Best Time to Trek in Nepal

The short answer: autumn (late September to November) and spring (March to May) are the best times to trek in Nepal, offering the clearest skies and most stable trail conditions across almost every region.

Autumn follows the summer monsoon, so trails are washed clean, visibility is at its best, and daytime temperatures are comfortable even at altitude. It is the busiest season on routes like Everest Base Camp and Annapurna Circuit, so book accommodation and permits with more lead time.

Spring brings warmer temperatures and blooming rhododendron forests, particularly striking on routes like Ghorepani Poon Hill. Afternoon cloud build-up is more common than in autumn, but mornings are typically clear.

Winter (December to February) can still work for lower-altitude routes such as Ghorepani Poon Hill or Langtang's lower stages, but high passes like Thorong La or Larke La become significantly harder and sometimes close.

Monsoon (June to August) is generally avoided for the classic routes due to rain, leeches and poor visibility — with one notable exception: Upper Mustang sits in a rain shadow and remains trekkable through the summer.
