One of the finest big volume rafting and kayaking trips in Nepal and definitely the best combination trip, trekking, white water rafting and wilderness.

The Karnali is Nepal's longest and largest river and with its tributaries, it drains most of the Far West of Nepal. The rapids are also pretty wild, with the river building to its climax in these lower canyons. In terms of volume, the river is comparable to the Sun Kosi, but the Karnali is more constrained by its canyon walls, giving bigger, mote continuous and serious rapids. This constrained nature of the river means that any increase in volume has more pronounced effect on the difficulty of the rapids and this makes it a river that is best run at low flows. Highest extreme instantaneous discharge measured at Chisapani was an incredible 21,700 cumecs.

The trek to start of the river trip is pleasant and highly scenic. It climbs through mixed forest and then traverses two ridge tops with excellent panoramic views of the Bheri forests.
