Sun Koshi River Expedition

Sun Koshi River Expedition – A Premier Whitewater Rafting Adventure in Nepal

The Sun Koshi River ranks among the top 10 whitewater rafting rivers in the world. It offers an unforgettable multi-day river expedition. This adventure combines big volume rapids, warm water, and breathtaking Himalayan scenery.

The Sun Koshi River Expedition is ideal for intermediate and advanced rafters. It also suits experienced kayakers during medium to high water flows.

The name Sun Koshi means “River of Gold.” The river originates near Tibet and joins the Bhote Koshi River downstream. Navigate Outdoor’s expedition starts at Dolalghat and ends at Chatara near Dharan.

The journey covers 270 kilometers. It takes 7 days in September’s high water. It extends to 8-9 days in October and 9-10 days from November to December.

The river flows from near Kathmandu to eastern Nepal. It carves a fertile valley where locals grow maize, rice and wheat. This makes it one of Nepal’s premier whitewater rafting destinations.

How Sun Koshi is Created:

The Sun Koshi watershed is fed by Himalayan glaciers. These streams stretch from Ganesh Himal to Kanchenjunga, the world’s third highest peak.

Rapids change every year due to monsoon debris and rockfalls. Most rapids are thrilling and runnable. Key rapids include No Exit, Harkapur II, Jaws, Rhino Rock and Big Dipper.

Navigate Outdoor emphasizes safety and risk management. Our expert guides continuously assess conditions and communicate clearly with clients.

During low flow seasons, the Sun Koshi River is perfect for kayakers. It helps them improve skills and progress toward professional guiding.

Navigate Outdoor also runs annual guide schools and kayaking courses. Contact us for upcoming dates and details.

For extra adventure, we offer optional trips on the lower Tamor River. This section features continuous Class 3-4 rapids. It shares the same take-out point as the Sun Koshi River.

The Tamor River originates near Kanchenjunga. It adds a majestic Himalayan backdrop to your paddling experience. This Sun Koshi River Expedition pairs perfectly with Nepal trekking adventures like Everest Base Camp trek, Annapurna Circuit trek or ABC trek.
