White Water Rafting

Why Nepal's rivers are good

Water falling from 8,000 m to 100 m in under 200 km makes for steep, continuous, high-volume rivers. Nepal has a genuine claim to some of the best commercially run whitewater anywhere, and the Sun Koshi is regularly listed among the world's great river journeys.

Choosing a river

Trishuli — Grade 3, half to two days. On the Kathmandu–Pokhara road, so it slots into any itinerary with no detour. Warm, forgiving, busy. The right first river and fine for families.

Seti — Grade 2–3, two days. Warmer and gentler than the Trishuli with good beach camping. The best choice with children or for anyone nervous about the whole idea.

Bhote Koshi — Grade 4–5, one day. Steep, continuous and technical, three hours from Kathmandu. One of the steepest rivers run commercially anywhere. Genuinely demanding; not a first trip.

Kali Gandaki — Grade 4, three days. Remote gorge, no road alongside, temples and villages on the banks. The best three-day trip in Nepal, and the one we recommend most often to people who want more than a taster.

Sun Koshi — Grade 4–5, eight to nine days. 270 km through eastern Nepal, self-supported, camping on beaches. A serious expedition and, for those who have done it, usually the highlight of the country.

Season matters more than on land

River grades in Nepal are not fixed — they change with flow.

September to early December. Post-monsoon, high water, biggest rapids. October is peak. A Grade 4 river in October is meaningfully harder than the same river in March.

March to early June. Lower, warmer water, more technical reading of lines, less raw power. Good for learning.

Monsoon (mid-June to August). Most commercial rafting stops. Flows are dangerous and debris is real.

What a day on the water is like

You are briefed on the bank — paddle commands, what to do if you swim, how to get back in the boat — then you are on the water for four to six hours with a beach lunch in the middle. Six to eight people per raft, one guide steering from the back, everyone paddling.

On overnight trips you camp on sand beaches the road cannot reach, which is much of the appeal. Bring quick-dry clothes, sandals that fasten, sunscreen and a dry bag for anything you cannot replace. Leave cotton, phones and anything with a battery in the vehicle.

Safety questions worth asking

Rafting in Nepal is lightly regulated, and standards vary more than in almost any other activity here. Before booking with anyone, ask: is there a safety kayaker on the water; are the guides currently certified in swiftwater rescue; how old are the rafts and PFDs; and what is the guest-to-guide ratio.

We carry a safety kayaker on every Grade 4 and above trip. If an operator quotes noticeably less than others, that is usually the line item missing.
