Ohio Caverns

Welcome to "Ohio's Outstanding Natural Wonder"


Ohio Caverns is the largest complex of caves in Ohio. In addition to being the largest cave in Ohio,
it is the most colorful cave in Ohio featuring a wide array of colorful stalactites and stalagmites and dual formations.

Ohio Caverns has two types of stalactite and stalagmite formations while most caves only have one type, made of Calcite. This forms the translucent white formations found in most caves but Ohio Caverns has another type of formation, made from Iron Oxide, more commonly known as rust. This is the predominant feature and color of the cave. Only a few known caves in the world have this type of dual formation.
