Vietnam is home to the world's largest cave. Hang Son Doong is so unique that it has its own wildlife and ecosystem. Just one of its many chambers is 660 feet high and 490 feet wide. If you still can't comprehend that, imagine a cave so immense that it has its own microclimate with jungles, a river, and even beaches that you have to go cave exploring through miles of darkness before skylights in the ceilings shine light on the enclosed, hidden beauty around you.
Amazingly, a cave so huge was not even discovered until 1991 and very few expeditions have been launched to try to map it. Photographer Ryan Deboodt, however, became enchanted by Hang Son Doong and decided to film it from a perspective no one has seen before - from the air using a camera mounted on a drone.
