"Caves are cavernous and scary places, filled with bats, bottomless pits, and other natural mysteries. In Vietnam, some brave explorers have discovered and mapped the world’s biggest cave. The Son Doong cave is 262 feet wide throughout most of the passage, and features a 1.6 mile long river and 230 feet stalagmites. For a couple of miles of the passage, the cave measures 460 feet wide. A local farmer discovered the cave and led the joint British and Vietnamese exploration team in their April expedition. The team mapping the cave got as far as a 46 foot high wall before they were stymied. “The second team that went in got flooded out,” Adam Spillane, a member of the British Cave Research Association expedition that explored the limestone cavern, said. “We’re going back next year to climb that wall and explore the cave further.” The previous record-holder, Deer Cave on the Malaysian island of Borneo, is 300 feet wide, but it is much shorter than Son Doong. The Vietnamese terrain, which is filled with similar limestone caves, presented a lot of difficulties to the explorers. The research team surveyed the cave using precise laser technology to assess its size." - vijay from Bookmarklet

Wasn't this cave a full scale NVA base with hospitals and depots used during the Vietnamese wars from 1950's-1975? - Bluesun 2600

Dude! Batman needs to relocate! Joking aside, this would be fun to explore. - darnell from BuddyFeed

LOL Bluesun! - vijay

Good thing I'm close to Vietnam right now. I'll have to make vacation plans. Details? Is it open to the public? Are there tours? - Bradley Farless

aye darnell! That would definitely be fun. Waterfalls and caves are two things that fascinate me the most - vijay

TalesOC, definitely not open to public! There's heavy chance to flooding; look what happened to the second team that went in. - vijay

Well, that's not very fun then. -_- I think I heard about a cave system in Sabah that's tourist friendly. Might check that out instead. - Bradley Farless

It's beautiful as well as huge. I can't wait to see a documentary on it. - Michael Fidler

I want to go there! - Craig Shipp

Wow! - Kol Tregaskes
