This trek was restricted to mass tourism to preserve its heritage in the Upper Dolpo Region. After it was opened in 1989, adventurists come here to experience the true wilderness of the Himalayas. This trek gives you a chance to see abandoned Buddhist monasteries and a diverse mountain wildlife like the Blue sheep, Mountain Goat, Jackal, Wolf and the legendary Snow Leopard. A walk through the Shey Monastery is a peak into the heritage of this land. The best time to trek here is from September to November.
