This is one of the remotest trekking region in Nepal.The Makalu-Barun area is little known to most tourists due to its relative inaccessibility.
The valleys, particularly the Barun valley, treasure some of the last remaining pristine forests and alpine meadows of Nepal in its untouched form. From the bottom of the Arun valley, at just 435 m above sea level, the Himalaya rise to the snow-capped tip of Makalu- 8.463 m the fifth highest mountain--within a 40 km distance.Within this wide range of altitudes and climates, the Makalu-Barun area contains some of the richest and most diverse species of plants and animals in Nepal, With more than 3.000 species of flowering plants, hundreds of orchid varieties, 48. primroses, and 25 species of rhododendrons, abundant wildlife, including the endangered red panda and musk deer, the ghoral, Himalayan tahr, leopard and 400 bird species, at least 16 of which are extremely rare, makes this area a “Naturalist’s Paradise” The Makalu-Barun National Park and Conservation Area was established in 1992 as Nepal's eighth national park and the first to include an adjacent inhabited conservation area as a buffer.
