The Tianmen Mountain in Zhangjiajie, China is famous, not only for The Avenue Toward Heaven – one of the world scariest roads, but also for the glass Skywalk. This attraction is doubtless for the brave hearted as not everyone is ready to enjoy the scenery and observe the absence of solid ground under their feet even further than his eye could see. The walkway is built at a height of 4700 feet (1,430m) above sea level with a dimension of 200 feet (60 metres) long. The 2.5 inches thick transparent path will definitely make your visit the Tianmen Mountain Park, the second national forest park in Zhangjiajie region, unforgettable. The only condition put for the courageous tourists of Tianmen Mountain Skywalk is to put the cloth slippons over their shoes in order not to get dirty or scratch the miraculous walkway.
