Vietnam’s Hang Son Doong (mountain river cave)

Found this crazy-cool cave on National Geographic’s website. The vast size of this cave is mind-blowing. Just check out how tiny the people are in this photo – and this is only the mouth of the cave – it gets bigger and includes underground jungles too.
