Season Calendar: Annapurna Base Camp

The Annapurna Base Camp Year

October to November and March to April are the two windows worth planning around. There is no flight to gamble on, which makes the quiet months kinder here than in the Khumbu, but the avalanche corridor above Deurali is what decides winter.
