The cave's interior is China's only pure-white, jade-like example. It continues to expand due to erosion in the surrounding karst landscape. 1,644 metres (5,394 ft) long, of which 1,161 metres (3,809 ft) have been explored,  Snowy Jade Cave is spread over three levels. Inside, both the 8 metres (26 ft) Stone King's Flag (石旗王) and the 4 metres (13 ft) high Stone King's Shield (石盾王) features are the largest of their type in the world. There are also numerous examples of corals.
