A man named Ho Khanh found the cave when he was hunting for food during a storm. He went inside the cave and saw the underground kingdom inside it and was amazed by the new world he had discovered. However, Ho Khanh was not able to relocate the cave again until after 18 years of exploration.
Professional cave explorers Howard and Deb Limbert from the British Caving Research Association, together with Ho Khanh visited the cave which is now called Hang Son Doong. The cave was the largest one Ho Khanh had seen as it can hold an entire block of New York City.
The cave is said to be 3-miles big and many different kinds of birds, monkeys, and rare baseball-sized limestone cave pearls can be found inside. Because of its size, it is now proclaimed as the largest cave in the world. The cave has its own weather system, underground river and towering that is as high as 656 ft. This wonderful kingdom can be found in the deeps of Vietnam’s Phong Nha-Ke Bang National Park.
Because of its hidden beauty, many people want to visit the enchanted place however, only 500 tourists are allowed to enter the cave per year to preserve its natural beauty.
