Sun Koshi River Rafting offers the longest trip in Nepal in terms of river days. It has many tributaries entering from the north that drain Himalayan peaks including the mighty Mount Everest. The character of the river changes with amazing wide valley sections and large sandy islands becoming narrow jungle gorges and corridors. There is only one large village on the river, the hardest rapid – Hakapur is named after Sun Koshi. The upper section is known as the Bhote Kosi, an adrenaline-charged section of the river described separately in this guide.
The commercial trips start at Dolalghat, which is close to the confluence of the Bhote Koshi, and the Indrawati. You can expect the trip to take 10 days; this may include a layover day. It takes 8 days in total to raft Post monsoon, 6 in a kayak. We start our trip from Kathmandu and drive to Dolalghat which is the put-in point of this rafting.
