Shuanghedong (双河洞), is the longest cave in China,[1][2][3] the second longest in Asia[4][5], and 11th longest in the world[6][7] in 2017. It is located near the town of Wenquan in Suiyang County, Guizhou Province.[8]

This gypsum and dolomite cave has carbon dioxide levels of approximately 400ppm, with a constant temperature of about 13 degrees Celsius year round.

The cave contains numerous waterfalls, and at least three underground rivers, some of which contain cave shrimp, and fish weighing several pounds.[9] Also found, have been tadpoles, frogs, insects, spiders, bats, leeches, blind fish, and mushrooms.[5]

Since 1987, at least 20 expeditions from France and Japan have explored the cave.[10]
