On the east bank of the Li River, the north side of the Crown Cave is close to the Caoping Village.

It is a cave of the Crown Hill under the water. In the distance, it looks like a purple golden crown.This is how the hill and the cave got their names. It is a wonderland of various stalactites, stone pillars and rock formations. It was opened to tourists in 1995 and is fitted with illuminating lights, a sound control tour guide system and elevators. Tourists are able to see all of the most interesting areas by specially designed trams and boats.
