May to October, the best months to trek in Dolpo
With less than 50 mm annual rainfall, Dolpo is Nepal’s only trekking destination, which can be trekked from May to the end of October. Unlike Trekking Regions of Nepal, which are not recommended to trek from May to October, Dolpo has this advantage.
Treks in Dolpo are closed from November to January because of the heavy snowfall in the region. The snowfall could happen until April and hence treks in Dolpo are recommended during this time of the year as well.
