The Hang Son Doong cave in Vietnam is so massive the Empire State Building could fit inside. It's about 3 miles long and 660 feet at its deepest point. Recently Beijing based photographer Ryan Deboodt used a drone and a GoPro camera to get a view inside and above the cave. Check out the video below.
An underground river river eroded massive amounts of limestone from underneath a mountain, which collapsed creating massive skylights. The cave was named the largest in the world after a 2009 expedition to survey it by the British Cave Research Association.
