Wulingyuan is a scenic and historical site in the Wulingyuan District of South Central China's Hunan Province. 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 picturesque streams, pools, lakes, rivers, and waterfalls. It features 40 caves, many with large calcite deposits and a natural bridge named Tianqiashengkong, which is one of the highest natural bridges in the world. The site also provides habitat for many vulnerable species, including the dhole, Asiatic black bear, and Chinese water deer.
