Trekking in the Himalayas
Trekking is possible at anytime of the year depending on where you
are going. The most popular seasons are spring (February-May) and autumn
(September-December). Winter is very cold above 4000m and high mountain
passes may be snowbound, but it is good for trekking at lower
altitudes. During the monsoon season (June-August), you can trek in the
rain-shadow areas north of the Himalayan like Mustang, upper Manang and
Dolpo.
Monsoon
Monsoon season (June – August) is considered to be the most
unattractive time for tourist activities due to the heavy rains. Many
people decide not to visit Nepal during this period of time, especially
after reading some disappointing information regarding the monsoon
definition. Even though the amounts of rains are considerably higher
compared to the peak season, there are still plenty of activities and
opportunities for adventure. Many first time trekkers who trek during
the monsoon are still very satisfied with their first experience. Also
what makes the trek more unique and personal is the extremely small
amount of tourist on the trek compared to peak season. You can avoid
monsoon by trekking in the rain-shadow areas north of the Himalayas
(Mustang, Upper Manang and Dolpo). Rain clouds simply reach these areas
because of the high mountains, therefore they are unaffected by the
monsoon.
