Trekking season is possible at any time of the year depending on where you are going for trek. The most popular seasons are spring (March-April - May) and autumn (September-October - November). Winter is very cold above 4,000 meter and high mountain passes may be snowbound, but it is good for trekking at lower altitude in Nepal. During the monsoon season (June-July -August), you can do trek in the rain-shadow areas north of the Himalayan like upper Mustang, upper Dolpo and Tibet. These places are out of reach of the rain clouds because of the high mountains and are unaffected by the monsoon.
