Which route you chose is important. Both sides of the mountain have pros and cons. CTSS favours the South Side of Everest (from Nepal) for these reasons:

• The South Side has better opportunity for infrastructure which means better facilities, more assurances and rescue capability including helicopter access
• The HRA (Himalayan Rescue Association) at base camp is a medical clinic manned with speciality trained doctors 24/7
• In the event of a rescue; we can get helicopter access up to Camp 2, meaning definitive care is within a few hours vs days on the North Side
• The South Side has a steeper approach which allows you to drop back to lower altitudes more quickly and efficiently, meaning a better quality of rest and recuperation between rotations
• The South Side is a milder environment vs the drier, dustier, windier North Side
• The border to Tibet has been closed to climbers multiple times, on very short notice over the last 10 years, and as such we have greater confidence in reliably accessing the mountain from the South Side.
