Best time to travel in Nepal

sherpasanam:
There are four seasons in Nepal - Autumn, Winter, Spring & Summer.

1. For Trekking, Expedition,Rafting & Mountain flight = Autumn (Sep, Octo & Nove)
and Spring (March,April & May)

= October and April are the peak season, very crowded in the hiking area.
So its better to visit either Sept/Nov or March/May.

2. For sight seeing, jungle safari, Paragliding ect. = Autumn (Sep, Octo & Nove)
Spring (March,April & May) and Winter ( Dece, Janu,& Feb )
