Shi Er Bei Hou · Shuanghegu Scenic Spot is composed of underground river valleys, pits and gypsum caves and features rich underground karst landform. Cliffs in the underground river valleys come in different shapes and look like valuable artworks. There are also rare cave animals and plants such as blind fish and wild giant salamanders in the caves. The waterfall plunges from the top of the pit, which is very magnificent. The flowing streams in the bottom of the pit coupled with the growing huge original banana forest and bamboo forests offer picturesque scenery. The huge "underground terraces" in gypsum caves are amazing.
