Sunkosi River Expedition

Based on 5 Reviews

One of the ten best whitewater rafting trips in the world. Big Rapids warm water, beautiful scenery and great camping make this a classic multi-day river trip. A great trip for intermediate and advanced kayakers. At its best in medium to high flows.

Sun Kosi means “River of Gold” – perhaps named after the gold that is sometimes panned from the river gravels;  or alternatively, it refers to the orange color of the water in the monsoon when it is thick with alluvial silt. The river rises near Tibet and joined by Bhote Kosi just downstream from Barahabise. Most raft trips start below here at Dolalghat. Navigate Outdoor we start our trip from Sukute which is 10 extra KM to the Dolalghat.

The Sun Kosi flows eastwards in Nepal through the great valley between the Mahabharat Mountains rage and the Himalaya. It forms the watershed for most of eastern Nepal and gathering strength from tributaries draining the highest mountains in the world it emerges onto the northern plains of India where it joins the Ganges.

This is a large volume river where most of the major rapids are formed by monsoon debris brought in by side streams and loose rock fall so the rapids change from year to year depending on the severity of the monsoon. One of the nice things about the Sun Kosi is that, with the exception of a few big rapids like Harkapur –II ( that can be walked around if wanted). Some the rapids we do land scout and discuss with our clients before we run them like; No Exit grade 3, Harkapur –II grade 4+/ 5, Jaws grade 4 ; Rhino Rock grade 4, and big dipper grade 3-4 ; they several rapids they can flip your raft anytime anywhere some time wire pool makes your raft flip which is on the flat water section in between jungle corridor and waterfall beach.

During the low flows will be perfect for those who want to learn guide and progression on Kayaking. Navigate Outdoor organize guide school/ kayaking learning opportunity for the adventure enthusiastic every year please contact us info@navigateoutdoor.com  for more details and date.

Karnali River Experience.

They say that the journey is better than the destination. That all the experiences along the way are like an accumulation of rocks along a riverbed. This story is another stone in a river.

I have known Mani Aryal for several years, meeting him in the United States, in the state of Utah. Mani and I were both on a work contract to take a group of students down Desolation & Grey Canyon on the Green River. After spending three weeks with Mani I knew that I made a paddling adventure buddy and that he would be a person that I actively stay in contact with. The years have a way of floating by with adventure and intentions. Every time I spoke to Mani he persistently invited me to Kathmandu to see his home and to float the rivers. Three years after saying “no”, I finally could say “maybe”.

Kathmandu is large in legend and small in structure. The shuttle ride from the airport is an example of whitewater: dodging potholes, must-make moves, and pure adrenaline. It’s best not to watch.

There are two options to get to the river when signing up for a Karnali River Expedition trip: 1) take the plane or 2) ride with the guides and gear on public transport. I was on a tight budget, so option #2 was the only way to go. Putting together a multiday river trip is always difficult, especially when you start combining buses, shuttles, and rendezvous. The first leg of the journey was via public transportation to Koholpur. The guides and I, hanging out at the main bus depot, loading all of the gear we would need for the next 12 days was a new experience indeed.

You see a lot of different people and livestock on the long distance buses. Chickens and goats are not uncommon. If a woman is standing with a baby, it’s a norm to hand a baby to you, a seated passenger, to hold the child in order to give her a break.

The second half of the shuttle was a private bus to the put-in, the small village of Dungeshor that is located straight down a canyon. The route our bus driver picked was shorter to save fuel but longer because of road conditions. Our bus rocked, creaked and moaned down the road for 8 hours only to cover 85km. “Singletrack” may be a better description than “road” as there were only inches to spare between rock walls and open air.

 Sideswiping other buses, scouting rock gardens and pushing our transport were common occurrences that quickly become norms. We reached Dungeshor after 10 pm to hastily inhale some food and beer from a generous restaurant owner who opened his doors after hours. Afterward, we set up our tents on the riverbank to welcome a solid, unwavering piece of ground to usher in some sleep.

The next morning, the guides were in their prime, having already started getting breakfast ready for everyone. Mani was no exception, greeting me with a great, white smile and a coffee to help orient my mind back to my body. The biggest surprise was all of the children hanging about camp. We were all warned not to leave our gear unattended. Later that day, I realized a carabineer walked off to hang out with the children. The guides seemed to include me that much more by laughing and sharing stories of gear gone lost.

Throughout the six days, Mani and his guides were exceptional hosts. It seemed as if they never stopped moving. Always quick to put a coffee in your hand, help you set up your campsite or to offer a meal. Every morning they would barter with local fisherman to add extra flair to the menu. On the water, I felt safe and involved in the risk management. All ideas were heard until a plan formed to be implemented with everyone on board. The standard followed by Mani was professional.

Six months after this trip, the strongest memories I have are of traveling to and from the river. Once I had oars in my hand and a blue sky above me I knew who I was and how I got there.

The total trip duration from Kathmandu to Kathmandu was 10 days included bus journey.

Thank you, Mani. I look forward to our next adventure.
