The northern half of Ohio is a geological wonderland. Our landscape is highly unique, and the chemistry of our local sandstones has made many quarry towns in Northeast Ohio rather famous. But quarrying, it seems, is largely in our region’s past. Don’t dismay, though, because there is still one incredible way to experience the wondrous geomorphology of Ohio’s geological record:

Welcome to the largest underground caverns in the state of Ohio.

Robert S/TripAdvisor This stunning subterranean wonderland is just a short drive from Cleveland. Tucked away in Bellevue, this hidden world is well worth a visit at least once.

The caverns, which are a consistent 54 degrees Fahrenheit throughout the year, are a Registered Natural Landmark by the Ohio Department of Natural Resources.

The caverns were discovered in June 1872 when two boys chased their dog through a natural sinkhole.

Robert S/TripAdvisor When they fell into the dark room, it became apparent that they had discovered an underground world. The boys found and rescued their dog, and then they spread the world about their discovery.

In May of 1933, a local amateur geologist named Don Bell joined forces with the property owner to open the caverns to the public.

There are several levels of caverns hidden underground, with the lowest level revealing the top of the water table.

Seneca Caverns/Facebook The Ole Mist’ry River, as it is affectionately known, is actually not too mysterious at all. Its water is of good quality, and it rises at a rate of roughly one-foot per hour. Interestingly, it does pose one bit of a conundrum: as the water table rises, the water can get inside of light bulbs and floodlights, which are sealed at the factory.

From a fascinating geology to an unusual array of creatures that call such a habitat home, this system of caverns is truly breathtaking.

Tours are $17 for adults, $16 for seniors over 65, $14 for a Child Caveman Package (a tour plus a bag of gems that they get to “mine”) or $9 for general admission, and children under 5 are free.

Are you ready to experience one of Northern Ohio’s most spectacular wonders?
