Arrived at 10:30 AM. Closed. Hanging sign was propped between the doors advising they would return at 2:15 PM. We couldn't accommodate a 3 hour delay. We will never return, since they are apparently actually open only by chance.

Okay attraction but pricy. Luray and Skyline are a much better value and worth the drive. The guide was knowledgeable.

I would say they are not. There are some narrow passages and a pray wouldn't fit through. There are also steps leading down to th cavern. I agree that a child under 4 or 5 might enjoy it for a little while but since they... More
