SunKoshi is Nepal’s largest-volume whitewater river and one of the great expedition classics of the Himalayas. It is best known as a premier destination for kayaking and rafting in Nepal. Starting from Harkapur, the journey covers approximately 155 km of powerful flows, long wave trains, and open valleys. Life unfolds along the banks villages, temples, farmland, and wide sandy beaches that become our camps each night.
This is a river defined not just by whitewater, but by culture, space, and rhythm. We experience big days on the water, quiet evenings on golden beaches, and a deep sense of what rafting in Nepal truly means. The SunKoshi is widely acknowledged as one of the ten best rafting trips in the world, offering powerful rapids, warm water, and a true wilderness experience.
The journey begins with a scenic drive from Kathmandu towards the Everest Base Camp route (approx. 5-6 hours) to the put-in at Harkapur. After safety briefings and on-land training, you launch into the river’s rhythm. The expedition features the sharp, technical “Harkapur II” rapid (reshaped by a 2023 flood), long wave trains, big volume whitewater, and a relaxed “flow day” where you simply drift and soak in the surroundings. The expedition concludes with a temple visit, a BBQ farewell dinner, and a scenic flight back to Kathmandu.
The SunKoshi Expedition is not merely about rafting a river; it is about experiencing one of the world’s great whitewater journeys where the water, the culture, and the wilderness come together in perfect rhythm. It is a once‑in‑a‑lifetime adventure that demands preparation but offers rewards that last forever.


Activities: Early departure from Kathmandu via the highway leading toward the Everest Base Camp route (approx. 5-6 hours drive). Upon reaching the river put-in, the group sets up camp. Essential safety briefings, gear checks, and on-land training. Camp by the river.
The day starts with the "Harkapur II" rapid, described as a sharp, technical rapid (reshaped by a 2023 flood). The rest of the day features fun, friendly whitewater. Falling into the rhythm of the Sunkoshi.
Long wave trains, big volume whitewater, and a feeling of being far from everything. A campsite that feels "off the map."
A relaxed day easing into the natural rhythm of the river. Relaxed floating mixed with pockets of playful whitewater. No rush, no noise.
Rise early, paddle for one hour, and visit one of the most important temples in Hinduism. Then paddle through a few big wave trains. Late lunch, followed by settling into a "cosy riverside safari tent resort." The crew hosts a BBQ for the last night together by the water.

World-Class River Leadership. Special Forces Logistics. One Team. One Mission. One River.
At Himalayan Outdoor Project, every expedition is a collaboration between two extraordinary minds. Anup Gurung, your Expedition Leader and world-class kayaker, has conquered the world’s most extreme waters from the frigid rivers of Iceland with Viking Rafting to the raging whitewater of the Himalayas. An IRF instructor, solo paraglider, and enduro rider, Anup brings an unmatched depth of river intuition, technical mastery, and sheer passion for the water. He doesn’t just guide he lives for the river.
Behind every expedition is Ex. Special Forces Maj. Rajiv Chand, the architect of logistics and safety. A retired Major from the Nepali Army Special Forces with over 20 years of field experience in navigation, leadership, and decision-making, Rajiv ensures that every detail from route planning to emergency contingencies is executed with military precision. His systems turn wilderness adventures into professionally managed operations where nothing is left to chance.

PLAN. PREPARE. EXECUTE. RETURN SAFELY.
Successful SunKoshi expeditions begin long before arriving at the river and they end only when every paddler is safely home.
PLAN
Every detail matters – Route | Logistics | Weather | Water levels | Equipment | Contingencies | Emergency response. Nothing is left to chance. The 155km journey through remote valleys requires precise planning and careful river management.
PREPARE
Preparation creates confidence. Every paddler receives guidance on: Physical training | Paddling techniques | Safety protocols | Equipment selection | Nutrition and hydration | Mental preparation for the river challenge.
EXECUTE
On the river conditions constantly change. Our team adapts, communicates and makes informed decisions based on: Water levels | Weather | Team health | Individual performance | Safety considerations.
RETURN SAFELY
The take-out is only halfway. Our objective is simple: Bring every paddler home safely. Safety First. Adventure Second.
Most expeditions start in Kathmandu. Ours starts months before.
Physical Preparation
