A mapping team used lasers to measure the Miao Room chamber, and found it’s about 10% bigger in volume than the Sarawak Chamber in Malaysia, which was recognized as the world’s largest cave chamber.
While the Miao Room has the biggest volume at a whopping 380.7 million cubic feet, the Sarawak Chamber is still bigger in surface area at around 1.66 million square feet. That’s about 29 American football fields!
Located in southern China’s Gebihe cave system beneath Ziyun Getu He Chuandong National Park, the Miao Room can only be reached via an underground stream.
Take this amazing 3D tour of the system to get a sense of just how huge the cavern is!
