Trekking in Nepal can be undertaken throughout the year. There are four seasons in Nepal. Each season has its distinct attractions to offer. The seasons are classified as follows
Spring (Mar. – May)
Different varieties of wild flowers, most notably the rhododendrons, make the hillside above 5000 meters a haunting paradise during this season. It is mildly warm at lower elevations, and at higher elevations over 4000 meters, the mountain views are excellent and temperature is quite moderate.
Summer (June – Aug.)
Summer starts from June and continues up to mid-September and constitutes the monsoon season. During this season, trekking is wet and warm. Also, this time is good for the keen botanist as the higher valleys and meadows blossom with flowers and lush vegetation. It is not recommend to trek during summer months.
Autumn(Sept. – Nov.)
This season offers excellent weather and tantalizing mountain views.
Winter (Dec – Feb)
This season is noted for occasional snowfall only at higher elevations. Hence it is ideal for trekking at lower elevation, generally below 3000 meters.
