When is the best season to trek in Nepal?

There are four main seasons in Nepal. The best seasons to visit in Nepal are spring & autumn. Trekkers can start from “Mid-February to Early June” & “Mid-September to late November”. The rainy or summer seasons are not suitable for trekking because of the rain. However, Mustang & Dolpo region towards north-west of Dhaulagiri doesn’t receive rain as the cloud flowing from the south is blocked by the range. So, trekking can be organized in these areas even in “summer”.
