Arun River in Tibet

The Tibetan name Bum-chu may refer to a religious ceremony attempting to divine prospects for the coming year from the level of water in a pot or well,[3][4] chu is the Tibetan word for water. The river also originates near Gutso in Nyalam County of Tibet. Around 17 kilometres (11 mi) downstream the Men-chu joins it. The Tingri county occupies the upper reaches of the Bum-chu and the lateral valleys formed by its tributaries, the foremost of which are Lolo-chu, Shel-chu, Rongpu-chu, Trakar-chu, Kharda-chu, Ra-chu Tsangpo, and Langkor Gya-chu. The Yeru Tsanpo converges with Bum-chu in Tingkye County, which accommodates the lower Bum-chu valley. Another river that meets Bum-chu is Trakar-chu. The river flows past the town of Kharda, gateway to the Khangzhung east face of Everest. The force of its accumulated waters carves its way, south of Drengtrang, through the main chain of the Himalayas directly between the mountain massifs of Makalu and Kangchenjunga into Nepal.[2][1] Since the river's elevation is about 3,500 metres (11,500 ft) at the border while Makalu and Kangchenjunga are both about 8,500 metres (27,900 ft), the valley is some 5,000 metres (16,000 ft) deep, one of the world's deepest.

Trip Information

The Arun River White Water Rafting has four main river systems with more than two hundred fifty sizeable tributaries, and it is one of the most mighty and powerful rivers of Nepal. The major rivers are Sapta Kosi in extreme eastern Nepal, the Narayani in central Nepal, the Karnali in western Nepal, and the Mahakali in far western Nepal. The Arun River is one of the tributaries of Sapta Kosi that flows into Eastern Nepal. In addition to enjoying your rafting trip, you have a chance to experience more than one hundred different dialects belonging to various ethnic groups on your trip. Meeting different ethnic groups of people during the rafting is all a part of an unforgettable experience.

The journey to the put-in point for rafting on the Arun River engages a 16-hour road trip, with transportation by bus to Hile, followed by a 3-day trek to the village of Bumbling. Or 45 minutes scenic flight to Tumlingtar, which is the obvious and most convenient starting point from Kathmandu, and only forty minute walk to the river.  This 70km of river action takes 5 – 6 days. The return journey from Chatara, the take-out point of Arun Rafting/Kayaking, is 16 hours to Kathmandu. It is also possible to arrange a flight from Biratnagar (a 1-hour road journey from Chatara), and the flight takes around 50 minutes to Kathmandu, and it’s an additional cost. This stunning Arun River is only available for those undertaking an expedition. The scenery on both the trek and river is matchless and untouched.

The upper part of Arun is one of the most powerful and respected rivers exclusively with the unique Bublick and double catamaran in Nepal River. It flows cutting through the Himalayas with deep and awesome gorges, lush valleys, and superb riverside beaches. The powerful current and large water volume ensure enormous and striking rapids are bumped into the length of this river journey. These rapids can be challenging and technically complex for the whitewater Rafter. The Arun is an outstanding choice for a long trip for those who are seeking real exciting activity, and the adventure of encountering huge rapids in an idyllic setting. This is the first choice for those who want an expedition into the wilderness in Nepal. We “Friendship World Trek” are glad to organize this Rafting / Kayaking trip considering our client’s safety and enjoyment. The itinerary can be customized according to your wish and holiday schedule.
