Tianmen cave: a Glass Sky Walk

quoted via Jared Miles [One of the main attractions of Tianmen Mountain is Tianmen cave, which is technically not a cave. Rather, it is a water-eroded hole in the cliff face, with the highest elevation of it's kind in the world. It can be seen in the image above. Tianmen Mountain is able to lay claim to the longest cableway in the world, spanning a distance of 7455 metres along, over a rise of 1300 kilometres. If the altitude wasn't enough to dissuade you, the adrenaline-junkies that likely run the development of the park have created The Walk of Faith, a journey consisting of several kilometres of glass walkways squared against the cliff face.
