Lugu Three Islands
The Three Islands of Lake Lugu are Nixi Island, Liwubi Island and Naizhongpu Island, whose exquisite scenery is breathtaking. Nixi is the smallest of the three, covered in moss and shrubs. Liwubi is the largest island on Lake Lugu; at the end of the flower-lined path stands Liwubi Temple, a Tibetan Buddhist monastery that draws many worshippers. The island also has a white pagoda, the spirit tower of A Yunshan, steward of the Yongning Mosuo chieftain's residence. A Yunshan was a renowned figure in Yunnan, Sichuan and Tibet. Naizhongpu Island is lush with trees and home to countless birds. On the islands you can ride a horse or walk around to enjoy the beauty of Lake Lugu, and visit the Mosuo villages, whose people are known for their simple, genuine ways.
Walking Marriage Bridge
The most famous spot in Caohai is the Walking Marriage Bridge, dubbed the “Number One Magpie Bridge Under Heaven”. It is a 300-metre wooden bridge extending out through the reeds of Caohai, and it is where Mosuo men and women carry out the walking marriage custom. Today the old bridge's timber has rotted and lies scattered across the marsh. The new bridge runs right beside the old one, spanning Caohai and providing convenience for local residents.
