Amazing footage of the world’s largest cave

This cave was first discovered in 1991, but only explored for the
first time in 2009 by a team of scientists from the British Cave
Research Association. What they found was that the limestone cave was
far bigger than expected. 

So big, in fact, that it’s the biggest known
cave in the world, with its largest chamber measuring more than 5 km
long, 200 metres high and 150 metres wide. The cave also contains some
of the tallest known stalagmites in the world, which are up to 70 m
tall. That’s like… a 20-storey building.
Obviously it’s pretty
hard to get aerial shots of an underground world – just imagine flying a
helicopter in there – but Deboodt managed to do just that using a
drone. The video was filmed
near the entrance of the first and second skylights of the cave, which
are 2.5 and 3.5 km inside the cave respectively, as Deboodt writes on his Vimeo page.
The
result is pretty damn other-wordly, showing forests, hills,
cliff-faces, streams and stone ridges, all buried deep underground. Look
closely and you can see people exploring the jungle and rocky outcrops
of the cave, dwarfed to the size of ants by the sheer scale of the
cavern.
The cave even has its own climate system, and you can see
mist rising off the forests in the footage. We don’t see any traces of
solid clouds in this video, but the smaller Er Wang Dong cave system in southwest China has its own weather, and we imagine Hang Son Doong is pretty similar.

In fact, the footage above
even makes the thought of living inside a cave somewhat palatable and
un-claustrophobic. We’ve now got a new ideal spot to run to if a zombie apocalypse breaks out
