As awe-inspiring videos go, this is about as spell-binding as it gets. On the back of a drone, you weave your way through the world’s very largest cave, Hang Son Doong, which means “Mountain River Cave” in Vietnamese. This gorgeous cave is a yawning chasm within solid rock and, owing to the constant seepage of life-giving water into its belly, offers the local biology the most wonderful respite from the elements. As such and as you will see in this beautiful footage, life flourishes within the shelter of Hang Son Doong.
Keep an eye out for the people on the ground as the drone sweeps over the vast interior of the cave and you will develop a true appreciation of just how immense Hang Son Doong really is. If you want to see it for yourself, hop on a plane to Vietnam: Tân Trạch, Bố Trạch, Quảng Bình to be more precise.

How Was It Formed?
Hang Son Doong is a solutional cave formed in the calcium-rich limestone of the Phone Nka-Ke Bang National Park. Over the eons, a weak acid formed from the mixture of water and carbon dioxide gas released by plants (carbonic acid) has slowly eaten away at the alkaline rock, carving out this gigantic chamber beneath the mountainside. Hang Son Doong now houses its own rushing river, some of the biggest stalagmites in the world (70 meters tall) and a natural inner chamber that is in excess of five kilometres (or 3.1 miles) in length!
