nice cave, our tour guide didnt know how to talk. the farther in we got, the more uncomfortable we got.... dont bring your kids unless there comfortable around creepy, vulgar, adults who are frankly to old to be working there.
This isn't the greatest attraction in the Black Hills, but it's only like $5 for adults, lasted an hour, had a decent gift shop, an what made it really worthwhile was the guide. We were the only two on the tour, but the guide was just as energetic and friendly as if we'd spent $100 instead of 10. And if I remeber correct it wasn't too far from other attractions. Great for people who want a personalized cave experience.
