"First Natural Bridge Under Heaven", or "Bridge Across the Sky" as it is formally known, is located in Zhangjiajie National Forest Park, China. This natural beauty is a large sandstone block that has had a large, vertically elliptical section hollowed out of it near the summit, leaving a "bridge" at the top connecting the two pieces. One of the sides is a masive block while the other side is a nearly complete freestanding obelisk, except that it is still connected to the massive block at the base and at the top.

It spans over 25 meters with a vertical height of 357 meters, being a natural stone bridge (2 meters wide and is about 5 meters thick) with the maximum vertical heights in the world. In fact, the two mountains linked by the bridge were originally one mountain. The marvelous bridge was carved by the force of mighty wind and water.
