Mt. Amnye Machen has long been considered a sacred mountain and a place of pilgrimage. In the past, up to 10,000 Tibetans would make the 120-mile circumambulation of the mountain each year. The first European explorers described it as one of the great geographical discoveries of the twentieth century. Itinerary for the Mt. Amnye Machen trek is here: Holy Mt. Amnye Machen trek
