Zhangjiajie Forest Park, China

Zhangjiajie National Forest Park is a unique national forest park located in Zhangjiajie City in northern Hunan Province in the People's Republic of China. The most notable geographic features of the park are the pillar-like formations, some of which are over 800 metres (2,600 ft) in height. They are the result of many years of erosion. According to park officials, photographs from Zhangjiajie inspired the floating Hallelujah Mountains seen in the the movie Avatar.
