This is a marvelous and easy trek for trekkers who do not want to encounter a mass influx of tourists on the trail but equally enjoy beautiful scenarios of valleys, splendid views of silvery mountains. Most of the people love and enjoy the Trek. This region is blesses with an incredible diversity of natural beauty and culture. Arun valley trek is between two highest mountains, Everest and Makalu. It is really a non tourist area but we can see significant views of mt. Everest, Makalu and hundreds of other mountain just on your eye. Sherpa, Rai, and Limbus are the main inhabitants of this region. The tempting views of Arun River and valleys you can be see on the way of trekking terrain. We do fully camping trek because there is not available of the Teahouse and Lodges. Trek starts from Tumlingtar and follows Arun-river towards north to Num and travel northeast to the source of Arun River, which is located beyond the old trading post of Kimathanka. Visit the isolated villages of Hatia, Chepuwa, Ritak and Thudam near the Tibetan border of northeast Nepal. From Thudam you travel south to Topkegola. Another village shares the history of upper Tamur.
From Topkegola instead of taking lower trail through Mewa Khola (river) to Donje, Phapung and Lingtep the proposed trail climbs up to the ridge of Jaljala Himal (4800m) and continues the snow traverse through the high mountain trail to Milke Danda and descend to Chainpur. The traverse involve about 4 days of travel through snow and average (4700m) elevation. Depending upon them weather and physical condition of the trekkers the higher trail would be taken. From Milke danda it is also possible to descend to Basantapur and catch bus to Biratnagar. Then move to chainpur and back Tumlingtar.
