Shuanghedong (Chinese: 双河洞; pinyin: Shuānghédòng; lit. 'twin rivers cave'), is the longest cave in China, in Asia, and the 3rd longest in the world as of May 2023.
It is located near the town of Wenquan in Suiyang County, Zunyi, Guizhou Province.
The cave contains numerous waterfalls, and at least three underground rivers, some of which contain cave shrimp, and fish weighing several pounds. Tadpoles, frogs, salamanders, insects, spiders, bats, leeches, blind fish, and mushrooms have also been found.
Since 1987, at least 20 expeditions from France and Japan have explored the cave.
In May 2023 the network reaches 400 kilometers of development.
