Dolpo is the most remote and least developed district in Nepal. Although a few anthropologists and geographers had explored the region, the entire district was closed to trekkers until 1989 when the southern part of Dolpo  was opened to organized trekking groups. Peter Matthieseu’s “The Snow Leopard” and Snellgrove’s “Himalayan Pilgrimage” have contributed to the mystique and attraction of Dolpo.
