The elevation of Tianmen Mountains is 1518.6 meters (the highest one in Zhangjiajie); people may feel amazing that about 40 peaks inside the mountain area are over 1000 meters. Due to the high elevation of the mountain, the day time is longer than the night hours and the temperature on the mountains is about 10 degree centigrade lower than the Zhangjiajie city, the sunrise on the mountain is 30 minutes earlier and the sunset is 45 minutes later than it is in the city areas. Thus it is known as an endless sky without darkness.

The mountain is famous for its unique natural miracle - the Tianmen Cave; it was authorized as a national forest park in July, 1992. The door-alike cave was created after the cliff collapsing in ancient time. Tianmen Mountains is rich in Chinese culture; it is regarded as the Top 1 Heaven Mountain in the west part of Hunan province and the sprit of Wuling (an old name of the county here). This place has absorbed the essence from the nature for thousands years, therefore visiting the holy temple on the mountain – Tianmenshan Temple has become a popular way to pray for a safe and healthy life.
