The Upper Barun Valley is among the richest for birds in Nepal. It is virtually untouched by man. Birdwatchers have rarely visited the region because it is not easily accessible. There are no trekkers lodges within Makalu-Barun National Park. There is one small tea house at Langmale (near the Base Camp) run by a third-generation native of the upper Barun Valley. In an effort to control and consolidate the impacts of camping, the pitching of tents is only allowed in designated campsites.
