Vietnam’s Son Doong Cave, which has a large fast-flowing underground river inside, was found by a local resident named Ho Khanh in 1991.

The cave became famous after a group of British scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted a survey in Phong Nha-Ke Bang which was recognized as a UNESCO World Heritage Site in April 2009.

According to Limbert, Son Doong Cave is five times larger than Phong Nha Cave which was once considered the biggest cave in Vietnam.

The largest chamber of Son Doong is more than five kilometers long, 200 meters high, and 150 meters wide.

With such large dimensions, Son Doong has overtaken Deer Cave in Malaysia to take the title of the world’s largest cave.
