This is the longest
river trip offered in Nepal, traversing 270 kms through the beautiful
Mahabharat Range on its meandering way from the put-in point at Dolalghat
to the take-out point at Chatara, far down on the Gangetic Plain. It is quite
an experience to begin a river trip just 3 hours out of Kathmandu, barely
60 kms from the Tibet border, and end the trip looking down the hot,
dusty gun barrel of the North Indian plain just a week later.

The Sun Koshi starts
off fairly relaxed with class II and small class III rapids to warm
up during the first couple of days. Savvy guides will take this
opportunity to get the teams to work with exquisite precision as on
the third day, the rapids become more powerful and frequent with high
water trips. One can be astonished at just how big a wave in
the river can get. While the lower sections of large volume rivers are
usually rather flat, the Sun Koshi reserves some of its biggest and best
rapids for the last days. At the right flow, it is an incredible combination
of powerful whitewater, stunning scenery, villages and truly quiet
and introspective evenings along what many people consider to be one
of the world's ten classic river journeys.
"An absolutely fantastic trip. All the guides were excellent. I will certainly recommend the company. The best rafting experience this side of the milky way! "
