... Well, inside a cave, of course!
My original plan was to visit the famous Luray Caverns during a trip through the picturesque Shenandoah Valley, but discovered another nearby option through an Internet search: Grand Caverns.
We left our hotel with a plan to arrive around when the attraction opened at 10am (9am during the summer months) and I'm glad we did. The "Grand Caverns" are located inside a state park, and I wish we had planned even more time to explore the park's trails and, if it had been summer, I would have enjoyed the bargain-priced public outdoor pool ($4 per person 3 and up).
The tour begins up a hill inside a small museum (dated, not flashy, but my crew of boys enjoyed it) then a knowledgable guide gathers any tour guests on the hour. Courtesy jackets were available for anyone who forgot one because it is a chilly 54 degrees under ground!
Our guided journey, just over an hour in length, went far beyond the "this is a stalactite" and "this is a stalagmite" speech that I was expecting. Our guide was perfect, but the caverns themselves are absolutely captivating.
