Sơn Đoòng Cave (hang Sơn Đoòng, Mountain River cave in Vietnamese)[1] is a solutional cave in Phong Nha-Kẻ Bàng National Park, Bố Trạch District, Quảng Bình Province, Vietnam. As of 2009 it is the biggest known cave in the world,[2][3] and is located near the Laos–Vietnam border. Inside is a large, fast-flowing underground river. It is formed in Carboniferous / Permian limestone.[4] Sơn Đoòng Cave was found by a local man named Hồ-Khanh in 1991. The whistling sound of wind and roar of fiery stream in the cave heard through the entrance as well as the steep descent prevented the local people to enter the cave. Only in 2009 did the cave become internationally known after a group of scientists from the British Cave Research Association, led by Howard and Deb Limbert, conducted a survey in Phong Nha-Kẻ Bàng from 10 to 14 April, 2009.[1] Their progress was stopped by a large, 60 metres (200 ft) high calcite wall,[1] which was named The Great Wall of Vietnam. It was traversed in 2010 when the group reached the end of cave passage. https://youtube/watch?feature=player_embedded&v=SKAXw4mzgIo
