In Vietnam’s Phon Nha-Ke Bang National Park in 1991, a simple farmer discovered an unexplored cave.
The man was terrified and did not dare to investigate it since a terrifying roar of water greeted him at the entrance.
It appears that a team of British experts just made the decision to travel deep inside in 2009. What did they discover? A fantastic, self-contained world of 5 kilometers long and 150 meters wide. They confirmed that Soon Dong is the world’s biggest cave after examining the area.
There are lakes, clouds, and even vegetation and wildlife in the cave! You have to descend 80 meters on a rope before you can enter 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 following pictures will leave you speechless:
