WATCH: Drone Captures Jaw-Dropping Footage Inside World's Largest Cave

Hang Son Doong in Vietnam is the largest cave in the world. It's more than 5.5 miles long, comes complete with its own jungle and river and is so gargantuan that it could apparently hold an entire block of 40-story skyscrapers within its walls.

In this video, created by photographer Ryan Deboodt, embark on an aerial and ground tour of this stunning cave. Drone-captured footage gives a glimpse into the world within -- from otherworldly rock formations to the cave's lush fauna.

The video has been viewed more than 570,000 times since being uploaded last week. Watch the clip above.
