Amazing drone footage shows the world's largest cave, Hang Son Doong – ‘Mountain River Cave’ in Vietnam.
Son Doong cave(Vietnamese: Hang Son Doong) is one of the most beautiful natural caves and the largest ever found in the world. The name "Son Doong" cave means "mountain river cave" It is located in the Phong Nha-Ke Bang National Park, near the Laos–Vietnam border., about 450 kilometers (280 miles) south of Hanoi. Son Doong cave is the biggest cave in the world, more than 8.7 kilometers (5.4 miles) long and it has its own river, jungle, and climate! ->This may be the reason why the inside of the cave is not too dark! and there are also some plants found in the cave that makes the cave look more spectacular. You can even visit this cave at night because it is also completed with some lights.
