Today, with its towering karst spires, rich brown earth and lush forests, Zhangjiajie has become a striking and iconic Chinese landscape. Made a UNESCO Heritage Site in 1992, and immortalized by the film Avatar, the park is a dramatic landscape of deep, forested canyons and enormous, isolated limestone peaks, each with their own miniature ecosystems akin to bonsai forests. This tour also takes in Zhangjiajie Grand Canyon Glass Bridge, the world's longest and highest glass-bottomed bridge. Walk it if you dare!
