The Binghudong underground waterfall is situated in the hilly limestone areas north of Jinhua County, Zhejiang. There are also many limestone caves in the area. One of them, the Binghudong cave, is narrow at the entrance and wide inside. The waterfall there has a drop of 30 meters and is surrounded by stalagmites. The water roars down from the brindk on top of the cave and merges with a subterranean stream. Such waterfalls are to be found also in the karst regions in Guangxi, Yunnan and Guizhou.
