I have been to most of the show caverns in Virginia and none of them were self guided. I loved the fact that this one in West Virginia is self guided because you get to go at your own pace and explore on your own. You really do feel like you are an explorer. Because it is self guided, you do not get the history of the caverns (when it was found, the name, etc.), but you can ask the people in the gift shop. The caverns are small and it was wet and slippery in some parts (my pants got really dirty). You can actually rappel into the caverns (call for details). It should not take you more than an hour in the caves and a few minutes to look around the gift shop. The caverns are not wheelchair or stroller friendly. The women's rest rooms were spotless. The gift shop has many unique items at reasonable prices. The admission price of $12 is very good and they give a AAA 10% discount. There are also two alpacas in a fenced in front yard and several well behaved dogs around the property.
Only negative: The road to get to the caverns is a typical West Virginia back road (hard to find, long, twisty, full of pits, and unpaved).
