This summer, why not take your family to an attraction millions of years in the making? That’s right: It’s time to don a hard hat and go cave exploring. (Don’t worry – you don’t have to have your own hard hat; they’re provided for visitors!)
The twisting passageways of many of these caves in the Midwest come from thousands of centuries of groundwater seeping into limestone beneath the surface, dissolving it.
Then, as the water table lowers, the passageways remain, revealing narrow tunnels and soaring caverns just waiting to be discovered. (Most of the caves on this list were formed in this way, but not all.)
For your family’s next adventure, there are plenty of caves and experiences to choose from – whether your child wants to belly crawl through tight caverns, hike from one shallow cave to another or even take a boat ride right through a cave.
Here are some of the Midwest’s popular caves – and what you’ll find during your visit to these million-year-old wonders.
Be sure to bring your jackets, as many caves get a bit chilly!

To add to the appeal of this natural formation, there’s a waterfall that goes over the cave’s edge. Picnic areas are available nearby.

Bluespring Caverns was discovered in the 1940s when a farmer’s pond disappeared overnight – only to reveal the series of caverns just below the surface.
Today, visitors take an 800-foot steep ramp to get into the caverns and to where the boats are docked. A guide then takes you on an hour-long boat ride along Myst’ry River, which flows through the caverns, pointing out rare fish that call the caverns home.

Twin Caves is just one of several attractions located within the Spring Mill State Park. The park houses four interpretative facilities where families can learn about early pioneer life in the area, including a pioneer village of approximately 22 buildings, like a blacksmith, leatherworker, and operating gristmill. But for cave fans, there’s a 20-minute boat tour that takes visitors 600 feet into a cave – where you might be able to spy the rare, endangered blind cavefish and other creatures.
Reserve a spot at the inn or campground, too. Note: Reservations for cave tours are available on a daily basis, so staff suggests getting tickets early that day; once the daily slots are filled, no more tickets are sold. Tickets are not available in advance. Must show in person.
