A modest farmer found an unknown cave in 1991 in Vietnam’s Phon Nha-Ke Bang National Park.
The man was so afraid of the deafening roar of water at the entry that he dared not investigate.
It seems that the choice to go deep within was only taken in 2009 by a group of British specialists. What did they find out?
There are lakes, clouds, and even vegetation and wildlife in the cave!
There are beaches with the finest sand in the world, little lakes with water like emerald, and a river that runs through the whole cave.
The pictures are amazing!
