 The History of Discovery of Song Doong Cave

 Song Doong means Mountain River in Vietnamese and the history goes like this of its discovery. A local farmer, Ho Khanh discovered this in 1990 when he was seeking shelter from a passing storm in the jungle. He saw clouds and the sound of an underground river coming from a large hole in the limestone. He reported all this to the British Caving Research Association (BCRA), who were in Phong Nha at the time. However, he lost the way and forgot the exact location and the cave remain undiscovered for the next 18 years. Again in 2008, Ho Khanh again while hunting for food stumbled across the entrance, and this time he returned with Howard and Deb Limbert from the BCRA.

Since 2008, the exploration has started but still many part of the cave remain untouched and a secret to outsiders.
