How altitude affects your body, how we pace our treks, and the simple habits that keep you feeling strong.

Altitude sickness doesn't care how fit you are. What matters is giving your body time to adapt — and that's built into every itinerary we run.

Climb high, sleep low

Above 3,000 m we aim to raise our sleeping altitude by no more than 300–500 m per day, with rest days every few days.

Habits that help

  • Drink three to four litres of water a day
  • Walk slowly — you should be able to talk
  • Eat well, even when appetite drops
  • Tell your guide about headaches early
The best acclimatisation tool is patience. The mountains will still be there tomorrow.
