Tianmen Mountain National Forest Park lies 8 kilometers south of the city of Zhangjiajie in China. The mountain is best reached by cable car. Tourists can walk on kilometers of paths built onto the cliff face at the top of the mountain, including sections with glass floors. The path leading to Heaven’s Gate is 1.600 meters (5,250ft) long . An 11 km road with 99 bends also reaches the top of the mountain and takes visitors to Tianmen cave, a natural hole in the mountain of a height of 131.5 m
