Tianmen Skywalk, China
The Tianmen Skywalk, a hazardous glass bridge in China, clings to a cliff in Zhangjiajie National Forest Park. Spanning 330 feet, it lures tourists seeking thrills.
Thousands visit annually, facing their fear of heights. Looking down through the transparent floor reveals staggering elevation, an unnerving experience. China certainly favors constructing bridges in lofty locations.
