A photographer has released stunning drone footage of the world's largest cave, located in Vietnam.
Ryan Deboodt shot the video in Hang Son Doong cave, with the largest chamber being 3.1 miles long, 660 feet high, and 490 feet wide.
Using a DJI Phantom 2 drone with a GoPro Hero4, Deboodt was able to capture amazing and unique views of the giant caverns near "skylight" areas 1.55 and 2.17 miles deep inside which have openings allowed sunlight to seep in.
The Hang Son Doong cave means "Mountain River cave" in Vietnamese and contains a huge fast-slowing underground river. The vast opening was only discovered in 2009, when it overtook Malaysia's Deer Cave as the largest in the world.
Tours of the abyss will set you back 64,500,000 Vietnamese Dong (US$3,000, £2,000) per person for a six night stay. It might be worth it, as the cave has a perfect five-star rating on TripAdvisor.
Deboodt is a cave, adventure, and travel photographer who lives in Beijing, China. Much of his work is focused on the Phong Nha Ke Bang National Park in Vietnam, where the Son Doong cave is found. To find out more, visit his website or follow him on Instagram.
