Based on volume, the largest single cave chamber is the Miao Room – part of the Gebihe cave system in Ziyun Getu He National Park in Guizhou Province, China. The chamber was mapped with 3D laser scanners by a British-led geology team, funded by National Geographic, in 2013 and was subsequently calculated to have a volume of 10.78 million cubic metres (380.7 million cubic feet). The measurements were announced at the Hidden Earth 2014 national caving conference, held in the UK from 26–28 September 2014.
The Miao Room cavern was first documented by a Chinese-European geology team in 1989.
The previous record holder, the Sarawak Chamber in Gunung Mulu National Park, Sarawak in Malaysian Borneo, is about 10% smaller in volume than the Miao Room, however it retains the title of largest single cave chamber by area, with an approximate surface area of 154,530 square metres (1.66 million square feet) versus 140,540 square metres (1.51 million square feet) for the Miao Room.
The Miao Room also features some of the tallest stalagmites in the world, standing up to 45 metres (148 feet) tall.
