The Son Doong cave is one of the world's largest, but until now you had to travel to Vietnam to experience its misty, majestic glory. National Geographic recently created a virtual tour of its massive tunnels and little jungles, so now you don't even have be wearing shoes to stroll inside.

The cave is over 5km long, with sections reaching up to 200 meters tall and 150 meters wide, and a total volume of 38.5 million cubic meters. National Geographic highlights certain cave features throughout the tour, like a giant stalagmite known as The Hand of Dog and a flush, green jungle nicknamed The Garden of Edam.
