Arun River

The Arun River is a trans-boundary river and is part of the Kosi or Sapt Koshi river system in Nepal. It originates in Tibet Autonomous Region of People's Republic of China where it is called Bum-chu.
The Arun is the largest trans-Himalayan river passing through Nepal and also has the greatest snow and ice covered area of any Nepalese river basin. The Arun drains more than half of the area contributing to the Sapta Kosi river system but provides only about a quarter of the total discharge. This apparent contradiction is caused by the location of more than 80 percent of the Arun's drainage area in the rain shadow of the Himalayas.
Fact File:

Rafting on Arun is undoubtedly the most exciting white water river rafting in Nepal. The river takes shape from the melting snow of Mt. Makalu (8463m), the world’s fifth highest peak, and flows amid the thick woods of the famous Arun valley before winding its way down through the hinterlands of eastern Nepal.
The rafting starts at Kartike Ghat, where you can reach by a five-day trek after a short drive. The trekking route follows a 3000-meter high ridge through beautiful woods and meadows with magnificent views of Kanchenjunga, Makalu and the Everest mastiff along the way. Alternatively, you can fly to Tumlingtar and trek to Kartike Ghat, which will reduce your trekking days considerably.
