Here is the mouth to the world's largest single cave passage found to date. It is the Son Doong cave in the dense jungles of Vietnam's Phong Nha-Ke Bang National Park.

The cave measures at least 262-by-262 feet (80-by-80 meters) in most places and is at least 2.8 miles (4.5 kilometers) long.

These are giant formations within the cave. Some of the giant stalagmites are more than 230 feet (70 meters) high.

Didn't we have pics of this cave a few months back? I could be wrong. I often am.

It was smaller before they built the Hanoi Highway.

This one? http://cellar.org/iotd.php?threadid=26847

You even commented on it. BTW - I have no illusions about Tolkien's imagination. They probably dug out the cave after reading his books.

I thought that cave was this cave. But IIRC, this one ain't really a cave, more like two mountains fell against each other. Venezuela, I think.

Please note the helicopters.
