Where the Yangtze, Mekong, and Salween flow side by side through the Hengduan Mountains.
Three Parallel Rivers of Yunnan Protected Areas
The Three Parallel Rivers of Yunnan Protected Areas is a UNESCO World Heritage Site in the mountainous northwest of Yunnan Province, China. The park protects a striking section of the Hengduan Mountains where three of Asia's great rivers, the Yangtze (Jinsha), the Mekong (Lancang), and the Salween (Nu), descend from the Tibetan Plateau and run for more than 170 kilometers in parallel deep gorges without ever merging. This unusual confluence of geography makes the area one of the most dramatic river landscapes in the world.
Beyond its sheer scenic power, the protected area is exceptional for its ecological richness. The combination of north-south mountain corridors and the absence of full Pleistocene glaciation allowed the region to act as a refuge and dispersal route for plants and animals across the Eurasian continent. As a result, an unusually high concentration of China's biodiversity is concentrated in a land area of less than half a percent of the national territory, supporting rare species from black-necked cranes and snow leopards to the endemic Yunnan snub-nosed monkey.
The site is also one of China's most culturally diverse regions. Within its bounds live more than twenty ethnic minority groups, including Naxi, Lisu, Tibetan, Bai, Yi, Pumi, Nu, and Derung communities, each preserving distinct languages, religious traditions, and ways of life that are closely tied to the surrounding river valleys and alpine pastures. Altogether, the landscape, biodiversity, and human cultures combine into a World Heritage Site whose significance extends well beyond its regional setting.
