This aerial view of Chongqing Karst Topography National Park, the first of its kind in China, shows a stunning combination of color, where two tree species divided by a path form two worlds of pink and green.

China’s karst landscapes cover Chongqing, Guangxi Zhuang Autonomous Region and the provinces of Guizhou and Yunnan, and were inscribed on the UNESCO World Heritage List in 2007.

Karst landscapes are formed when soluble rocks gradually dissolve over thousands of years, and typically feature vast underground caves.
