Si Ding Cuo Sacred Lake: The Mirror of the Sky in Western Sichuan
Why Visit Si Ding Cuo?
Hidden deep along the Western Sichuan loop, Si Ding Cuo Sacred Lake is one of the region’s most untouched alpine landscapes. Sitting at an altitude of 4,200 meters, it blends snow-covered peaks, crystal-clear water, and vast starry skies into a single, quiet scene. Unlike well-known destinations such as Daocheng Yading, Si Ding Cuo remains largely undeveloped, offering travelers a rare sense of solitude and spiritual calm.
Often called the “Mirror of the Sky,” Si Ding Cuo reflects Mount Gongga and the surrounding peaks so clearly that the line between sky and land seems to disappear.
Where Is Si Ding Cuo Sacred Lake?
Si Ding Cuo is located near Jiagenba Town, Kangding City, in Garzê Tibetan Autonomous Prefecture. Backed by Mount Gongga (7,556 m)—known as the “King of Shu Mountains”—the lake faces the rolling peaks of the eastern Tibetan Plateau.
The area is quiet and free of commercial development, with only wind, water, and distant prayer flags breaking the silence.
What Makes Si Ding Cuo Special?
Snow Mountains Reflected Like a Mirror
On clear days, Mount Gongga and nearby peaks are perfectly reflected in the still water. Waiting for sunrise here is unforgettable: as the first light touches the snow, the lake slowly turns gold, as if the entire plateau is waking up.
A Sacred Lake on the Plateau
In Tibetan, “Si Ding Cuo” means “Pearl Sea.” Local Tibetans regard it as a holy lake and often walk clockwise around the shore to pray for blessings. The water’s blue-green color comes from its mineral-rich composition, appearing sapphire-like in winter and emerald-toned in summer.
One of Western Sichuan’s Best Stargazing Spots
Thanks to its high altitude and minimal light pollution, Si Ding Cuo is an exceptional place to photograph the Milky Way. On clear summer nights, stars stretch across the sky in stunning detail, reflected faintly on the lake’s surface.
