The World’s Biggest Cave

 Both Cheryl & I get claustrophobic!  Not sure we could even go in here for very long despite how LARGE it is.

In 2009, a team of British cavers investigated a recently uncovered cave in a remote Vietnamese jungle. The Son Doong cave is enormous; can it be larger than the current world-record holder? The explorers traveled for miles through the cave before hitting a 46-foot-high wall. Now, follow the team as they return to Son Doong to finish exploring the cave and climb the wall. Will Son Doong prove to be the worlds biggest cave? And what secrets are undiscovered inside this unique ecosystem?

Also read the full article on Son Doong cave by Mark Jenkins in the January 2011 issue of National Geographic Magazine. But first, enjoy some of the beautiful pictures illustrating the natural beauty of Son Doong.

A half-mile block of 40-story buildings could fit inside this lit stretch of Hang Son Doong, which may be the world’s biggest subterranean passage. (Photo Credit: © Carsten Peter/National Geographic)
