China's most spectacular national park — a fairy-tale landscape of turquoise lakes, cascading waterfalls, and snow-capped peaks deep in the Tibetan highlands of northern Sichuan.
UNESCO World Heritage Site and Biosphere Reserve — China's fairy-tale valley of coloured lakes and waterfalls.
Jiuzhaigou (九寨沟, "Nine Village Valley") is one of China's most breathtaking natural wonders — a high-altitude national park in the Aba Tibetan and Qiang Autonomous Prefecture of northern Sichuan Province. Designated a UNESCO World Heritage Site in 1992 and a UNESCO Man and Biosphere Reserve in 1997, it is renowned worldwide for its extraordinary concentration of coloured lakes, multi-tiered waterfalls, and sweeping alpine forests.
The valley takes its name from the nine Tibetan villages historically nestled within it, whose inhabitants have shaped the cultural landscape of the region for centuries. Today, the park covers roughly 720 km² and encompasses three main valley branches — the Shuzheng Valley, the Rize Valley, and the Zechawa Valley — each offering distinct scenery and iconic landmarks.
What makes Jiuzhaigou truly unique is the extraordinary chemistry of its waters. Rich in calcium carbonate and travertine, the lakes shimmer in impossible hues — electric turquoise, emerald green, deep sapphire, milky white — that shift with the angle of sunlight and the season. Submerged ancient tree trunks, visible through crystal-clear depths, add to the otherworldly atmosphere.
The park closed for extensive restoration following a major earthquake in August 2017, reopening in phases from 2019 onwards. Today it welcomes visitors on a strictly managed ticketed entry system with daily visitor caps to protect its fragile ecosystem.
Average temperatures at valley floor (~2,200m). Peaks and upper valleys are significantly colder. Dress in layers year-round.
