PHONG NHA-KE BANG NATIONAL PARK, Vietnam, March 18 (UPI) -- A photographer created a virtual tour of the world's largest cave, Vietnam's Hang Son Doong, using a GoPro camera attached to a drone.
Ryan Deboodt, who posted the video to Vimeo, said the "otherworldly journey" through the cave was filmed both by hand and using a drone-mounted GoPro camera.
"Filmed near the entrance and the first and second dolines (skylights) which are 2.5 and 3.5 km [1.6 and 2.2 miles] inside the cave respectively," Deboodt wrote in the video's description.
The video was shot during a January trip organized by Oxalis Adventure.
"We were lucky enough to catch the most spectacular sunbeam show that I have ever seen," Deboodt said on Facebook.
