Typical seasonal exposure along the route, merged from the stops that have a place page. Seasonal patterns only, never conditions today.
Altitudehigh in a typical yearAll year
At roughly 3,361 m, thin air affects most people. General information, not medical advice: gain height slowly, build in acclimatisation days, learn the symptoms of altitude sickness (headache, nausea, breathlessness, broken sleep) and go down if they get worse. See a doctor before travelling and carry insurance that covers helicopter evacuation.

Landslideshigh in a typical yearJun-Sep
The approach up the Budhi Gandaki and the forested lower Tsum trail are landslide-prone in the June to September monsoon; the upper valley is drier but the way in is the problem.
