Summery

A powerful and famous river. Little travelled, it offers a shorter and easier alternative to the Sun koshi, with big rapids of moderate difficulty but the necessity of flying in to Tumlingtar makes it relatively expensive for such a short trip.

The River

The Arun is respect as on of the most mighty and powerful rivers of Nepal .The lower valley is in parts quite well populated with a wide variety of different tribes. The whole area is relatively unspoilt , and sees only a few trekking groups, mainly taking the Eastern approach to Everest.

Rafting

Only a few company schedule rafting trips on the lower half of the Arun and it only sees a few trips each year. However, the rafters who have done it and talks to us, recommend it as the ideal trip for someone who wants to run a big white water river but hasn’t got the time to raft the Sun koshi or the Karnali. They say that the river is , in all ways, better than the trusuli and should perhaps best be compared with bottom half of the Sun koshi-excellent big rapids, fine beaches for camping , a beautiful unspoilt valley, picturesque villages and a wooded gorge- the ‘jungle corridor’ with its associated wildlife.

Tumlingtar is the obvious and most convenient starting point and everyone recommends that you fly into here as it is only a short direct flight from Kathmandu and only forty minutes walk from the river. The 70 km down to chatra has been kayaked in a day, but normally makes a relaxed 3 day raft trip and you can then fly back to Kathmandu from Biratnagar if you wish.
