Sun Koshi is one of the longest rivers in Nepal. This trip starts near the Tibetan border and as the river flows down South it is fed by several rivers off the Eastern Himalayas, which changes the river regularly from wide valley and beaches to narrow gorges. Sun Koshi streams all the way down to the sacred Ganges in India. On the way you will see canyons, waterfalls, temples and white sandy beaches where you will camp. This trip garanties a great variety of whitewater and sceneries and is one of the top ten rafting trips in the world!
Note: During spring season we skip the first three days and start at Harkapur instead. The price will be accordingly. For more information please contact us
We leave early in the morning for a 3-hour drive out of Kathmandu valley to Dolaghat. If the weather is clear, you will have amazing views on the way. Once arrived at the put-in point we inflate the rafts, tie all the equipment on the raft and prepare a big lunch. When all the preparation is done everyone gets a lifejacket and helmet. Then the raft guide and safety kayaker give an extensive safety briefing, explaining about sitting position, paddling techniques and what to do when you fall out from the raft. After lunch we leave the roads behind for the next 8 to 9 days.
Below the suspension bridge at Dovan Tarr the river enters a small canyon with waterfalls. As the canyon opens up, you will see a large bat cave. We will try to get close, but try not to disturb them. Later on you will arrive at a Shiva temple, where you can wander around for a while.
While you raft down the Sun Koshi river, the guides explain more about how to paddle through whitewater and stay in the raft while it moves through the rapids. The guides will also teach you what they are looking for when they run the river – the rise in the water that hides a hole, or the way you can use the water rebounding off a rock to steer the raft where you want it. By the time we get to the harder rapids (like Meat Grinder, High Anxiety and Harkapur 2) you will all be perfectly working together as a team. The rapids change from year to year depending on the severity of the monsoon rains.
After stopping at Tokshel, Harkapur and spending some time there we go down to Harkapur 2. Right before the rapid we pull over to camp. You can walk down a bit and look at the rapid and contemplate the start of the next day.
Harkapur 2 is a very interesting rapid, with rockfall on one side, a big mudslide on the other side and big holes in the middle of the river. There are much more rapids to come. A few kilometers down we’ll find the Dudh Koshi (‘the river of milk’), which is a lot colder than the Sun Koshi. Below the next suspension bridge is a small rapid, followed by Jaws and Dead Man’s Eddy. In the rock wall on the left-hand side is a huge eddy that has the reputation of collecting anything that floats away. You camp just before Jungle Corridor. The Jungle Corridor is a wild section of rapids like Rhino Rock. At the end of the Corridor are a series of waterfalls, so prepare for a shower.
By the Sun Koshi river are many beautiful white sandy beaches, which are ideal to camp on. There is at least one lay-over day where you stay at the same camp 2 nights. Here you can relax or undertake some beach activities or trek to a nearby village.
The last big rapid of this trip is The Big Dipper, also called the Quick Stripper, so make sure everything is tightened. After this rapid it’s a quiet cruise down to the confluence with Arun and Tamur and the beginning of Sapta Kosi (the seven rivers). Here is an interesting temple to visit, where every year on the day of full moon in January, thousands of Hindu pilgrims come together to pay homage to Lord Vishnu. Just a little further downstream lies India. By afternoon we reach the take-out point where we will clean and break down everything and load it on top of the bus. From here it’s a 15-hour drive back to Kathmandu where we arrive early in the morning. If you don’t want to go by bus, there is also an option for a 45-minute flight from the nearby town Biratnagar to Kathmandu at your own cost.
