World's Largest Cave

This is amazing...

An astonishing 80 by 80 metres in most places, a local farmer led the joint British-Vietnamese expedition team to the cavern openening which he had personally discovered a few years ago.

Explorers of the cave walked 2.8 miles into Son Doong cave, in Vietnam’s Phong Nha-Ke Bang National Park, before being stopped by seasonal floodwaters. In the dry season it is thought they could have walked much further. What an amazing privaledge to have been any part of this team.
