Lugu Lake is one of the most beautiful highland lakes in China, famous for its crystal-clear water, surrounding snow-capped mountains, unique island scenery, and the traditional culture of the Mosuo people.
Located on the border between Ninglang County in Yunnan Province and Yanyuan County in Sichuan Province, Lugu Lake is a natural wonder shared by two provinces. The eastern side of the lake belongs to Lugu Lake Town of Yanyuan County, Sichuan, while the western side is part of Yongning Township, Ninglang County, Yunnan.
With its peaceful environment, fascinating ethnic traditions, and breathtaking landscapes, Lugu Lake has become one of the most popular destinations in Southwest China.
Geography and Natural Features of Lugu Lake
Lugu Lake stretches from northwest to southeast, covering an area of approximately 50.1 square kilometers, with a water storage capacity of about 2.252 billion cubic meters.
The lake was formed by geological movements and is a typical plateau fault lake. It belongs to the water system of the Yalong River, a tributary of the upper Yangtze River. The lake is also the upper source of the Xiaojin River, which eventually flows into the Jinsha River through the Yalong River.
Located in the beautiful Yongning Basin, Lugu Lake is the third-largest deep-water lake in China. Surrounded by mountains and forests, the lake has a horseshoe shape and features a unique combination of plateau scenery and cultural landscapes.
Mosuo Culture Around Lugu Lake
Lugu Lake is mainly inhabited by the Mosuo, Yi, and Pumi ethnic groups, with approximately 13,000 local residents living around the lake.
The Mosuo people are especially famous for preserving their traditional culture, including:
* Unique family structures
* Traditional festivals
* Ancient religious beliefs
* Traditional songs and dances
* The famous “walking marriage” custom
The combination of spectacular natural scenery and distinctive ethnic culture makes Lugu Lake one of the most fascinating cultural tourism destinations in China.

The mountain provides spectacular views overlooking the entire Lugu Lake area and is one of the most iconic landmarks of the region.
Houlong Mountain Island
Houlong Mountain is a long peninsula extending about 4 kilometers into Lugu Lake.
In Mosuo legends, Houlong Mountain represents the male mountain god, while Goddess Mountain represents the female goddess. According to local mythology, the two became mountains and continue their eternal love story across the lake.
The area is also closely connected with the famous Mosuo “walking marriage” tradition, an important cultural symbol of Lugu Lake.
Visitors can enjoy beautiful lake views, forests, and peaceful walking trails here.
