The largest cave in the world now on Virtual tour - let's explore it from your chair

Hang Son Doong (Mountian River Cave), the largest cave in the world, is located right in the heart of Phong Nha-Ke Bang National Park in the Quang Binh province of Vietnam. It was formed during the Cambrian-Permian geological eras, putting it at a date between 400–450 million years old. No words can do justice to the size of this UNESCO protected cave—it stretches for over three miles (five kilometers), and it reaches heights of 650 feet (200 meters). The main cavern is large enough to house an entire New York City block.
