The Bhote Kosi is known as the River from Tibet and you can start a trip after a peak over the border into Tibet. The Kathmandu / Lhasa Highway (AKA Friendship Highway, Arniko Highway) runs along beside the river. You can run a day trip or do a two-day expedition and run parts of the river twice. It’s a great beginner river for rafters and fun for kayakers at all levels.
Bhote Koshi River Rafting is the beautiful for adventure trip with very steep and basically non-stop mountain river only 3 hours drives from Kathmandu offering two days of intense and challenging river activity.
