Wulong karst

Located in Chongqing Municipality, the Wulong karst is a constituent part of the UNESCO World Natural Heritage site known as the South China karst. This area is characterised by a plateau-gorge karst landscape, which developed in Paleozoic carbonate rocks. Over 200 km of cave passages have been documented within this system, including the San Wang Dong and Er Wang Dong caves, which rank as the second- and fourth-longest caves in China, respectively.
The region features three distinct cave levels formed at different elevations, ranging from 660 to 1020 metres above sea level. This geological evolution also produced the Houping Tiankeng cluster, an assemblage of giant collapse dolines. Within this same complex lies the Longshuixia Fissure Gorge, a narrow ground crack sculpted by orogenic movement and water erosion over tens of millions of years. The gorge extends for approximately 5 km, with depths reaching 200 to 500 metres and a minimum width of only 2 to 3 metres in certain sections. A walkable trail of about 2 km, consisting of cliff-side plank paths, descends past the Yinhe Waterfall (also known as the Milky Way Flying Waterfall), which drops roughly 80 metres from the cliff face. An 80-metre sightseeing elevator provides access into the fissure.
