Wulong Karst Area is rich with magnificent scenery, including giant sinkholes and caves. The 42 139 m long Er Wang Dong cave (Cave of two kings) is one of the most impressive landmarks in this area.
The thick layer of Lower Ordowician limestone near Wulong is criscrossed by cave labyrinths. This limestone in some areas is covered with Paleozoic sandstone, helping to preserve it from erosion.
Some of the largest sinkholes in the world - such as the exotic Qingkou tiankeng - are located here and some of the most impressive caves in the world connect these giant sinkholes. Er Wang Dong is one of major caves here, running very close to the 67 825 m long San Wang Dong Cave.
Cave of two kings
Cave starts in the south-western side of the 195 m deep Niubizi tiankeng. The enormous cave has huge mass of air inside and has its own climate. These clouds appear also in Niubizi tiankeng. In fact these clouds serve for weather forecast - when in tiankeng appears fog, soon will come rain.
Cave reaches also Qingkou tiankeng - gargantuan sinkhole created by several waterfalls, which still fall into this 295 m deep sinkhole. The largest passage - Tiankeng Express - here starts from the exotic ecosystem in the bottom of tiankeng.
Er Wang Dong is complex cave with passages in several layers, numerous passages form a true maze.
The exploration of this cave is organized by the international Hong Meigui Cave Exploration Society. Cave is known to local people since ancient ancient times - in Er Wang Dong village it was used as source of potable water and as a storage site but far northern passages were used for nitrate mining.
Er Wang Dong cave runs very close to San Wang Dong cave. Er Wang Dong in general is located higher than the other cave - but it is possible that both caves are united.
