There Is an Underground Cave in Vietnam's Forests That No One Has Ever Heard of
The discovery of Son Doong dates back to 1991, when a farmer stumbled across it while wandering around an unexplored cave in the Phon Nha-ke Bag National Park in Vietnam.
The farmer was scared off by gushing water from one of the cave’s entrances and no one visited Son Doong, which means ‘mountain river cave’, for 18 more years.
In 2009, Howard Limbert and a group of British scientists went on a cave expedition to Son Doong. And they were completely amazed by what they found. Not only was it the world’s largest cave, it was practically like an underground kingdom, a whole world with its own lakes, clouds, flora and fauna!
