THE SUN KOSI RIVER (9-10 days)
Best time : September to December and March to May

It 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 it.

The upper section is known as the Bhote Kosi, an adrenaline charged section of river described separately in this guide. The commercial trips start at Dolalghat, which is close to the confluence of the Bhote kosi, and the Indrawati.
You can expect the trip to take 10 days; this may include a layover day. Post monsoon it can be rafted in 8 days, 6 in a kayak.
