taking in the views of literally the tallest mountains on earth.
At Everest Base Camp Proper you will spend 2x nights in our Expedition Camp, with the opportunity to do a beginner friendly ice climbing/mountaineering skills clinic in the lower part of the Khumbu Glacier, time to hang out in the famed ‘Big House’ Dome complete with unlimited cappuccinos from the world’s highest cafe, play a game of the world’s highest ping pong table! and relax taking in vistas over the icefall.
After your unique stay at Base Camp, you will retrace your steps back down valley, before flying back to Kathmandu, and onward home.

The terminus of your trek is Everest base camp at 17,600ft/ 5,500m where, since you are affiliated with an Everest climbing expedition, you are allowed to spend a night at base camp. This allows you to get a sense of the Everest base camp scene and community while other trekking groups don’t get this luxury. You even have the option to scale Kala Pathar the morning you leave base camp for stunning views of the Everest Massif, Lhotse and Nuptse.
This trek is ideal for anyone who wants to challenge themselves and is a great option for families and friends of CTSS climbers. They can join the trek in, stay at base camp proper (which is not open to everyday trekkers) & get a first-hand experience of being part of a Mt. Everest and Lhotse expedition.
For tentative itinerary, please see schedule tabs below
*We highly recommend adding further contingency days on the end of your trip and booking a flexible fare for the return flight home. Flights can sometimes be delayed out of the Khumbu due to mountain weather. Please note CTSS covers one night in Kathmandu at the end of your trip.
Lobuche East Climb
April 1 – April 22*: $6,995 USD
Lobuche Peak is a jewel of the Himalaya and offers perhaps the best summit view in the world! Lobuche is surrounded by the tallest peaks on earth and the view from the summit peers out on the Everest/Lhotse/Nuptse massif, Makalu, Pumori, Ama Dablam, Cho Oyu, Thamserku, and many others. This is a great first Himalayan climb and a great training peak for taller mountains such as Aconcagua, Ama Dablam, and Cho Oyu. To consider an ascent of Lobuche East peak participants must be familiar with crampon and ice axe technique and have used a harness before. We will run a training refresher at Lobuche base camp before the ascent so if you are a little rusty, don’t worry, we will get you up to speed. If you’re not sure if you have the experience for this climb, please ask us. If not, we can recommend other training to get prepared for a Lobuche ascent.
If you’re a climber your friends and family can join you on your acclimatization climb of Lobuche en route to Everest and challenge themselves on steep fixed-line climbing up rock, snow, and ice.
For tentative itinerary, please see schedule tabs below
*We highly recommend adding further contingency days on the end of your trip and booking a flexible fare for the return flight home. Flights can sometimes be delayed out of the Khumbu due to mountain weather. Please note CTSS covers one night in Kathmandu at the end of your trip.

Looking to climb Mt. Everest in the future and interested in getting real training on her slopes under your belt? Looking to climb Cho Oyu or another first 8000m peak?

CTSS Custom and Private Climbs: (contact us for customization and current pricing)
We pride ourselves on our ability to customize your trek to suit your needs. As a smaller team, we can fully customize your trek to you, and in fact we encourage this customization. A Mt Everest base camp trek should not be one size fits all. We offer the most options (see expedition options) because we believe every trekker has individual needs. Our personalization and client care are second to none. DON’T get lost in the numbers and join a large team where quality and personal attention suffer.
Allowing you to customize your expedition to suit your needs and budget is a huge priority for us. As mountaineers ourselves, we understand that it’s the little things that can make the difference and not everyone is the same when it comes to their approach. Therefore we encourage you to tailor your expedition and talk to us about any other options you may wish for.
Single rooming option: $1250 USD
We are happy to organize single rooming accommodations and a tea house upgrade for you throughout the expedition. If you snore or are easily awakened by others that do snore, this might be a great option. We stay at some of the nicest teahouses in the Khumbu valley throughout our trek to keep you healthy and to provide you with comfort. Many teahouses offer room upgrades which may include an en suite bathroom with hot shower and more space, whereas our normal rooms generally have a shared bathroom and shower for an added fee.
Shared Helicopter to Lukla at the end of the climb: $3,495 USD
Many trekkers are anxious to get home to family and friends as quickly as possible after two months in the mountains. Because of this, we offer to arrange a private helicopter for you from Everest base camp to Lukla to avoid the three day, 40 mile walk back down the valley. It’s also a once in a lifetime experience in it’s own right and an incredible way to see what you have trekked from the air and take a scenic flight amongst the Himalaya. From Lukla you will either catch a flight that day or spend the night before catching your regularly scheduled flight back to Kathmandu. Taking a helicopter to Lukla and a fixed wing plane back to Kathmandu, rather than a helicopter the entire way saves many thousands of dollars.
Shared Helicopter to Kathmandu at the end of the climb: $5,995 USD
For those that aren’t as price sensitive and who want to get back to Kathmandu and homeward bound as quickly as possible at the end of the trek, we can arrange a private helicopter for you directly from Everest base camp to Kathmandu. This avoids the three day, 40 mile walk back down the valley and waiting for a night in Lula for a flight back to Kathmandu. It’s also a once in a lifetime experience in it’s own right and an incredible way to see what you have trekked from the air and take a scenic flight amongst the Himalaya.
Kathmandu Cultural City Tour – $250 per person
Kathmandu is one of the most exciting, culturally rich cities in the world. Unique, and overflowing with sights, smells, sounds and tastes, it’s both chaotic and charming. A city of true contrast it needs to be experienced to be understood. During our Kathmandu Cultural Tour an English speaking guide will show you the best history and UNESCO sites the city has to offer.
Additional Nights at Everest Base Camp: $350 USD per night
If trekkers want to stay at base camp longer than the itinerary we can add additional nights for $250/each. If you would like to stay longer than a week you will need a Nuptse climbing permit which allows you to stay at base camp throughout the entire Everest expedition season. Please contact us directly to arrange this.
Gokyo Return Extension – $1,495 USD per person
Once you’ve achieved your goal of Everest Base Camp, why not make your return a little different and rather than retracing your footprints back down the Khumbu valley, instead spend a few days seeking some new scenery by visiting the Gokyo region. Gokyo itself is a small hamlet of stone houses and one of the highest settlements in the world, surrounded by truly breathtaking vistas, mountains and glaciers.
You’ll see and experience more of these amazing mighty Himalayan mountains, climb the famous Cho La Pass (5,420m) escape the madding crowds and view the stunning Gokyo Lakes before rejoining the main trail at Namche Bazaar for the final day’s trek back to Lukla.
This extension is best suited to experienced and fit trekkers who are keen to get off the beaten path and further challenge themselves.
Dietary restrictions accommodation: (please let us know, no charge)
We can accommodate just about any dietary restriction if you let us know far enough in advance. Please make us aware of any restrictions you may have and we will do our best to create healthy and satisfying options.

Our Mt. Everest base camp trek meets in Kathmandu where we obtain our permits, run through gear checks and have a team meeting. Following our time in Kathmandu we fly to Lukla to start the trek. We land at the Hillary runway at roughly 9,000ft/3,000m. From the moment you land in Lukla you will be at altitude. It’s important to take it easy and let your body adjust to the altitude naturally. From here we make our way up the Khumbu valley staying at some of the best teahouses in the region in order to mitigate the stress so you can focus on the climb.
Hygiene is incredibly important to us and we take many precautions to make sure our team avoids getting sick. Despite this, illness can be a fact of life in Nepal so chances are people will at least experience a stomach rumbling at some point during the trek.
Once en route we use a slow, methodical acclimatization strategy to position ourselves for the summit bid. Most treks rush this process and suffer the consequences of altitude illness because of it.
Our base camp is the finest on the mountain. We spare little expense making you feel as comfortable as possible. Our top-notch cooks make you the healthiest food possible with strong hygiene standards.
Gear List: This gear list has been carefully compiled over years of treks and expeditions. Please take it seriously. All of the items on the list are mandatory. If you don’t have all the items on the list you will be required to purchase them in Kathmandu. Please contact us for specific items or more details on items. Specific items change too fast for us to recommend a certain model so it’s best to email us for real-time product info. Please support our partners: We work closely with Mountain Gear out of Washington State in the USA. If you purchase through the link at the bottom of our home page they will give you a discount and they are also available to help you select the right gear if you let them know you are with Climbing the Seven Summits.

Everest Base Camp FAQ
Absolutely, you are a valued team member and meeting your needs are just as important to us. Many trekkers worry that they aren’t “fit” enough to be joining a summit climbing team and that they might not be able to keep up or that their concerns will fall to the bottom of the priority list. Rest assured, that is not the case.
All our team/s move at a very manageable pace, slow acclimatization is important for everyone regardless of how much training or experience you have. Our schedule is achievable for everyone and we take plenty of breaks and rest days.
We also staff our treks well to ensure that everyone can keep their own pace and go as fast or as slowly as they chose and still have guidance. Sometimes climbers like to stretch their legs a bit but there is no need to feel rushed or that you must keep up or be together at all times. Everyone’s bodies respond differently and we understand that.
enough staff that everyone can keep their own pace, fast or as slow as you like
Altitude sickness or AMS is a common concern, but you don’t need to worry, or have any prior experience at altitude to be successful. We purposely keep a very slow acclimatization schedule to allow you plenty of time to acclimatize naturally. Slow and steady wins the race as such. We still encourage you to speak to your doctor about your options as there are medications like diamox that help with acclimatization with few side effects that many people find helpful but this is a personal choice.
All of our staff are trained to look for and spot signs of altitude sickness and will manage them immediately.
A few things to look out for are headaches, lack of appetite and shortness of breath. Remember when you are on the trek, there’s no need to push stoically through in silence, tough it out, or worry about holding others back. Please speak up about how you are feeling so we can adjust your pace, schedule etc to ensure your success. There is plenty of room in the itinerary to do that. Afterall, some of the best climbers/trekkers in the world acclimatize slowly, so don’t feel ashamed if you need to take your time.
On the trek to BC we will be eating meals prepared for us by the teahouse staff. We stay at some of the finest teahouses so the food is the best available in the Khumbu. We can cater for dietary requirements but we do need prior notice.
At base camp, our food is the finest on Mt. Everest. Our head chef Kumar has been cooking for Everest expeditions for more than a decade and trains at 5 star hotels in the off-season.
You are welcome and encouraged to bring some of your favorite snacks, although we provide plenty of food and there is opportunity to purchase snacks along the trail, some people find it comforting to have their favorite, familiar treats from home
Yes, if you have not selected the Single Room Upgrade. the majority of the teahouse accommodations along the trek are twin share.
We stay at a five-star hotel in Kathmandu and in the finest teahouses while trekking to base camp. While at Everest Base Camp, you will be sharing a tent. If you are climbing above base camp, or staying for a prolonged period with our expedition, you will have your own tent at Base Camp (above Base Camp you will share a tent with another climber to reduce the number of dangerous loads the Sherpa need to carry through the treacherous Khumbu Ice fall and for warmth)
In general, trekking packs are relatively light. You will likely be carrying 5lbs – 10lbs (2kg – 5kg) most of the time on the trek into base camp.
If you are climbing you should be prepared to carry your gear for the day and some of your personal gear for the mountain. Sherpa will carry all of the group gear and help with personal gear.
Yes. Trip delay and cancellation, rescue, repatriation, medical insurance is mandatory for this program for your own benefit. We have seen too many times people need to cancel their trip either before or during the trek for reasons such as injury, health, family and business matters. With such a long trip and so much at stake climbers need to be prepared for contingencies.
“Mike, there’s an aura about you that when you’re around everything will be ok. You chose the right profession, and I’m a better person because of it!! Cheers!!” -Bart W
“And I will never forget that you believed in me when I didn’t believe in myself. For that I will always be grateful to you.” Jason V
“It’s not often that you get to have the privilege of climbing with a world class climber, such as yourself. Wow. And here’s an added bonus… you’re a really nice guy, too… down to earth and not an ounce of pretension. Seriously, we couldn’t have enjoyed our time with you more. You illustrated the utmost level of caution and consideration for the team and not only that, you were a blast to hang out with. Thank you for your patience with me, for pushing me beyond my comfort level, and for your wisdom and care to make it to the top. You taught me a lot about climbing and about myself. I appreciate you tremendously and know that without you, I wouldn’t have made it. This was one hell of a trip and we will always think of you fondly… and hope to climb with you again. Thank you, Mike and enjoy your next adventure.” Angela H
“Mike, we knew by reputation, but I did not expect such a down-to-earth, humble, approachable person. Mike welcomed us and made us feel like we all belonged. He taught us about climbing every day. He encouraged us when we did well and he pointed out our mistakes in a positive way. He made an effort to get to know each of us individually- we were all different people to him, not just a bunch of clients. And on summit morning his leadership and decision making were incredible. Every one of us has incredible respect for Mike. I cannot imagine ever doing something like this again without him.” Doug B
“I had the time of my life on the EBC trek and am so grateful for the opportunity! I truly had lots of fun every day meeting and getting to know people from all over the world, learning about the Nepal culture, eating their food, listening to everyone’s stories (so inspirational), and I felt connected to so many people. The Sherpa, all guides, cooks, staff, and porters were simply the best! No doubt, CTSS employs quality, compassionate, funny, knowledgeable, and inspiring team members to ensure our safety, well-being, and happiness along the journey! Very pleased with the entire CTSS logistics and total operations. Again, thanks to CTSS, I had the joy and best experience of a lifetime! I look forward to returning to Nepal in the near future and continuing my journeys through more treks and mountain climbs around the globe with none other than CTSS!” – Julie M. EBC Trek 2024
Denali
Denali Expedition
Difficulty Level: Intermediate - Advanced
Lying in the heart of the 600 mile long (960 km long) Alaska Range, Denali is the largest mountain in North America, rising 20,320 feet (6194 m) above sea level. Denali towers almost 18,000 feet (5500m) above the surrounding tundra, giving it more vertical rise than Mount Everest.
In the native Athabaskan, Denali means “The Great One” and indeed, that it is!
- Walk in the footsteps of Bradford and Barbara Washburn, the West Buttress first-ascenionists, while climbing the same route
- Boldly tick 'Wild Alaska' off of your bucket list
- Land on a glacier in a ski plane in the remote mountains
- Climb on a mountain where the sun never really sets
- Celebrate your success listening to live music in the Fairview Pub with a host of other climbers from around the world
***On Denali, CTSS works exclusively with Mountain Trip, an authorized concessionaire of Denali National Park. Owner Mike Hamill has been leading expeditions on Denali for nearly two decades and handpicks our Denali partner to ensure CTSS’ logistics, professional support, and local knowledge.
Climbing the Seven Summits is committed to providing the highest quality Denali expedition with our partners Mountain Trip. You can be assured that it will be both challenging and fun, a true once in a lifetime.
Denali is truly rugged and known to have some of the worst weather in the world, at a latitude of 63 degrees North, Denali is just 200miles South of the Arctic Circle. Every year it attracts climbers from all over the world including the world’s best alpinists to test themselves on the peak that many consider to be the most challenging of the Seven Summits. Not only for the extreme conditions but also the workload required. Climbers need to be able to carry all their own gear, make their own camps and prepare their own food as a team, unlike other mountains where high altitude porters help with the work.
As such an expedition on Denali requires lots of planning and preparation, perhaps more than any of the other Seven Summits. It is a serious, gear intensive climb that requires plenty of advanced planning to ensure success. We utilise our breadth of experience, detailed logistics and our partnership with Mountain Trip to take much of this planning headache away from our climbers, but we still require them to be focused and committed to the climb ahead.
Most climbers fly into Anchorage before transporting themselves to Talkeetna, which is where our expedition begins. Here we will conduct gear checks, pack and have a number of briefings. When the weather permits we approach the mountain on a glacier ski plane, enjoying a forty minute flight that boasts incredible views of Denali and the surrounding peaks. We land on the ice at the South East fork of the Kahiltna Glacier and unload at Base Camp and begin our climb.
We use the normal route being ‘The West Buttress Route’ which this offers the most direct route up and interesting climbing. Climbing via this route usually takes two to three weeks but we allow a month, door to door, to allow for bad weather days and a safe, conservative climbing schedule.
From Base Camp, the route ascends the main branch of the Kahiltna Glacier up moderate terrain surrounded by the largest and most forbidding mountains in North America. It is mainly lower-angle glacier travel heading North until Camp 3 where the pitch steepens as it gains the upper reaches of the mountain, climbing exposed ridges, snow slopes and smaller glaciers heading North and East. The West Buttress Route climbs nearly 13,000 vertical feet in 18miles making it one of the biggest climbs of the Seven Summits circuit.
From Base Camp and across the lower glacier, a night schedule is established to climb during the the coldest hours on the lower glacier when the crevasse bridges are the safest. The intense heat of the direct sun during the day makes it unsafe and uncomfortable and during the Alaskan summer the night is sunlit so there is no need for a head lamp.
Across the climb we employ ‘a climb high, sleep low, double carry’ strategy to systematically move up the mountain and cache gear, whilst acclimitizing. There are 4 camps that we use before the summit. Summit day is a long, serious day in a hostile environment with most climbers averaging eight to ten hours to the summit and another three to four to descend back to High Camp.
Denali National Park and Preserve keep a staff of highly trained climbing rangers on the mountain during climbing season. Their job is to facilitate the climb, keep the mountain clean, relay weather information and provide rescue service and helicopter should climbers need it. While reassuring, it is important to be self sufficient and judicious while on the mountain so the rangers don’t have to put themselves at risk unnecessarily. Denali is a potentially dangerous mountain and climbing at nearly 6,000 meters is very serious.
This expedition will be organized and led by Mike Hamill, Owner of Climbing the Seven Summits alongside our field partners Mountain Trip. Mike has personally guided nearly 20 Denali expeditions and is committed to helping the CTSS climbers navigate and succeed through all of the exciting challenges of Denali whilst remaining safe.
Welcome to “Climbing the Seven Summits” Denali Expedition
Denali is one of the most imposing mountains on earth and is considered one of the hardest climbs because of it’s extreme weather and serious terrain. I joke that I return to guide Denali each year to prove to myself I’m still a hardcore mountaineer. It is consistently the hardest and most arduous work of of any of the Seven Summits and a real climbers mountain.
As such, it is one of the most sought after of the famed “Seven Summits” and shouldn’t be underestimated. Climbers need to be able to carry very heavy loads as there is no support from porters or pack animals available, meaning the achievement of the summit is that much sweeter, but the responsibility of the workload falls entirely onto the climbers’ shoulders. Summiting is no easy feat but I am committed to helping you achieve it and with the right preparation and expedition set up, I have no doubt you will.
Benefiting from nearly 20 Denali expeditions and drawing on decades of first hand guiding experience I am committed to sharing my knowledge with you and providing you with all the resources you need for a successful climb. I’m proud to have led well over 100 people to the summit, and excited to continue to share that memorable moment with more mountaineers in the future.
We look forward to sharing a great experience with you on Denali. Please contact me directly regarding the expedition should you have any questions.
Best regards,
Mike Hamill

Difficulty: Intermediate to Advanced
Climbing Denali requires serious fitness and an ability to perform well at altitude. Climbers need solid cramponing, general knowledge or glacier travel and crevasse rescue as well as knowledge of fixed line climbing, rope work, knots, and hitches. Experience climbing at altitude is a plus. If you don’t have these skills we can work with you to get you up to speed prior to the climbs. Please let us know how we can help! Our mountaineering seminars teach skills specific for climbing Denali and other Himalayan peaks. This isn’t the place to start your Seven Summits bid: instead climb smaller, less serious peaks first to work your way up to Denali.
The following is a sample itinerary for a Denali expedition. Keep in mind that weather on Denali can be difficult, flights in and out of the range can be delayed, and conditions can dictate movement on the mountain so the actual schedule is rarely the one described here.

This detailed gear list is provided for your reference. Each item has been selected over many Denali expeditions. Please follow these guidelines carefully.

If you have any questions about the gear, please give us a call and we can discuss it: we’re here to help!

We feel that choosing the right guide service for a high altitude climb such as Denali is one of the most important decisions you will make. Expedition leadership is of paramount importance when it comes to safety, success, and the overall enjoyment on an expedition. We strongly believe our organization is the best in the business; better than our competitors both domestic and international. Some of the reasons we believe we can offer you the best experience at an exceptional value are as follows. We are here to help you make an informed decision so please feel free to contact us directly.
- Best expedition at a great value: CTSS believes in providing our clients with the highest quality service in the industry at a great value. Climbing and trekking is our passion and our goal is to share these unique places and experiences with you. We want you to feel good about your experience because we believe word-of-mouth is the best advertising, and that begins with satisfied customers. There is a difference between our expeditions and those of our competitors, especially local cut-rate options. In choosing us you are hiring the finest guides and logistical support in the industry. Benefiting from nearly 20 Denali expeditions, well over 100 high altitude expeditions, and drawing on decades of first-hand guiding experience, we have worked hard to refine our logistics in order to offer you the highest chance of success at an exceptional value.
- We are a modestly sized guide service with highly personalized service: We maintain a moderate size so that we can tailor our Denali experience to you. Not all climbers are the same, and this is why Mike Hamill will work with you directly to make sure you choose only the programs that are right for you. Don’t get lost in the numbers with one of the larger “climbing factories”. They can’t give you the attention to detail you need for climbing a peak as important as Denali.
- The best route: CTSS climbs Denali by the beautiful West Buttress route. By using this route ,we provide you with the highest chance of success and give you the best climbing experience available on the mountain. This is due to the more relaxed terrain and greater amount of time for acclimatization en route to the summit. You will see when you’re on the mountain that there’s no better way to climb the peak than via the West Buttress route.
- The Seven Summits specialist! Climbing the Seven Summits is THE Seven Summits specialist. We focus primarily on the mountains of the Seven Summits, and Denali is one of our favorite mountains. We have been perfecting our logistics on Denali for decades to create the perfect climbing experience for you. We love the diversity of the “Seven Summits” and the challenge of climbing them all, and that is why we focus on these climbs in particular.
- Best guides: The quality of an expedition is, in large part, dictated by the individual guide(s) leading the trip. CTSS hires only the finest guides operating at the highest standards for client care who are highly trained, well respected in the industry, and close friends that we trust. They have excellent personalities and are some of the most experienced professionals in the world. Mike and the rest of our guides are strong leaders who hold the high standards you’d expect from the premier expedition company. Our guides make our company what it is and have extensive resumes of personal climbs, high-altitude guided climbs, and certifications. All our lead guides maintain at least a Wilderness First Responder medical standard. Our Sherpa and local guides around the world are the best in the industry and do an amazing job helping you attain your goals and navigating local obstacles.
- Safety: Our primary goal at CTSS is safety. We have an unparalleled safety record, and our clientele’s well-being factors into every decision we make while on expeditions. Although we like to stand on the top of mountains more than anyone, we believe that climbing is a round-trip endeavor, and getting you back to your loved ones safely is paramount. We take many safety precautions, including bringing multiple communication devices, high-altitude safety equipment, medical kits, and the highest-quality gear to ensure a safe environment in which to climb.
- Success: Success rates on expeditions under Mike’s leadership are among the best in the business. (please refer to the summit statistics chart for more details). Mike has maintained an excellent success rate for expeditions under his direct guidance on Denali. This is a testament to our small, personalized service and attention to detail. Mike and our team of guides are incredibly proud of their summit success and work hard to get their clients to the top. As Mike says, “You can’t buy a summit, but you can buy better odds.” With our expertise, experience, and infrastructure, you can stack those odds in your favor. We offer a longer acclimatization progression for proper acclimatization to mitigate the risks of altitude sickness. Many guide services race their clients up the mountain, especially local companies, to cut corners on costs. We are highly invested in our reputation for safety and success and are always striving to improve our programs to maintain our hard-earned status. Decision-making in the mountains is supremely important, and our guides are the best in the business, have a hunger to summit on any trip, it’s safe to do so, and have a proven track record. All of our programs acclimatize conservatively to mitigate the risk of having altitude issues and to give them the highest chance of success.
- You!: Why choose us? Because of you! We consistently attract the best clients and believe this is because we offer the highest quality expedition at a great value. Our clientele takes the time to educate themselves about their options and choose us because of this. We feel that surrounding yourself with the right people will make you successful, and that goes for guide service owners, guides, and even those you climb with. Having a team with the right attitude and camaraderie is a key factor in making you successful.
- Logistics: Our partnership with our concessionaire partner, Mountain Trip, provides you with the finest logistics on offer. Mountain Trip has been outfitting Denali expeditions for decades and is simply the best in the business. Our logistics, flight service, food, etc, are the best available. This means eating well and living well. We feel that these creature comforts go a long way to making the time in the backcountry enjoyable. We work with the best local outfitters and provide the best local logistics, hands down.
- Professional Business Practices: Running a professional guide service that you feel comfortable putting your trust in is important to us. Because of this, we comply with all local, state, federal, and international laws. We hope that this makes you feel more confident about choosing us and our programs.
- Enjoyment: This is your vacation, and you’re here to have a good time. Our goal is to give you the experience of a lifetime, inspire you in the mountains, and have a great time doing it. This, again, comes back to our guides; they all have great personalities, and their love for the mountain is contagious.
- Because you care about giving back and local communities, a portion of the profit from each program goes to the “Tiger of the Snows Fund.” CTSS Owner Mike Hamill began TOTs in 2014 to provide educational opportunities for workers involved in outdoor tourism and their families globally. Visit the website at www.tigerofthesnows.com. By climbing or trekking with CTSS, you are making a conscious decision to be a global citizen and support education and local communities. In supporting “The Tiger of the Snows Foundation,” CTSS is creating stronger communities and giving back to the people who give us so much on our expeditions in the best way we know how: education.
- Low client-to-guide ratio: We operate all of our trips at a low client-to-guide ratio, which offers you a better, safer, and more personalized experience.

Denali FAQ
Yes, the mountain tents will be shared accommodations due to limited tent space and the weight of carrying extra tents.
In general, climbing packs on Denali are about as heavy as you will see anywhere. You will be climbing everything you need for 3 weeks in a cold and extreme environment on your back and in a sled. You will leave base camp with over 100lbs of gear which you will split up to double carry to camps up the mountain. You will then need to cary all of your equipment down and off the mountain in one go.
Yes. Trip delay and cancellation, rescue, repatriation, medical insurance is mandatory for this program for your own benefit. We have seen too many times people need to cancel their trip either before or during the expedition for reasons such as injury, health, family and business matters. With such a long trip and so much at stake, climbers need to be prepared for contingencies.
In general our food on and off the mountain is excellent. There are several good restaurants in town, and the food on the mountain is first rate. Our partners at Mountain Trip make every effort to make sure you have the best, healthiest, lightest, and heartiest food of any company on Denali.

Don't take our word for it... Hear it directly from the climber's mouth
"I climbed Mount Vinson in Antarctica with CTSS. Their leadership was outstanding. Not only did they help me in any possible way during my months of preparation with tips and all necessary paperwork, they continued showing and executing their professionalism on the mountain as well. The food was excellent and added to the mood of the team. They really made the effort, over and over again, to include the team in decision making and made sure everyone got the attention they needed during a big climb like this. Absolutely fabulous. I highly recommend CTSS.”
- Arnaud, Netherlands

"I am transformed forever! If you want a life-changing, positive experience with guides who have heart and tons of experience for your personalized journey to the summit, CTSS and its local guides are the Mount Kilimanjaro choice. Ethical business practices that build up guide/porter team families and the local economy, made me feel happy to be their clients in even more ways. Do it now!"

"I had the time of my life on the EBC trek and am so grateful for the opportunity! I truly had lots of fun every day meeting and getting to know people from all over the world, learning about the Nepal culture, eating their food, listening to everyone's stories (so inspirational), and I felt connected to so many people. The Sherpa, all guides, cooks, staff, and porters were simply the best! No doubt, CTSS employs quality, compassionate, funny, knowledgeable, and inspiring team members to ensure our safety, well-being, and happiness along the journey! Very pleased with the entire CTSS logistics and total operations. Again, thanks to CTSS, I had the joy and best experience of a lifetime! I look forward to returning to Nepal in the near future and continuing my journeys through more treks and mountain climbs around the globe with none other than CTSS!"
— Julie M, United States

An incredible experience from start to finish. I can’t say enough what a difference it makes to have a great guide who cares so much about the whole experience and a great time to make the journey so special. I hope this is the first of many climbs with CTSS for me.Kevin A, USA
I cannot even put into words how incredible that trip was for me – you truly run everything top notch and it shows in every single part of the trip. Your patience in teaching/coaching in a way that I didn’t feel intimidated by was amazing and so so appreciated. I am in awe of this whole experienceJulie M, USA
As expected you run a first class show from start to finish… I look forward to the next adventure.Len F, USA
“Tendi Sherpa – a truly amazing person and an inspirational leader… It is plain to see that the leaders of the other guiding companies hold him in the highest regard. As a client that gives you great confidence in your leader’s decision making. It was that decision making that made it such a successful trip. Thank you Tendi.”Richard W
“Tendi is a true superstar of the Himalayas. Under his ever watchful eye, he allowed me to build confidence, learn new skills and gain faith in myself. Seemingly everywhere at once, Tendi was always there ready and willing to assist me on how to climb smarter and safer. Kind, inspiring, courteous, strong and always smiling. There are truly no words I can write that do him justice. I look forward to more climbs with Tendi in the future” Peter W
“I had the pleasure of being guided by Tendi Sherpa, the most humble and respected individual on Mt. Everest. Tendi is famous in Nepal and widely regarded as one of the top three Sherpa. I have never met a more positive individual in my life, his laugh and smile are a permanent smile from Kathmandu airport to the roof of the world and back. During the 6 weeks we spent climbing together, he never once overlooked a clip, anchor or footstep. I can confidently say there is no safer way of climbing the tallest mountain in the world than by having Tendi by your side. With twelve Everest summits and perfect English, Tendi is like a Western guide on steroids. My favorite analogy was when I was told ‘Tendi could climb faster without oxygen and with me on his back, than I could running 6 liters per minute of oxygen” And it’s true! If you are going to take the time to climb Everest there’s no better way to stack the odds in your favor than climbing with Tendi Sherpa as your guide.”(Mat Wood – Dual Everest and Lhotse summiteer in under 24 hours)

CTSS is a class act! The team and facilities are world class. Every detail of the expedition was perfect. Mike’s decision making, Tendi’s guidance, the strength of our Sherpa team and the food Kumar was producing were second to none. You only had to see the look on the faces of team members from other operators…to know we had something special. I can’t wait to climb with CTSS again.Peter W
After doing research on the various Everest mountaineering guide companies, I could find no reason to use anyone other than Climbing The Seven Summits. Now that I’ve returned from a successful summit of Mt. Everest with CTSS, I would highly recommend them to any climber, for any summit in the world. CTSS provides an unparalleled level of guide expertise, and very experienced Sherpa support staff, as well as exceptional accommodations and sustenance. All of this, at very competitive pricing, with different levels of service available, depending on the climber’s experience. Mike Hamill has the highest level of integrity and mountaineering expertise, constantly adapting to the needs of the team members, as well as the changes on the mountain. CTSS has significantly raised the bar in the mountaineering world – and all the other companies know it.William B, (USA)
Having climbed and summited a few mountains with Mike, including Everest, Cho Oyu and Denali, I signed up with CTSS for Lhotse. From the beginning everything just worked. Paperwork was quick and efficient. Superb Base Camp set-up: tent, food, water, hygiene. Great team dynamics with the Everest climbers on the CTSS team. The Sherpa Mike gave me was compatible with me and I with him. The logistical planning Mike did for my climb was of a high quality, including daily weather reports and interpretation thereof, choosing dates for my rotations, and most importantly, planning my summit rotation in the smallest possible detail with contingencies built in for unplanned events. I called Mike from the summit of Lhotse at 6:30am on 19 May 2018. This Lhotse expedition ranks right up there as one of my best ever mountain experiences - could not have been better. 10/10. Thanks, Mike.Louis Carstens - 4x8,000m Seven Summits
"The word trust comes to mind when I think about CTSS and why I will continue to engage them in future. When undertaking activities as serious as mountain climbing you need people you can trust, not to just make the good times happen but who have your back if things go bad.”
- Scott Gorman

Thank you again for the trip of a lifetime.Rick B.
Mike, The trip was terrific. I was extremely impressed with your leadership qualities.Pete
Thanks you for showing me the great World of high altitude climbing on Aconcagua. It had a lasting impact on me personally and my climbing, and it was due to you!Ann S.
(Thanks) for all your help and guidance on the recent trip to Aconcagua. Your knowledge and experience are invaluable. I hope I get a chance to climb with you again soon.Mark G.
Again, thanks for an awesome adventure. It’s the people, the friendship and the camaraderie that make up for more than half of the experience. Thanks for being so great!! and getting me up and down that hill safely. I look forward to climbing with you again in the future.Jason V.
Thank you for a fantastic trip!Jordan W.
I wanted to thank you for the great experience of climbing and summiting Aconcagua. Your leadership of our group was great and I really enjoyed climbing and conversing with you. You have the right blend of experience, expertise, personality and leadership skills to manage such trips/climbs really well. I am looking forward to the prospect of climbing again with you in the coming months/years. Maybe Cho Oyu over the next few years.Bavesh P.
Thanks for a great trip! Can’t wait for the next adventure with you!Masha G.
Thanks Mike for an amazing expedition! These days will always remain on my mind.Vicky J.
I had the time of my life on Aconcagua. The trip was absolutely incredible, two weeks that I will treasure for the rest of my life. I have to say that Mike made the trip. He just inspires confidence and security. I knew that no matter what happened up there he could fix it for us. I would climb anything with him.Nicky M.
You’re one of the superhumans (by that I mean observant, thoughtful, authentic — as well as superman on a mountain) so I hope to know you for years to come!Jo M.
Mike Hamill — Seasoned pro, classic lead guide, everything you want in a team leader and I consider myself lucky/privileged to get to climb with him. I’m sort of thinking Superman but with the ego of Clark Kent… Everything that Mike could do to make better, he did make better and his judgement was excellent. The call he made to go for the summit was amazing.Ken S.
Thanks for an awesome trip on Aconcagua! You guys were excellent!Mike M.
Mike, there’s an aura about you that when you’re around everything will be ok. You chose the right profession, and I’m a better person because of it!! Cheers!!Bart W.
You are the very best — I’m glad we know you!Julie S.
“You guys are doing a fantastic job and although I’m just a client, I felt proud to be wearing a CTSS cap and it probably sounds silly but I felt honoured to hold the CTSS flag on the summit because of the way you conduct yourselves as a company. The way the expedition was put together was professional yet relaxed and I enjoyed every bit of it, seriously, the best experience of my life.”
- Tom D, Australia

"I recently had the privilege of embarking on a climbing expedition and summit attempt to Aconcagua, and I cannot express enough how exceptional the entire experience was. Opting for CTSS's custom private climb marked my second journey with CTSS and guide Nanika ‘Nani’. The custom private climb allows for greater flexibility in the schedule and additional time for acclimatization to the higher altitude. From start to finish, every aspect of the trip was meticulously organized, showcasing a level of professionalism and guide competency that truly set this adventure apart."
Organization: The organization of the Aconcagua expedition was impeccable. Right from the initial planning stages to the moment we descended from the summit, every detail was thoughtfully considered. Pre-trip communication was clear and thorough, ensuring that I was well-prepared for the challenges that lay ahead. Logistics, including transportation, accommodation, and meal arrangements, ran seamlessly, allowing me to focus on the climb itself. The attention to detail was evident, creating a sense of confidence and ease throughout the entire journey.
Guide: The expertise and professionalism of Nani were truly commendable. Nani's knowledge of Aconcagua and mountaineering in general instilled a sense of trust and security. Nani demonstrated exceptional patience while providing insightful guidance on technique and safety measures. His commitment to ensuring my well-being was unwavering, and his passion for the mountain and its history enriched the entire experience. His professionalism and dedication went above and beyond, making the ascent not only safe but also incredibly rewarding."
Overall: The overall experience of climbing Aconcagua with CTSS’s private custom program surpassed all of my expectations. The supporting staff and facilities on the mountain were top-notch, creating a supportive environment. The logistics implemented for safety were outstanding, providing an additional layer of reassurance. The breathtaking landscapes and challenging ascents made this expedition an unforgettable journey. I wholeheartedly recommend CTSS’s Aconcagua expedition. The meticulous organization, guide competency, and overall experience created a once-in-a-lifetime adventure that will be etched in my memory forever. If you are seeking a challenging yet rewarding mountaineering experience, look no further - this expedition is the epitome of excellence.

A heartfelt thank you for another great adventure. I appreciate so much your patience and support. I’m looking forward to the next one — the challenge of training and preparing for it as well as the experience of living it… Great job!Jean D.
Thanks you for an amazing trip and climb of Denali! Memory of a lifetime!Warren W.
Mike, Thank you for helping me realize my dream of climbing the Seven Summits. I am glad our paths crossed in 2009 on Elbrus and we have had the opportunity to climb together. Your coaching, leadership, and mentoring have been instrumental in my growth as a mountaineer and a person. If it was not for your positive encouragement in 2010 after climbing Aconcagua I don’t know that I would’ve seized the opportunity to go climb Everest. It has been an amazing journey with a lot of great accomplishment and memories along the path to success. I am grateful that I have shared those experiences with you. Thank you again for all you have done to support me in my pursuit of the dream to climb the Seven Summits.Tim I.
It was a true honor to have been part of your team. I feel blessed to have spent time with one of the greatest modern mountain guides.Mark K.
Again, thank you for leading my best climb ever!Turner B.
I have to start with Mike here. I was a fan of his from Cho Oyu last year, and he didn’t let me down this year. Mike is a fantastic leader in all respects. His judgement is sound, he’s not afraid to make tough calls, he’s diplomatic, he takes charge and leads by example, he ensures good team morale, he’s technically brilliant, and he takes appropriate risks to ensure success. He was constantly examining the terrain for safety at all times in the lead and really had to make some tough calls about when to go up. He’s also a great conversationalist.Vanessa O.
We really enjoyed being with you for our 6th of the 7 summits! Thank you for all of your help, advice and wisdom to get all of us up and down Vinson safely.Kriss B.
Great climb! I really enjoyed your leadership. You made the right call all the time and I never worried about safety. And you handled difficult situation with professionalism. Terrific job! Thanks!Jim W.
It seems most guides can get clients up a mountain when all conditions are perfect, but the real pros shine when chaos strikes. I talked to several clients from other teams, and they were in disarray the morning of the storm. People straggling down on their own. Scary stuff. You handled our team with precision. Great communication with the members with briefings and what you expected for the next day. It was a honor to meet and climb with you.Mark K. (former NFL Player)
Mike, Thanks you for all your efforts in making this a successful expedition and introduction to Russia. It was a revelation to watch you work to help each team member have the best chance for summiting, but still look out for the welfare of the entire team.Scot B.
Mike, Thanks to you an ordinary Joe (me) got a chance to do something special. I will never forget everything you did for me and for our team. I wish you all the best.Doug B.
The word trust comes to mind when I think about CTSS and why I will continue to engage them in future. When crossing timezones, exploring foreign countries and undertaking activities as serious as mountain climbing you need people who you can trust, not to just make the good times happen but who will have your back if things go bad. CTSS demonstrated a high level of trust to me in three ways on this expedition: Firstly, CTSS has the capability to get things organised, delivered and done in a country far away from home. Everything ran smoothly, and we were provided with lots of information. Secondly, CTSS worked with a high standard of supporting guides. Each guide was hand picked by Mike and could demonstrate a track record beyond what was required for Aconcagua. I also found each guide to be personable, unique and lots of fun to work with. A special shout out to Luis who led us from camp each morning playing the flute! Also to Sasha who is an inspiring guide from Russia who would always lead the way with her big smile and warm heart. Finally, the team culture. Mike sets the tone for how he wants the team to behave ahead of time and leads by example. What this resulted in was a group of people who arrived as mountaineers, formed into a strong team and left as life long friends in just three weeks. It’s true that climbing the seven summits is a tough adventure and maybe not for those who only seek the peaceful sunrays of a tropical beach. However, for those with the capability and determination to embark on this journey of a lifetime, I hope the above gives you the confidence to put your trust in CTSSScott G (Australia)
After doing research on the various Everest mountaineering guide companies, I could find no reason to use anyone other than Climbing The Seven Summits. Now that I’ve returned from a successful summit of Mt. Everest with CTSS, I would highly recommend them to any climber, for any summit in the world. CTSS provides an unparalleled level of guide expertise, and very experienced Sherpa support staff, as well as exceptional accommodations and sustenance. All of this is provided at very competitive pricing, with different levels of service available, depending on the climber’s experience. Mike Hamill has the highest level of integrity and mountaineering expertise, constantly adapting to the needs of the team members, as well as the changes in the mountain. CTSS has significantly raised the bar in the mountaineering world – and all the other companies know it.William B, USA (Everest Summiteer 2019)
