In 1991 a lost farmer, Ho Khanh, stumbled across what would turn out to be the largest cave in the world. When the farmer attempted to find the cave again, he ran into dead end for nearly 20 years! In 2009, with Ho Khanh acting as their guide, a team of British cavers re-discovered the cave and began a journey of exploration.
Located in Vietnam, the Hang Son Doong cave is over 200 meters wide, 150 meters high and 9 kilometers long. The cave is estimated to be between two and five million years old and it houses a diverse landscape, rich biodiversity, and incredible stalagmites that reach nearly 70 meters in height.
Hang Son Doong, which translates to “Mountain River Cave”, was formed when the subterranean river that runs through it ate away at the limestone of the Annamite Mountains, which it now lies beneath. Large holes in the ceilings of the cave were created during this process. These “skylights” allow sunlight into portions of the cave, creating a dense rainforest below the surface of the Earth.
