Zhangjiajie Global Geopark is located in the mountainous area of the western region of Hunan Province, China, with a subtropical humid mansoon climate. The outstanding landscape is dominated with more than 3000 peaks and pillars of quartz sandstone, which are rare in the world for their large number, height and fairly pure composition. In the long Chinese history, it has been honored as "the most fantastic mountain under heaven" and "a living Chinese landscape painting." [Photo by Zhao Zhendong/ China.org.cn]
