World’s Biggest Cave?
In 2009, a team of British cavers explored a cave in Phong Nha-Ke Bang National Park, Central Vietnam. At that time, they explored 2.5 miles of the immense Hang Song Doong cavern before reaching a wall of muddy calcite.Tomorrow on the National Geographic Channel, the World’s Biggest Cave reveals what the team discovered when they returned a year later.
