Trishuli River is the most famous destination for river rafting in Kathmandu. Originating in the Himalayas, Trishuli River provides the ideal rapids for those trying white water rafting for the first time. January to May are the best time to try this adventure as the waters are calmer at that time. Trisuli rafting begins at Chaurandi and ends at Gaighat. White water rafting in Trishula River is also the best way to travel for those heading from Kathmandu to Pokhran instead of taking a flight or the road.
