World's largest cave is so big you can fly a Boeing 747 through it

The world's largest cave is so big that a Boeing 747 could fly through its largest cavern unscathed. It could fit a Manhattan city block complete with 40-story skyscrapers and has its own weather system that creates misty clouds hanging right above you.

And it wasn't explored until 2009.

Despite all of our recent advancements in technology, the Hang Son Doong cave in Vietnam was not even encountered until 1991, millions of years after its creation.

A local man found it in in the remote Phong Nha Ke-Bang National Park but he wasn't able to enter it due to the 80 meter drop that requires explorers to repel down jagged stone walls.

It wasn't for another another decade and half when he returned with a team of British explorers who plunged down into the total darkness and found the natural wonder.

The cave stretches back over 5 miles, complete with a river cutting through the stone. The Hand of Dog stalagmite stretches over 70 meters high and is thought to be the tallest in the world.

VIETNAM - UNDATED: ***EXCLUSIVE*** The British caving team crossing one of the underground rivers inside the Hang Son Doong cave in Ke Bang Massif, Vietnam, April 2009. A British Caving team believe they have discovered the largest sized cave passage in the world. Measuring 200 metres in height and 150 metres in width the new cave, called Hang Son Doong (Mountain River Cave), is 6.5 km long. Assisted by representatives of Hanoi University of Science the team explored the new cave for five days. The team spent six hours trekking through the jungle to reach the cave. Climbing down into a large chamber, they had to negotiate two underground rivers before reaching the main passage of the Hang Son Doong. The team will return to Vietnam later in the year to complete the expedition of the cave and conduct a full survey.

A collapsed hole in the wall of the limestone cave allows sunlight to flow through the cave and rich jungle vegetation to grow within, giving it is a distinctly 'Jurassic Park' feel.

Scientists have already found two new species within the cave that were forced to adapt to the lack of sunlight and isolation.

Vietnamese authorities granted tourist access to the cave in 2013, but right now there is only one company that guides visitors. Oxalis charges $3,000 per person for a 5-day experience that involves camping deep within the cavern.

The high costs have keep the site pristine, but for those who cannot experience it first-hand, check out the unbelievable 360 degrees panorama journey created by the National Geographic.
