40-story skyscrapers would fit comfortably inside Son Doong, a breathtaking 5.5-mile long cave—reportedly the largest in the world—located in central Vietnam, and it’s open to the public for the first time. For $3,000, the cave’s original explorers can give you (alongside your porter) the grand tour around its jungles, river valleys and 260-foot stalactites. But only if you’re one of the first 220 adventurous travelers to book!
