About Tianmen Mountain

Tianmen Mountain stands just outside Zhangjiajie in Hunan, climbed by a cable car that runs from the city to the summit. On top, cliff-hugging walkways and glass paths circle the peak, and a long staircase descends to the natural arch known as Heaven's Gate. The national forest, with its sandstone pillars, is a separate day trip. April to May and September to October are mild; summer is hot and crowded, winter cold and misty.
