The picturesque Tianmen Shan (Heaven's Gate Mountain) is a huge rocky gap carved by eons of weather and seasons. It measures 180 feet wide and 430 feet high, and is five miles south of  Zhangjiajie in northern Hunan Province, and 800 miles west of the port city of Shanghai .

Before the experience of tramping up the enormous stairway, visitors can board a five-mile aerial tram after their scenic bus ride from the city. For more information, go to english.zhangjiajie.gov.cn
