ALTITUDE SICKNESS

Plan the ascent, not just the destination.

Use these destination guides to understand whether altitude is a meaningful part of your trip, what to watch for, and how to plan a slower arrival when the route goes high.

The practical rule

Risk is driven more by elevation and ascent profile than by fitness. If symptoms appear after ascent, do not keep climbing just to stay on schedule.

Not every mountain destination has the same altitude risk. Choose the actual place below rather than treating every elevated city or mountain range as equivalent.

Destination altitude guides

Choose by risk profile first. A city stay, a high mountain climb and a route-dependent trek do not need the same altitude plan.

Higher-risk destinations

Trips where sleeping elevation or rapid ascent makes acclimatization a real part of planning.

3 guides

Route-dependent destinations

Risk changes with the route, sleeping elevation and how high your itinerary actually goes.

8 guides

City elevation questions

Elevated cities where visitors may notice the height, but classic acute mountain sickness is generally not expected.

2 guides

Lower to moderate risk destinations

Places where classic altitude illness is less likely for typical visitors, though elevation and exertion still matter.
