The overall length of Crown Cave is 12 km (7.5 miles). The 3 km (nearly 1.9 miles) near Li River has been developed and opened to the public. It is unique in ways of sight-seeing. First you can reach the mountainside by light rail and descend into the cave by elevator. There are altogether five caves. The stalactites, stalagmites and stone pillars inside will capture your imagination and make you want to linger. Then you can take the light rail to Palm Hall. The tallest palm-like stone pillar among the four in the hall is taller than 50 meters, reaching the ceiling of the cave. The ‘palm tree’ is so thick that it takes several people to put their arms around it. It is really a wonder! You can’t help but marvel at the magical power of nature. Then you can take a small boat to experience the distinctive views of the underground river. Many other karst landscapes are waiting for you after you go ashore from the boat. Crown Cave was listed in the Guinness World Records as a cave with the most ways of traveling.
