Stark Caverns offer daily guided tours that last one hour and take visitors through four levels of the cavern, showcasing geological formations, Native American artifacts, and ancient “bear beds” where bears once hibernated. Along the way, you can see stalactites, stalagmites, soda straws, flowstone, and helictites, as well as one of the largest specimens of stromatolite fossils in North America. Within the cave, you will also encounter Moonshiner’s Dam, a historic site that reflects the cavern’s use during the Prohibition era.
