The trekking route crosses both well-known areas as well as other lesser-known sites that are very poor but have enormous tourism potential. The purpose of developing the trail was to promote socioeconomic benefits to mountain communities. The Great Himalaya Trail covers 16 districts, ranging from Dolpa that connects with the Tibetan plateau, to Darchula, which borders India. Trekking in Nepal is a major attraction for tourists, but popular destinations have been limited to the regions of Solukhumbu, Everest, Annapurna and Langtang.
