Back in 1991, a regular farmer in Vietnam found a new cave in Phon Nha-Ke Bang National Park. He got scared because of the loud water sounds at the entrance and didn’t check it out.
In 2009, a group of experts from Britain decided to explore the cave. Guess what they found? Inside, there are lakes, clouds, plants, and animals!
The cave has beautiful beaches with super fine sand, small lakes with emerald-like water, and a river that goes all the way through. The pictures of it are really cool!
