We passed by Crystal Grottoes Caverns on our way to visit the battlefield at Antietam. It wasn't in our plan to visit the caverns but our family enjoys going to other caverns (e.g. Luray Caverns) so we decided to stop by on our way back from Antietam.
The building you arrive at isn't all that impressive as compared to Luray Caverns and was a bit hesitant when we arrived especially when I was told the price ($15 for adults and $10 for children).
We had a tour with Sonny who was very nice and knowledgeable about the formations. Our family essentially had a private tour since no one else was with us. We got to ask plenty of questions which we hadn't had the opportunity to ask at other caverns. Our six-year-old daughter liked being able to ask questions and get answers.
The tour lasted about 35 minutes which was about perfect for us after spending the day at Antietam. After the tour, I thought the entry fee was worth it.
