Sơn Đoòng cave (Vietnamese: hang Sơn Đoòng, IPA: [haːŋ˧ ʂəːn˧ ɗɔ̤ŋ˨˩]), in Phong Nha-Kẻ Bàng National Park, Bố Trạch District, Quảng Bình Province, Vietnam, is the world's largest natural cave.

2024年8月27日 · The world’s largest cave, Hang Son Doong (Mountain River Cave) was discovered in the dense forests of Vietnam’s Phong Nha-Ke Bang National Park in 1990 by a local man, Ho Khanh, as he was seeking shelter from a storm.

Son Doong is considered to be the largest cave in the world, based on volume and also the biggest cave in Vietnam, found by Ho Khanh – a Phong Nha jungle man in 1990. In 2009, Hang Son Doong was officially surveyed and measured by the The British -Vietnam Cave Expedition Team led by Howard Limbert.

Son Doong is the biggest cave on the planet when measured by cross-section which is believed to be twice that of the next largest passage, in Deer Cave, Malaysia. This is relatively young at about 2-5 million years old in the Asian oldest major karst area dating back 400 million years of Phong Nha – Ke Bang National Park.
