The Trishuli is Nepal’s most popular rafting river. It has impressive gorges, moderate white water, a few exciting rapids, some easier sections, all easily accessible from Kathmandu and Pokhara. Popular also with kayakers as an easy access ‘play river’ and as a warm up for big water. Not however, that the proximity of the main highway and the popularity of the river may detract from the experience.

The River

Legend says that high in the Himalaya at Gosainkund  the god Shiva drove hios trident into the ground to create three springs – the source of the river and hence its name Trishuli.
Not far after this source the Trishuli joins the Bhote koshi that flows from Tibet; the two rivers joining in some pretty fearsome looking gorges that are visible on the way up to the Langtang trek. By Betrawati the gradient has eased and after this it becomes a more mature and powerful river which later adds many other major rivers to its flow – the Buri Gandaki, the Marshyangdi, and the Seti. When the Kali Gandaki Joins it, shortly before the plains, it changes its name to the narayani. Here, it is a truly mightly river – peak flows in the Monsoon have been measured at 25,700 cumes (extreme, instantaneous discharge);  about 900,000 cfs or fifty times the typical flow of the Colorado River through the Grand Canyon!

Normally the flow on the main rafting  section of the Trishuli is about half that of the grand Canyon, and in many ways the rapids are smaller scale versions of those on the Colorado, they are formed mainly by boulder outwash from tributary streams and are characterized by big green shoots, holes either side, and huge exploding waves down the bottom.
