Deep in the jungle along the Vietnam-Laos  border, this exquisite cave was accidentally

discovered in 1991 by a local man trying to  get out of the rain. Its discovery was only

announced in the West in 2009.

At five kilometers long, 200 meters high and  150 meters wide, Son Doong overtakes

Deer Cave in Malaysia to take the title of the  world’s largest cave.

Best if watched in Full Screen mode.
