The world's now-largest cave, located in Vietnam, is so tall and so wide that entire buildings and streets could be built inside them. The Son Doong cave will officially be open for public visits beginning next year, including spending three nights inside the cave starting from $3,000.
The cave is a whopping 9 kilometers in length, 200 meters wide and 150 meters tall. Now considered by the British Cave Research Association to be the largest cave in the wall, eclipsing the Deer Cave in Sarawak, Malaysia, the humongous cave has its own jungles, river paths and its own cave ecosystems dwelling within.
The Son Doong cave, situated in Phong Nha Ke Bang in the Quang Binh province, was first discovered by a local named Ho Khanh in 1991. But because he had found the cave when he was a child, he had forgotten how to reach the cave again, with many disbelieving his story of the epic cave. A British expedition team, led by Howard Limbert, then stumbled upon the cave and fully uncovered it in 2009.
