Makalu Base Camp is blessed with an incredible diversity of natural beauty and culture. Due to its isolation and lack of tea houses this area still receives few trekers. Sherpa, Rai and Limbus are main habitants in this area. 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 (8463m). You can put together even wilder trek by crossing Sherpani Col and west Col into the upper Hongu valley. The second part of the trek is very difficult and almost impossible without previous experience.
