It is certainly not a path for the faint-hearted. On one side a sheer rock face, on the other a 4,000 ft drop - and all to separate the brave traveler from a deadly plunge is a 3ft-wide, 2.5in thick walkway. And if that is not enough to bring terror into the pit of your stomach, the path running alongside a Chinese mountainside is made out of glass, allowing a crystal-clear view of where one false step can take you. <br />So it was perhaps understandable that this woman tackled the walkway by sticking as close to the cliff as possible, feeling her way along with tentative steps. <br /> <br />The skywalk is situated 4,700 ft above sea level on the side of the Tianmen Mountain in Zhangjiajie, China. <br />The 200ft long bridge joins the west cliff at the Yunmeng Fairy Summit, the summit of Tianmen Mountain and Zhang Jiajie. <br />And it would appear to be too scary for the cleaners - tourists are asked to put on shoe covers before passing to help keep the path clean. The pathway, built earlier in the summer echoes the glass-bottomed walkway at the Grand Canyon in the U.S. <br />The 70ft bridge is 4,000ft above the natural wonder and allows tourists to look through 2.5in of crystal-clear glass to the Canyon floor below. <br />The Tianmen mountain, literally translated as Heavenly Gate Mountain is so called because of a huge natural cave that occurs halfway up to the summit. <br /> <br />Situated in the Hunan Province, Its highest peak is around 5,000ft above sea level and it is home to a wealth of rare species of plants <br />A four-mile-long cable car was constructed in the park, which is said to be the longest of the same type in the world. <br />And no matter how terrifying the glass walkway may be - it can only be an improvement from another sky high mountain walkway located in the same province. <br />The Shifou Mountain, located 82 miles away, offers sightseers a 3ft-wide road made of wooden planks thousands of feet high. <br />When finished the wooden 'road' - which is the width of a dinner table - will stretch for 1.8miles making it China's longest sightseeing path. <br /> <br /> <br /> <br /> <br />longest passenger cableway of high mountains in the world, China's newest tourist attraction, Don't look down! The terrifying see-through path stuck to a Chinese cliff-face 4,000ft above a rocky ravine
