Welcome to Zhangjiajie National Park. Filled with huge rocks, to which the trees cling on, it looks as if they have been taken from old manuscripts of ancient Chinese art. The abundance of rivers and low level cloud streams often cause the rock peaks to become shrouded in a heavy mist. Not surprisingly, the film Avatar features these mountains, as the views from them are as if from another world – mesmerising – and are quite unlike any other place.
