May: Late spring, before the monsoon. Conditions in the Himalaya change from valley to valley and year to year, so treat this page as a planning guide, not a forecast. Check current conditions with your operator or the local forest or tourism office before you commit.
Weather and temperature
Warm days at lower altitudes and cold nights higher up. The Sikkim rhododendron bloom is described as thinner than in April.
Snow conditions
Sikkim upper trails can still hold snow. Kashmir trails remain snow-covered before the summer window opens. Ladakh is in spring, with melting snow at altitude.
Road access and transport disruptions
Roads are generally open in much of the region. High passes may still be opening.
Daylight
Long, bright days.
Crowds
May is a popular school-holiday month for many trekkers. We have not verified crowd numbers.
Difficulty considerations
Heat in the foothills and lingering snow high up both add effort. Start early.
Beginner suitability
Many moderate routes are a good fit, if your fitness is up to the altitude.
Treks that work in May
Also possible, but not the best window
