All of the great wonders of the world have already been discovered, right?
Everyone knows about the Great Pyramids of Egypt or the Great Wall of China, but the world’s largest cave was undiscovered until 1991 when a local farmer stumbled across it.
The cave is part of Phong Nha-Ke Bang park which has entranced humans in the area for time untold.
There are over 300 caves and grottos throughout the park. Almost all of them are made out of limestone.
Researchers and explorers have only seen a small part of this massive cave system.
Why wouldn’t you want to explore this amazing hidden world?
The affect of millions of years of natural erosion have given the caves a surreal, alien aspect to them.
There is a wild variety of plant and animal life living within the caves, untouched or seen by mankind.
The caves are large enough that there are massive hills and mountains inside of some of them!
This cave is absolutely incredible.
