Sun Koshi/Tamur

This classic river trip is famous for being one of the top ten river journeys in the world. The ever changing scenery helps to ensure that every day on the river is exciting and different. The beginning of the trip sees high mountains, open valley, forests and small remote villages. The final days bring you to open plains and the thriving village of Chatara.

The rapids encountered at the beginning of Sun koshi trip are fairly relaxed class 3, giving an excellent opportunity for great teamwork to really develop. As the river winds its way across the country the size of the rapids increase and it is not unknown for villagers watching from the riverbank to lose sight of the raft in the huge waters!
The unique Sun Kosi trip above ending with a short drive and camping on the adjoining Tamur River.The next morning, we will raft the Tamur, which is a very powerful and exciting river with over 30 Class 4+ rapids in rapid succession. After rejoining the Sun Koshi, we camp at the confluence, and then the next morning we raft to Chatara and return to Kathmandu. This extra day trip to Tamur is the best way to end the Sun Koshi experience.
This is an ideal trip for those wanting to combine peaceful stretches of stunning scenery, some challenging rapids and the experience of a lengthy trip where lifelong friendships can often begin.
