Zhangjiajie, a city in the northwest of China`s Hunan province, is home to the famed Wulingyuan Scenic Area. This protected zone encompasses thousands of jagged quartzite sandstone columns, many of which rise over 656 ft., as well as caves filled with stalactites and stalagmites. Wulingyuan also encompasses forests, rivers, waterfalls and 2 large natural land bridges, as well as endangered plant and animal species. As a matter of fact, it is famous for its sandstone landforms, precarious peaks, limpid streams, dense lush forests, and large karst caves. More than 3,000 mountain peaks of various shapes are congregated here in the park, forming a spectacular scenery.
