Trisuli River in Rasuwa
|- location||Gosaikunda, Rasuwa, Nepal|
|River system||Narayani River|
The Trishuli is named after the trishula or trident of Shiva, a powerful god in the Hindu pantheon, There is a legend that says high in the Himalayas at Gosaikunda, Shiva drove his trident into the ground to create three springs – the source of the river and hence its name Trisuli.
The stream in Tibet crosses the Nepalese border at Gyirong Town, with the Kyirong gorge opens out at Ragma (3000 m). Thereafter, it flows through Nepal and joins at Devghat the Narayani River, which at a lower stage flows into India and joins the Ganges.
More than 60 per cent of the total drainage basin of the Trishuli lies in Tibet with about 9 per cent being covered by snow and glaciers. 85 per cent of its catchment area of 4,640 square kilometres (1,790 sq mi) lies above 3,000 metres (9,800 ft) out of which 11 per cent lies above 6,000 metres (20,000 ft). It has been regularly gauged at Betrawati at an elevation of 600 metres (2,000 ft). The average lowest and the melt season discharges of this river are close to average discharges recorded on the Narayani River.
Trisuli is Nepal’s most popular rafting river with impressive gorges, exciting rapids, some easier sections and easy accessibility from Kathmandu and Pokhara. Rafting in Trisuli is one of the most popular outdoor activities in Nepal. Trishuli River is made up of snow melt of Mt. Ganesh and Langtang Himal.  Easy access to the Prithivi Highway makes “breaking off” the journey easy. Chitwan National Park is also easily accessible.
