The central scenic zone consists of a cluster of water karst caves. The 5,000-m-long tunnel is a gallery of stalactites and stalagmites of the most imaginative forms, hence it is known as "No. 1 water karst cavern on earth". The Dragon Palace, 15 kilometers (9 miles) in length, is the prime attraction. It is the longest karst river cave in China. The Guest-Welcoming Cave, the Dragon Gate Flying Waterfall, the Heavenly Lake, the Clamshell Rock and the Crystal Palace are its components.
