Weirdest Natural Places: Son Doong Cave
It really wouldn’t be too far-fetched to come across a pterodactyl gently nesting inside this place…Located in Vietnam, near the border with Laos, Son Doong Cave is the biggest known cave in the world.
Just how big is it? Son Doong stretches for about 30,000 feet, and its biggest chamber is over 650 feet tall. To put that in perspective, we could put the Gateway Arch from St. Louis inside the cave and there would still be room on top. The cave was only just found in 1991, and it wasn’t until 2010 that people actually managed to reach its end. This is because of a giant, 200-foot-high calcite wall later named the Great Wall of Vietnam.
Would you like to visit it? Good news! You can…possibly. In 2013, the first tourist group ever was taken inside and more tours are now happening. All you need is years of spelunking experience and about $3,000 (plus the money to get to Vietnam and back).
