Guilin in the Guangxi Zhuang Autonomous Region is one of China's top tourist attractions because of its spectacular tower karst. There are numerous steep karst towers with huge caves inside. Collapsed caves form dolines and natural bridges like the Elephant Trunk Hill. The whole area is crossed by the Lijiang river.
The city of Guilin is located in the center of the area. Three important and very popular show caves are located close to the city, Reed Flute Cave, Seven Star Cave and Pierced Hill Cave. Several other caves are located to the south, Crown Cave, Lotus Flower Cave, Silver Cave, and Rich Fish Cave. The eighth cave of the area is Black Cave to the northeast at Guayang.
