Tianmen Mountain:the Southern Part of Zhangjiajie City

TianmenMountain, which located 3 kilometers away from the southern part of Zhangjiajie city, with an altitude of 1518.6 meters. it is a platform-shaped mountain surrounded by bluffs. what is more unwonted is the giant hollow formed in the one-thousand-meter-long bluff-- Tianmen Cave. it is a rare and marvelous geological spectacle, which was labeled as a national park in 1992. in 1999 some pilots from nine countries participating in the world tournament of aerobatics flew through Tianmen Cave successfully for the first time, which was rather sensational.
