We took this tour with 2 small children (ages 6 and 10) and they really enjoyed the underground portion of the tour. It was a bit long (lasting 2 1/2 hours), but George, our tour guide, was very knowledgeable and very entertaining. I thought the most interesting part was about Over The Rhine and the breweries - could have skipped most of the church bit, but that's just my opinion. Overall, I would recommend this tour!
