Wulingyuan ([ù.lǐŋ.ɥɛ̌n]; Chinese: 武陵源) is a scenic and historical site in the Wulingyuan District of south-central China’s Hunan Province. It was inscribed as a UNESCO World Heritage Site in 1992. It is noted for more than 3,000 quartzite sandstone pillars and peaks across most of the site, many over 200 metres (660 ft) in height, along with many ravines and gorges with attractive streams, pools, lakes, rivers and waterfalls. It features 40 caves, many with large calcite deposits, and a natural bridge named Tianqiashengkong (Bridge Across the Sky), which is one of the highest natural bridges in the world.
The site is situated between 29°16′0″N 110°22′0″E and 29°24′0″N 110°41′0″E in Zhangjiajie City and lies about 270 kilometres (170 mi) to the northwest of Changsha, the capital of Hunan Province.
