Have you ever heard of a cave so massive that a Boeing 747 could fly through its largest cavern?
Or large enough to house an entire New York City block, including skyscrapers?
The Hang Son Doong cave has been determined to be the largest cave in the world. Hang Son Doong, which translates to ‘Mountain River Cave’, is found in the heart of Phong Nha Ke Bang National Park in the province of Quang Binh, Vietnam.
Despite its immaculate size, the cave was not discovered until 1991 by a local villager and was not explored at all until 2008, when the British Cave Research Association conducted the first expedition.
The cave consists of a long tunnel of over 5 kilometers. This tunnel was sculpted beneath the Annamite mountains by the powerful Rao Thuong river, which still flows through the cave. Hence the name ‘mountain river cave'.
The cave has collapsed in two places, forming giant sinkholes where a tropical rainforest grows, 400 meters beneath the surface. The cave also has its own climate, with misty clouds surrounding much of the area.
Hang Son Doong also contains enormous stalagmites of over 80 meters high, which are the tallest ever discovered.
Not many people have been inside the cave since it’s only accessible to the general public through pricey guided expeditions.
However, it's quite safe to say that this extraordinary place is worth going the extra mile for!
