Like others, I remembered Howe caverns from my childhood= 1950's and my daughter's trip 1970's. and now we took my granddaughter. age 8 We had a great time. The tour was fun and educational. We had a picnic on the lawn and then she sifted for gems..There were plenty in the small bag so there was great excitement with each find. It was well worth the trip. Didn't do the zip line, but looked like fun. Granddaughter has already planned trip with her parents.
