Jiuzhaigou Valley is one of China's most spectacular natural landscapes — a UNESCO World Heritage Site in northern Sichuan Province where turquoise lakes, multi-tiered waterfalls, and snow-dusted peaks are set in dense forests of spruce, fir, and birch. The name means "Nine Village Valley," after the Tibetan settlements scattered along the valley floor.
The park covers a Y-shaped system of three valleys, each with its own character. Mirror Lake, Five Flower Lake, and Pearl Shoal Waterfall are among the highlights. The water's extraordinary colours — vivid blue-greens caused by calcium carbonate deposits and algae — are real, though they still look improbable in photographs. Autumn, when the surrounding forests turn gold and red, is the most popular season.
