Baxiandong Heavenly Lake
Drive all the way to Baxiandong Heavenly Lake after you leave Shanwan Stone Forest. The heavenly lake is located in the center of the depression. There are eight caves, such as Pipa Cave and Niubi Cave, on the surrounding hillsides. Stone forests are clustered on the karst hills, which are in peculiar shapes. There are many karst caves around Baxiandong Heavenly Lake. In the 1960s and 1970s, Luota people "blocked the underground river at the sinkhole", connected the groundwater at nearby caves, blocked the downstream groundwater and converged them into a reservoir, which helped form the beautiful scenery. This is a fabulous project of the reservoir construction by plugging the hole in karst depressions in China.
