Farmer in Vietnam discovered a cave behind a rock—then he realized there was a whole world growing inside

In 1991, a farmer in Vietnam named Ho Khanh saw a strange rock on a mountain and took a look. Much to his surprise, behind the rock was the entrance to a large cave—and it was much larger than what he assumed on first glance.

In fact, the Son Doong cave is the largest cave in the world, spanning 5 kilometers long and 200 meters high. The biggest stretch of this large cavern is so big it can hold an entire New York City block.

Inside the cave is an entire rainforest; so large it has its own weather system.

There is even a beach.

The steep climb required to enter the cave prevented the wonder from being widely known. But then in 2009, people from the British Cave Research Association formally explored and publicized their findings.

One of the only things I regret about my trip to Vietnam was not looking more into seeing #hangsondoong

It wasn’t until 2010 that the cave was fully explored.
