The cavern is named for a large room toward the back of the cave tour, but this 'wet' cave has stalactites, stalagmites and columns throughout the entire 3/4-mile length. Cement stairs and walkways are fairly easy to traverse, and the two-hour tour is well lighted. A guide takes you through the cave in groups up to 100, but there is no sound system, so staying close to the front is the best strategy.
If you go:
Tours start at 10 am and the last one goes in a 4 pm. The fee is relatively high, but it is worth it for what is inside the cave. all areas are wheelchair accessible.
