In the Yunnan province of China across 400 square kilometers lies the most impressive karst display in the world. 270 million years ago the land was covered by a sea, which eventually receded and disappeared. Limestone dominated the landscape and the elements sculpted it into what we have today - a forest of stone peaks in various forms and sizes, which can create an unbelievable labyrinthine terrain for visitors to enjoy. It is one of China's most famous natural attractions, which also has its underground parts. The possibilities are simply endless.
