World's Biggest CaveThere's a jungle inside Vietnam's mammoth cavern. A skyscraper could fit too.

Hear author Mark Jenkins and National Geographic's Boyd Matson talk about what could be considered the largest cave in the world, the 2.5-mile Hang Son Doong, or mountain river cave, along the Vietnam-Laos border.

Is it the World's Biggest Cave? More than three times the height of Niagara Falls, much of Vietnam's Mountain River Cave has remained untouched by humans until now.

With exclusive footage, NGC reveals, for the first time in history, astounding evidence that this could be the largest cave in the world.

Together with renowned expedition leader Howard Limbert, cave geologist Darryl Granger uncovers the formula for how the cave grew so grand.

Raptor is right...it's not really a "documentary"...at all. And I did not get a sense of what it might be like being there...sure, we can see that it's an amazing place, but...that's about it.
I admire and respect the effort to produce this, but...it needs to be redone (and will be I'm sure)

@Bill Blankenship -- i think you are referring to a movie called Sanctum. It's not a doc, but it's based on a true story. good movie!

Yeah, not really a documentary is it? More like some European guy showing off his holiday snaps and appealing for funds. Wish I could get paid to go on vacation in Vietnam.

I'm looking for a documentary about some explorers who become stuck in a cave after it starts to rain so they have to find another way out.
It was early 90s when I saw it. Any ideas on where to look? anyone please??

I love it how NG always tries so hard to prove their "global warming" argument in all the new programs they produce. These new programs are half propaganda, half reality, since the Rockefeller foundation started funding them. Just tell us the facts NG, not your theories.

From someone who has only crawled through abandoned mines, this is awe inspiring.

Boring! Can't see hardly any of the cave just a load of people dithering around in the dark.
