About Sun Kosi River , Trek and Tamur River Rafting/Kayaking Trip

Sun Kosi (River of Gold)

If you want to tick off your bucket list with the Sun Kosi expedition as one of your rivers to paddle then why shouldn’t you?  It’s great fun, bouncy and has exciting rapids.

*Beautiful beach camping

*Pass through remote villages, jungle and waterfalls

*It is Nepal’s original river expedition

The Sun Kosi is the longest trip in river miles offered in Nepal and is rated as one of the top ten river expeditions in the world.

Starting near the Tibetan border and draining off the Eastern Himalayas all the way to the sacred Ganges River in India, this river offers big volume whitewater. A journey down this “river of gold” impresses any rafting or kayaking enthusiast with relaxing and sometimes challenging canyons, refreshing waterfalls, bat caves, interesting temples, beautiful white sandy beaches for setting up camp and of course a great variety of whitewater.

If you are looking for a long river expedition with a nice variety of scenery and access to villages along the way, then the “river of gold” is a classic choice.

Adventure Hub Nepal (AHN) also offers lots of trips with different combinations and durations on the Sun Kosi so please ask our friendly office staff about the choices you can take if you are on a tight schedule.

Tamur River 

This is probably the best multi-adventure trip in Nepal, if not the world! Our journey starts with 3 days trekking following a 3000-meter ridge through woods and meadows taking in stunning views of Kanchenjunga, Makalu & Mount Everest before dropping off into the lush villages of the Tamur Valley.

Once we hit the river, this amazing whitewater adventure starts out with a bang with some big, intense and challenging class 4+ rapids. The rest of the river is an exciting combination of white water and beautiful remote wilderness scenery.

If you would like to get completely off the beaten track and seek an authentic travel experience and personal challenge, then this trekking and whitewater combination is a perfect epic adventure for you. This trip is for one who likes to enjoy mountain views as well as do great whitewater rafting or kayaking adventures.


This is the easiest of our moderate level lodge and tented trekking adventures and may involve walking for up to 6 to 7 hours per day.  Maximum altitude is 3,000 meters and as the trek involves three days walking a total of approximately 45km a good level of fitness is required.  The first day is a big day and we hope to cover a good distance on gently ascending and level hilly terrain on well-defined trails.  On the second day, we start descending on well-defined trails that are steep and rocky in places. The last day is a half-day trek covering approximately 8 kilometers over mostly descending, somewhat steeply in places, well-defined trails.

Note: It's possible to do the Sun Kosi expedition only or Trek & Tamur river only for people who don't have enough time for the whole trip. Just send us an email and we can design itinerary according to your needs.

Fixed Departure : 7th - 25th Nov 2023/24

Alternatively, pack some gear for the bus taking us to Basantapur which is the starting point for the trek.  After organizing all of this, we will go for a traditional Dhal Bhat lunch.

With the truck and the AHN staff taking all our gear to Dobhan it means we can travel light on the trek.  You just have to carry what you need for the 2 night 3 days trek – Drink bottle, Thermarest, sleeping bag, minimal clothing, medication, etc. – we will have porters to help as required.

After lunch, drive approx. 5.5 hours to Basantapur which is the starting point for the trek and stay the night in a lodge.

Stay in a tea hut overnight.  It’s a full day today, expect to walk for 6-7 hours gradually gaining height and then leveling out - you will reach the top of the ridge at 2,980 meters – expect to cover approx. 26km today.

Today you will continue trekking along the ridge through picturesque rhododendron forest and enjoy the spectacular views.  The path winds gently up and down through ancient moss-covered trees.  We then start to descend – steeply in places - and after approximately 5 to 6 hours arrive at our stopping point.

The Tamur River flows from the mighty Kanchenjunga mountain which is the third highest peak in the world.  This trip combines fantastic whitewater and one of the most beautiful short treks in Nepal.  It has spectacular views of Mt. Everest, Kanchenjunga and Makalu as you traverse along a ridgeline at over 2,800 meters - 3 days trekking and 6 days rafting/kayaking.

The river is a beautiful turquoise color and each day there are big volume rapids of class 3-4/4+.  The river starts with a bang with 2 days of big volume class 3 to 4/4+ rapids.  It then eases in the middle for a day or so with enough white water to keep you interested.

It then finishes with 2 days of amazing class 3 to 4/4+ rapids – more rapids than you can count down to the confluence with the Sun Kosi.  Camping is on beautiful sandy beaches along the river and there is plenty of time for exploring and beach volleyball.

The last day of whitewater rafting and kayaking on the Tamur will take you down to the confluence of the Tamur and Sun Kosi Rivers.  Over 30 rapids, of fun class 3 and 4/4+ white-water make this a fantastic day of paddling.  Camp at the confluence of the Tamur and Sun Kosi Rivers.

Paddle down to the take-out of the Sun Kosi river at Chatra stopping along the way at the Bharah temple.  Lunch in Chatra and then overnight bus trip back to Kathmandu approximately 16 to 18 hours arriving at approx. 7 am the following morning. 

NB: There is the option to take a 35-minute flight back to Kathmandu from Biratnagar which will cost approx. an additional US$ 250.  Biratnagar airport is about an hour’s drive from the take-out at Chatra.  The cost of the flight, an extra night in Hotel in Kathmandu, transport to Biratnagar airport and from Kathmandu airport to Hotel is all extra.  If you are interested I am doing this, please let us know so as we can give you latest cost estimate.
