Description of Son Doong Cave


Son Doong Cave is a massive natural cave located in Bố Trạch district, Quảng Bình Province in Vietnam on the border with Laos. It is the largest underground system situated within borders of the Phong Nha-Kẻ Bàng National Park. Its name in Vietnamese is translated as "Mountain River cave" after an underground river that formed it for the past 2.5 million years. Son Doong Cave was discovered in 1991 by a local man named Hồ-Khanh, but it was was not explored until 2009 when a group of British speleologists from the British Cave Research Association descended here. An expedition led by Howard and Deb Limbert conducted an exploration of the underground tunnels and claimed it was much larger than Phong Nha Cave that was fought to be the largest in the country at the time. Parts of the ceiling have collapsed, opening huge skylights in the roof. This allowed light in allowing different species of plants to grow in this small ecosystem.

Son Doong Cave is barely explored, but it is probably the largest cave in the World. It reaches a depth of at least 150 m (490 feet) with a length of more than 9000 meters or 30,000 feet. It largest room measures more than 5 km in length, 140 meters wide and over 200 meters high. For more information you can read an article in the National Geographic.
