Prepare to Trek: Training, Altitude & Permits

Written by Kei ·Updated 30 Jul 2026

Trek preparation that isn’t tied to one route — the training, altitude know-how and permits you need for any Himalayan trek. Every claim here is measured, sourced and dated, or clearly flagged as educational rather than medical advice.

Frequently asked

How do I train for a high-altitude trek?
Train the descent as hard as the climb, walk with a loaded pack (8–11 kg), and build cold tolerance gradually. Cardio for the altitude is only half the job — see the training guides below.
How do I avoid altitude sickness?
Ascend slowly, sleep low relative to your day's high point, hydrate, and know the warning signs. The one rule that overrides the rest: if symptoms worsen, descend. See the altitude guide.
What permits do I need for the Annapurna region?
The ACAP permit for the conservation area, plus a contested guide requirement. Full detail, cost and current status in the permits guide below.

Keep planning

  • Cold-weather training — What actually builds cold tolerance for a trek - and what's hype (and dangerous).
  • Trek preparation — Altitude is the genuine danger up high. The golden rules, the warning signs, and the one rule that saves lives — descend.
  • Annapurna Circuit — The ACAP cost, the TIMS confusion, and the contested guide rule — official line vs on-the-ground reality, sourced and dated.
  • Annapurna Base Camp — A short, steep climb into the glacial sanctuary ringed by Annapurna's peaks.
  • Everest Base Camp — Ten days up the Khumbu valley to the foot of Everest — high, cold and remote.
