Season notes from our guide
The best months are October and November, with clear skies and stable weather, and March to May, when the rhododendrons flower but clouds build in the afternoon. These are also the busiest months, when Bamboo, Deurali, MBC and ABC fill up. December to February is clear but cold, with snow above Deurali and a real avalanche risk. June to September is the monsoon: daily rain, leeches, landslides on the lower trail and roads, and few views. Check the weather and the trail before you go in any season.
