Crystal and Fantasy Caves are the parish's star attraction, two neighbouring limestone caves with clear underground pools, bridges, stalactites, and stalagmites. Crystal Cave is the better-known one, while Fantasy Cave is often the more colourful and less worn-feeling of the pair.
The caves are easy to combine on one ticket and make a good wet-weather stop, though they are popular enough that arriving early helps. The water is part of the magic: still, blue, and clear enough to make the formations seem suspended.
