Ohio Caverns is a must-see natural attraction and a one of a kind experience. The caverns are absolutely stunning, beautiful, and colorful, with formations from millions of years of geological activity. Pictures do not do this place justice. There are two different tours: the historic tour and the natural wonder tour. Both are highly recommended, especially the combo tour which offers a large discount. The tours are very different, each providing a knowledgeable and fun experience where you learn so much. The tour guides are awesome, caring, down to earth, and make the experience pleasant. The grounds are really nice with easy parking, clear labels, a picnic place, and an area for kids to play. The park is entirely solar powered. It is an absolute blast and a highly recommended visit.
