The Sun Kosi is one of the longest river trips in Nepal and will take you on a stunning river journey across Nepal, from the rushing torrents of the high mountains to the calm of the Gangatic plain. So if you want an adventure of a lifetime, rafting one of the top ten river journeys in the world, then this is the river for you!
As the Sun Kosi flows southward it is fed by several rivers entering from the North that drain Himalayan peaks including the Mount Everest. The confluences of the rivers regularly change the character of the river from amazing wide valley sections and large sandy islands to narrow jungle gorges and corridors.

On average you can expect the trip to take 9 days, however we can tailor this trip to your requirements, adding extra rest days or excursions to nearby villages. Post monsoon (Oct-Nov) it can be rafted in 8 days, or kayaked in 6 days The river starts with easy rapids and builds up to a climax at about the halfway point. From there it remains at a good level through the jungle corridor after-which, it flattens considerably before a final adrenaline hit at the Big dipper (4).
From the first day you encounter big and bouncy wave trains at class 2-3 and then the excitement starts as you reach the Meat-grinder rapid (4-) close to the confluence of the Tamba Kosi. From here class 3+ to 4- is the order of the day, with some rapids like High Anxiety (4-) which are just massive surf waves during early October descents.
The Hardest rapid Hakapur (5-) is just before the halfway point and often a lay-over day follows at Little Devisthan beach. Below here the Dudh kosi enters and the river narrows into the jungle corridor – Imaginative names of rapids within (Rhino rock, No Quiche, Dummy to the wall, Roller coaster & El Wasto!)
The river continues with several more rapids at a lower grade. The Arun and Tamur rivers join just before the Sun Kosi breaks out of the valley it has been held in for 270Km, and flows into the vastness of the Gangatic plain taking it eventually draining into the Bay of Bengal.
