Jianshui Swallow Cave

The Jianshui Swallow Cave has a long underground river, and to ensure the water level of the underground river, there is a dam at the very end. Above the dam is a very, very open space, large enough for a concert. In this vast cave hall, there are various forms of stalactites, as well as sedimentary pools similar to those in Jiuzhaigou, looking like little bathtubs. On the way back, you will pass the dam's outflow, which emits a deafening sound of flowing water.
