Sun Koshi River Expedition  

Length: 11 days      Level: Intermediate.     Suitable: All level rafters. Intermediate kayakers.
Option: Return flight to Kathmandu (trip becomes 10 days).

Paddle this iconic Himalayan river, an awesome self-supported expedition 280 km across the country, through varied lanscapes and some of our best white water! 

On this fantastic 11 day river expedition we are completely self-supported – carrying what we need in our rafts. We paddle through great white water and set up camp on a new beach every night, packing and cooking together as one team. This is the trip is for paddlers who are looking for great fun on a big volume river and are ready to push the adventure to a new level!

DAY 1: We pick you up in Kathmandu in the morning and drive a couple of hours to Dolalghat – our river starting point of the Sun Koshi. The drive is spectacular with magnificent views of the Himalayan Ranges on a clear day. Upon arrival at Dolalghat we unload gear, learning how to set up our camp for the night and have dinner served.

DAY 2: Our first day on the river! After breakfast your expedition leader will give you the full safety briefing for the trip before we set out on the river. 

We paddle our first stretch of easy class II water with occasional class III rapids - a perfect warm up day. We find a nice beach to set up our camp for the night. 

DAY 3: After breakfast we pack up the gear and start rolling down the river. Today you will encounter a big water class 4 rapid “The Meat grinder”. It is a fairly straight run down the centre. Round the corner the Tamba Kosi river is joining from the left. We camp on the perfect beach on the confluence. Right next to the camp there is a Shiva temple.


DAY 4: We start the day with an easy drift in the morning and after lunch we punch a few good rapids. There is one more river joining here, the Likhu Khola. A few kilometres after the confluence we go through a long class 4 rapid called “High Anxiety”. After a couple of more hours of paddling we look for a camp on the beach.

DAY 5: Today starts with several class 3+ rapids before we arrive in Harkapur, a small village right by the river. At this point we have done half of our journey. Right after the village there is one of the hardest rapids on the rive, “Harkapur II”. We scout the rapid and shoot right down the middle.

A few kilometres below “Harkapur II”, the mighty Dudh Kosi River (the river draining from Mt. Everest) joins the Sun Koshi. Now the volume of the river is about three times more then on the first day. We paddle a couple of more hours down to Rai Ghat a small village on the river left and camp.

DAY 6: Below Rai Ghat we meet some small rapids leading to bigger ones, like “Jaws” and “Dead Mans Eddy”. After doing the harder rapids we have couple of hours of easy drift before arriving to “Rhino Rock”. We punch “Rhino Rock” and enter the “Jungle Corridor”. We camp in the jungle tonight and save the hard water for the morning.

DAY 7: Today is an exciting day as you will encounter the “Jungle Corridor” a continuing white water sections of class III-IV rapids. At the end of this section we arrive at the waterfall beach where we do a lunch break and take a short walk to the waterfall for a shower. Afternoon drift down to the next camp.


DAY 8: We take a full day of much needed rest on the beautiful beach. Settle in, read a book or go explore the jungle and small villages in the area. 


DAY 9: Now we have a few more rapids left on the last stretch of the river bringing you to the last class IV rapid “The Big Dipper” with a series of huge standing waves. After this rapid the river mallow out and you will arrive at the Arun and Tamur River confluences. These two rivers make the Sun Koshi change name into the Sapta Koshi. It´s our last night camping on the river journey.

DAY 10: A couple of hours drift on the Sapta Koshi in the morning, and we stop to visit an old Hindu temple at Braha Chetra. We arrive in the lowlands, Terai, and the hills dramatically opens up in to the Indian plains. Your classic and memorable river journey will end at Chatara.

We pack up and start the drive back to The Royal Beach Camp through the southern parts of the country.

Here you have the option to return directly to Kathmandu by a short flight (we can help arrange this).

DAY 11: We arrive back in the morning, in perfect time to be served a nice breakfast. Say good bye to the great team and friends before taking the bus back to Kathmandu.
