We found this cavern while looking for a campground in the Roanoke, VA area. We stayed at the campground that is onsite at the caverns and toured the caverns themselves.
The tour was great, and the features of the cavern were great as well! Here’s my review on Yelp: http://www.yelp.com/biz/dixie-caverns-and-pottery-salem?hrid=_WgYZTbQf1GKjxKWG-ynRA… and here are pictures we took:
