Set in the northern Himalayan range in the Gorkha land of Nepal, Manaslu is a serrated "wall of snow and ice hanging in the sky". The three sides of the mountain fall in steps to terraces down below, which are sparsely inhabited with agricultural operations practiced on the land. Apart from climbing Manaslu, trekking is popular in this mountain region, as part of the Manaslu Circuit, a notable path by trekkers in Nepal.
The Manaslu Conservation Area, declared as such in December 1998 under the National Parks and Wild Life Conservation Act, subsumes Manaslu within it. The area covered under the conservation zone is 1,663 square kilometres (642 sq mi) and is managed by the National Trust for Nature Conservation (NTNC) of Nepal. The status of "conservation area" applied to the Manaslu area or region was with the basic objective "To conserve and sustainable management of the natural resources and rich cultural heritage and to promote ecotourism to improve livelihood of the local people in the MCA region."
Manaslu Himal, as it is popularly known among trekkers, provides views of the snow-covered mountains of the Himalayas and allows close interaction with the different ethnic groups who live in hill villages scattered along the trek route.
The trekking route is through mountains prone to the consequences of monsoon rainfall, land slides and land falls. Encounters with passing yaks, and hypothermia and altitude sickness, are common. Trekking to Manaslu is thus a test of endurance.
