Bhote Koshi Rafting
Short, steep and continuous, the Bhote Koshi packs some of Nepal's most intense Grade IV-V rapids into a single thrilling day near the Tibet border.
The Bhote Koshi is Nepal's adrenaline day-trip. Dropping steeply from the Tibet border, it crams continuous Grade IV–V rapids into a short distance, giving one of the most intense white-water experiences in the country within easy reach of Kathmandu. It is best for fit, confident rafters, with milder lower sections for keen beginners.
Overview and difficulty
Graded IV to V, the Bhote Koshi has one of the steepest gradients of any rafted river in Nepal. The water is fast, technical and almost non-stop, with big drops and tight lines that demand quick, coordinated paddling. The exact difficulty swings hard with water level: lower flows give cleaner, more readable rapids, while high autumn water turns it into a serious expert run.
Length, days and access
This is a one-day river. The rafted stretch is short, roughly 8 to 12 km, but the relentless gradient means you are working almost the whole way. The put-in is in the upper valley near Barabise, with take-outs further down toward the Sun Koshi confluence. The river lies around three to four hours northeast of Kathmandu near The Last Resort, so many trips combine rafting with bungee jumping and canyoning at the same base.
Season
Run it in spring (March to May) or autumn (October to November). Lower or moderate flows give the best balance of excitement and control; the highest autumn water is for experts only. The monsoon makes the river unrunnably high and dangerous, and winter is cold with low flows.
What to expect
After a thorough briefing and practice in flat water, you launch straight into the action. The rapids arrive in quick succession with little recovery time, so focus and teamwork matter more than on easier rivers. A safety kayaker usually accompanies the raft. The steep, jungle-walled gorge and the constant white water make for an exhilarating, fast-moving day.
Operators and safety
Because the Bhote Koshi is demanding, operator quality is critical. Choose a company that provides self-bailing rafts, helmets and life jackets, an experienced river guide, and a safety kayaker on the harder sections. Be honest about your fitness and experience, listen carefully to commands, and never run the upper river with a budget operator cutting corners.
Tips
- Build up to it: raft the easier Trishuli first if you are unsure.
- Book the bungee-and-raft combo at The Last Resort to make the trip worthwhile.
- Go on a moderate water day for the best mix of thrill and control.

Frequently asked questions
What grade is the Bhote Koshi River?+
The Bhote Koshi is graded IV to V depending on the section and water level, making it one of the steepest and most continuous commercially rafted rivers in Nepal. The upper section is the most demanding; gentler stretches lower down can be run by fit beginners with a strong guide.
How long is a Bhote Koshi rafting trip?+
It is usually a one-day trip. The rafted sections are short, around 8 to 12 km, but the gradient is so steep that the rapids come one after another with little rest, so a short distance still makes for an intense day on the water.
Where is the Bhote Koshi and how do you get there?+
The Bhote Koshi flows from the Tibet border down toward the Sun Koshi, around three to four hours northeast of Kathmandu near the village of Barabise and The Last Resort. Most operators run it as a day trip or a combo with bungee and canyoning at the resort.
When is the best time to raft the Bhote Koshi?+
Autumn (October to November) and spring (March to May) are best. Lower spring or post-monsoon flows give the cleanest lines, while very high autumn water makes the river extremely powerful and is for experts only. Avoid the monsoon, when the river floods.
Is the Bhote Koshi suitable for beginners?+
Not the hardest sections. The steep upper Bhote Koshi is for confident, fit rafters and is often Grade IV to V. Some operators run a milder lower section for first-timers, but if you have never rafted, the Trishuli or Seti are far better starting points.
