World-famous Huangguoshu Waterfall, known as "the first waterfall in China", is located on the Baishui River, one of the headstreams of the Dabang River in the Zhenning Bouyei-Miao Autonomous County southwest of Guizhou. The fall is the largest of this kind in China and one of the most magnificent waterfalls in the world, measuring 81 meters wide, with a drop of 74 meters. It has been found that the falls in this area consist of 18 falls on the ground and 4 underground falls. Among them, the Huangguoshu Waterfall is the largest with a flow of more than 700 cubic meters of water per second and huge amounts of water seem to be pouring from the sky. Like the Milky Way descending from the heaven, the Huangguoshu Waterfall rushes into the Xiniu pond, sending foams up by 100 meters, and roars can be heard kilometers away. With typical karst topography, the area around the Huangguoshu Waterfall boasts a cluster of fascinatin water-eroded caves. The "Fairy Dragon Cave," located four kilometers upstream from the waterfall, is one of the most interesting among all the caves. Besides its karst features, it also used to be a military base for the local ethnic groups, with some military relics still remaining.
