One of the province's most pristine lakes, Lugu and it's surrounding area are also the spiritual homeland of the Mosuo people. The lake straddles the border of Yunnan and Sichuan and is very deep, with its deepest point sitting 40 meters below the surface. It is flanked by the impressive escarpment Lion Mountain, the holiest place in Mosuo folklore. Boat rides are a common pastime for visitors, and are rowed by locals as no motorized traffic is allowed.
