张家界(Zhānɡ Jiā Jiè) in Hunan Province China is famous for the UNESCO World Heritage Site - 武陵源(Wǔ Línɡ Yuán).
It covers an area of 690 square kilometers (266 square miles). Wulingyuan forms part of the Wuling Mountain Range. The scenic area consists of four national parks, which are the Zhangjiajie National Forest Park, Suoxi Valley Nature Reserve, Tianzi Mountain Nature Reserve and the recently added Yangjiajie Scenic Area. Overall there are over 560 attraction sights to view.
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.
