Bhotekoshi River Rafting – 1 Day

This is a day trip with no overnight stays involved. Pick-up is arranged from your hotel in Kathmandu (typically in or around Thamel) or from our office in the early morning, and you are returned to the city by early evening. For those wishing to add the nearby 160m bungee jump, canyon swing, or a night at a riverside resort, we can arrange a two-day program with an overnight stay in the gorge.

Bhotekoshi means “the river from Tibet” in Nepali, and the river descends directly from the Himalayan border at Kodari, following the line of the ancient Kathmandu-Lhasa trade route that is today the Araniko Highway. For centuries this corridor carried salt, wool, and grain between Nepal and Tibet, and the river valley remains one of the most historic in the country.

Commercial rafting reached the Bhotekoshi in the 1990s, when Nepal's pioneering river companies pushed beyond the Trishuli in search of steeper water and quickly recognized the upper gorge as the most intense raftable run in the country. The river has since weathered dramatic events, including the 2015 earthquake and subsequent floods that reshaped parts of the valley, yet it remains the benchmark against which every adrenaline-seeking paddler in Nepal measures a day of white water. Today, its short, steep run and quirkily named rapids enjoy near-legendary status among rafters and kayakers worldwide.

The Bhotekoshi rises on the Tibetan plateau and crosses into Nepal at Kodari, cutting a deep, narrow gorge south through the Sindhupalchok district before merging into the Sunkoshi near Lamosangu. It is the upper reach of the great Koshi river system that ultimately drains much of eastern Nepal. The commercially rafted section drops at roughly ten times the gradient of the lower Sun Koshi, squeezing continuous Class III-IV rapids into a short stretch of boulder-choked river between steep, jungle-clad walls.

Major Geographical Highlights

•         The Bhotekoshi Gorge – a deep, narrow canyon of cliffs, waterfalls, and dense green hillsides carrying the river down from the border.

•         Class III-IV Rapids – an almost continuous staircase of technical white water, including the famous Frog in a Blender and Gerbil in the Plumbing.

•         Araniko Highway – the historic Kathmandu-Lhasa trade route that follows the river, providing easy road access to the whole run.

•         Kodari / Tatopani – the border area at the head of the valley, known for its hot springs and Friendship Bridge to Tibet.

•         The 160m Suspension Bridge – site of one of the world's highest bungee jumps and canyon swings, spanning the gorge near the river.

•         Lamosangu – the take-out area where the Bhotekoshi feeds the Sunkoshi, gateway to the great rivers of eastern Nepal.

The Bhotekoshi is a steep, technical, high-consequence river, and it demands the very best in professional river leadership. Every raft is captained by a senior, government-licensed guide, and safety kayakers accompany every departure.

•         River Safety – guides read the fast, technical water, scout key rapids, and choose the safest lines through every drop.

•         Expert Instruction – an extended paddle-training session ensures every crew responds instantly to commands where split seconds matter.

•         Safety Kayakers – expert kayakers shadow the rafts through every rapid, positioned to assist swimmers within moments.

•         Rescue Training – all guides are trained in swift-water rescue and first aid, with throw ropes and rescue equipment on every raft.

•         Water-Level Judgment – guides assess the river daily and adjust the put-in, program, or timing to match safe, enjoyable conditions.

A freshly prepared lunch is served riverside after the run, prepared by our crew with hygiene as the top priority, and it always tastes better with a healthy dose of post-rapids adrenaline.

Typical Lunch Options

•         Sandwiches, fried rice, or noodles with fresh vegetables

•         Seasonal salads and fresh fruits

•         Eggs, potatoes, and light snacks

•         Tea, coffee, and juice

Safe drinking water is provided throughout the day. Breakfast and dinner are not included, allowing you to eat at your own pace in Kathmandu before departure and after your return.

The Bhotekoshi is a genuinely challenging river, and while our safety systems make it a well-managed adventure, participants should understand that this is a step up from gentle introductory rafting. The main considerations relate to the power of the water, the cold glacial temperature, and physical readiness.

Key Safety & Health Points

•         High-buoyancy life jackets and helmets are worn at all times on the water, and wetsuits are provided year-round for the cold glacial water.

•         Basic swimming ability and confidence in moving water are strongly recommended for this river.

•         Listen carefully during the extended safety briefing and respond instantly to your guide's commands in the rapids.

•         Be honest about your fitness, experience, and any medical conditions when booking; the trip is not suitable during pregnancy or for those with serious heart or joint conditions.

•         Sun reflects strongly off the water; use waterproof sunscreen and secure sunglasses with a strap.

Safety kayakers accompany every trip, a first aid kit and full rescue equipment are carried on every raft, and the highway beside the river allows rapid access to medical facilities if ever needed.

Autumn (September-December)

•         Post-monsoon flows gradually dropping from powerful to playful

•         Warm, stable weather and superb gorge scenery

•         The most popular season for the Bhotekoshi

Spring (March-May)

•         Rising snowmelt brings the rapids back to life after winter

•         Warm days ideal for getting splashed

•         An excellent second season for the river

Winter (December-February)

•         Lower, technical water levels and crisp, clear days

•         Cold glacial water managed comfortably with the full wetsuits and splash jackets we provide

During the monsoon (June-August), the upper Bhotekoshi rises to dangerous levels and commercial trips on the steep section are suspended; our team assesses water levels daily in every season and always errs on the side of safety.

Commercial rafting on the Bhotekoshi requires rafting permits arranged through the relevant authorities, and all trips must be led by licensed river guides. Permit fees are set by the Nepal government and local authorities and may change periodically; all permits are arranged by our office in Kathmandu, so you simply need to bring yourself and your sense of adventure.

•         Swimwear or quick-drying shorts and a t-shirt to wear under the wetsuit

•         Secure sandals with heel straps or old sneakers (no flip-flops)

•         A full change of dry clothes and a towel for after the trip

•         A warm layer for the drive home, especially in autumn and winter

•         Waterproof sunscreen, lip balm, and sunglasses with a retaining strap

•         A waterproof camera or GoPro with a secure mount if you wish to capture the action (optional)

•         A small amount of cash for drinks and snacks en route

This trip is graded moderate to challenging and is aimed at fit, adventurous participants. No previous rafting experience is strictly required, but you should be in good general health, physically active, comfortable in water, and ready to paddle hard on command for sustained bursts. Basic swimming ability is strongly recommended. The minimum recommended age is around 15-16 years, and participants who have enjoyed the Trishuli and want the next level will find the Bhotekoshi the perfect step up. If you are unsure whether the river suits you, our team is happy to advise honestly based on the season and water levels.
