Zhangjiajie is located in the west of Hunnan Province, China. Zhangjiajie was thrust into foreigner travelers' eyes after the movie Avatar. The Hallelujah Mountains in Avatar were inspired by Heavenly Pillar in Zhangjiajie National Forest Park. Zhangjiajie is famous for its precarious peaks, limpid streams, dense forests, and large karst caves. In 1982, Zhangjiajie National Forest Park became China's first national forest park.
