Farmer Walked Into A Cave In The Forest And What He Discovered Left Him Speechless

Back in 1991 a Vietnamese farmer Hồ Khanh was wondering around the forest when he wandered into a cave he had never seen before. As he walked in, he was left speechless because of the size of the cave. At the time Khanh had no idea that he just discovered the biggest cave in the entire world. 18 years later a group of British scientists decided to landscape the cave and discovered an underground kingdom that was forgotten. Son Doong is the largest cave to have been discovered scaling at 3 miles long and nearly 500 feet wide. The cave is open to anyone wanting to explore it and located in Phong Nha-Kẻ Bàng National Park.
