One of the major caves in Wulong Karst area is San Wang Dong - fabulous 67 825 m long cave, which one day could be connected to the nearby Er Wang Dong cave (42 139 km), thus getting into the list of top 20 longest caves in the world.

Wulong karst

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. San Wang Dong is the longest known of these caves.

Giant cave

San Wang Dong is known for decades but intense exploration of the cave started just some decade ago. This exploration is organized by the international Hong Meigui Cave Exploration Society.

Cave has many passages formed by powerful streams.

Closer to its southern end cave crosses Shiwangdong tiankeng - up to 252 m deep sinkhole. It runs close to Taipingmiao and Daluodang tiankengs as well - most likely it is connected to these sinkholes but these passages still need to be found.

San Wang Dong cave runs very close to another giant cave - Er Wang Dong. San Wang Dong in general is located lower than the other cave - but it is possible that both caves are linked.

San Wang Dong is characterised by very impressive cave rooms and passages which are almost intact. Some of the most interesting ones are:

  • Cloud Ladder House - currently seventh largest cave room in the world. Area of this cave room is 51,158 m² - as large as eight football fields. Ceiling is more than 250 m high and volume is approximately 5.8 million m³. Mist rises from the stream and forms clouds which are trapped near the ceiling of cave room.
  • Crusty Duvets - 1.86 km long, spatious passage with giant stalagmites and countless gypsum crystals.
  • The Sea of Tranquility - enormous passage where nitrates were mined in the past.
  • Where The Wind Blows - narrow passage where the wind whistles through, carrying sand articles and dust.
  • Xinu Attix - amazing vertical pit.
