This region is blessed 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 touristic area but we can see significant views of Mt.Everest, Makalu, and hundreds of other mountains just on your eye. Sherpa, Rai and Limbus are the main inhabitants of this region.

Walking north up the Arun river to Sedua and Num, then crossing Barun La(4110m.)into the upper Barun khola valley for a close look at Makalu. You can put together an even wilder trek by crossing Sherpani col and west col into the upper Hongu valley. The highest point of this trek is Salpa Bhanjyang and also we can visit Hindu holy call Lake Salpa holy Lake(3414m.).
