Altitude Sickness: The Symptoms Guides Actually Watch For

Headache is the obvious one. Appetite, balance and how you sleep tell a guide more, and they tell it earlier.

Our guides write these notes between seasons, while the details are still fresh. They cover what changed on the ground: a rebuilt bridge, a lodge that closed, a section of trail rerouted after monsoon.

Where a post gives numbers — altitudes, walking hours, permit costs — those come from the most recent departure we ran on that route, not from a brochure. If something has changed since you read it, tell us and we will update the page.

Questions about how this applies to your own trip are best answered directly. Our specialists reply to route questions the same day, whether or not you have booked anything.
