Often hailed as the “Gateway to Heaven,” Tianmen Mountain stands as one of China’s most breathtaking natural marvels. Perched above the city of Zhangjiajie in Hunan Province, this majestic peak rises to 4,980 feet above sea level. From its lofty heights, visitors are rewarded with sweeping panoramic views of rolling valleys, jagged cliffs and pristine forests that have remained untouched for centuries.
