If you've seen the movie Avatar, you've already seen Zhangjiajie National Forest Park - but don't let that stop you seeing them in real life. These mountains were the inspiration behind the Hallelujah Mountains in the mythical world of Pandora in the movie Avatar, and it's easy to see that when you visit. In fact, the government has even changed the name of one of the mountains in the park to "Avatar Mountain". The park, however, does offer so much more than just that one set of mountains.
