Arun River is expected as one of the most mighty and powerful rivers of Nepal originated from Tibetan Plateau to the north of Kathmandu and it then swings in an eastern arc for some 200 km. Drinking the Northern slopes of Everest and Makalu before cutting south through the Himalayas and into Nepal. The gorges and gradient ease off near Chandanpur as the valley open out and the hill gets lower. L. R Wager, a mountaineer, and geographer explored these gorges on the upper Arun. In more recent years, the river has been the subject of a run 3, a proposed huge hydroelectric project that thankfully has now been shelved.
Arun River and its tributaries drain a huge watershed and the river carries a huge load of sediment and glacial silt whch is best for rafting. Colour varies between a milky brown to a granny. The deep gorge of the upper river of Arun have a granite canyon clad in the overhanging jungle and are a wild variety of plants and animals life very beautiful but at times damp and gloomy which make Arun River rafting more exciting.
