Fantastic Caverns is a show cave in Springfield where the whole tour happens aboard a Jeep-drawn tram, so you ride rather than walk. The route follows the path left behind by an ancient underground river. The cave was found in 1862 by John Knox and his hunting dog, and in 1867 twelve women from a Springfield athletic club became its first explorers, carving their names into the rock.
