Vietnam’s Son Doong is one of the world's largest caves, filled with underground rivers, jungles, stalactites and chambers large enough to fit a Boeing 747. Now visitors can wander the cave virtually thanks to a new video taken by a drone.

Discovered by a local explorer in 1991 as he trekked through central Vietnam's Phong Nha-Ke Bang National Park, the cave—whose name translates as "mountain river cave"—is absolutely massive. According to National Geographic, some of the cave’s largest passageways measure in at about 300 feet (91.4 meters) wide and over 600 feet (182.9 meters) tall. Some perspective: That’s wider than some New York City blocks and taller than many of the city’s skyscrapers. The cave is so expansive that some have called it an "infinite cave” because it seems to go on forever.

You no longer need to be a spelunker—or even strap on any safety gear— to explore Son Doong. A new video posted by travel photographer Ryan Deboodt reveals the cave in all its “infinite” glory.

To capture the video, Deboodt, outfitted a drone with a GoPro camera and flew it through the massive limestone cave. The result is a jaw-dropping tour of an incredibly beautiful and mind-boggling natural wonder. In short, the video is the best of armchair travel—and will undoubtedly inspire many to book tickets to Vietnam to explore the cave in real life.
