“When do tours start?”

During the busy season (Memorial day weekend through Labor day weekend), Natural Wonder tours can start as frequently as every 10 minutes and the Historic tour as frequently as every 20 minutes but starting times depend on daily staff size, number of visitors/groups and other factors. Last tour is at 5:00 pm. Tours are limited to 20 people. When busy, tours begin to fill up quickly and wait times increase. On rare occasions tours can sell out.

During the off-season (October through April), Winter tours start less frequently. Wait times depend on daily staff size, scheduled groups, number of visitors and other factors. School group season is usually late September through early November in the Fall and late March through the end May in the Spring.  Last tour is at 4:00 pm. Tours are limited to 28 people.

“Do you close because of weather?”

We’re open even if it is raining! Lightening and heavy rain will delay the start of the Natural Wonder tour. Otherwise, tours run daily no matter the weather. 

“Can we use a stroller?”

We do not recommend using strollers, as the pathway is too narrow in many parts of the caverns. Chest baby carriers or back carriers work great.

“Are pets allowed in the cavern?”

Pets are not allowed in the cavern. However, certified service animals are permitted. 

“Are the caverns wheelchair accessible?”

The Limestone Tour is especially for guests with limited mobility. There is an admission fee for this twenty-five minute tour. Reservations are required for the Limestone Tour. Please call 937-465-4017 to schedule this tour. The Limestone Tour is offered from May 1 – September 30.

“How do you purchase tickets?”

You can purchase tickets online (Purchase Tickets) or upon arrival. Online tickets are good for any day and must be validated at the ticket counter.  Online tickets expire one year from date of purchase. Arrive early to avoid longer wait times!

“Is food and drink permitted?”

It is not permitted to bring food and drink in the caverns. We do sell snacks in the gift shop and you are welcome to bring a picnic to enjoy in the park.

“Do you offer a group discount?”

Groups of 20 or more receive a discount with a reservation. If you have 20 or more people in your group, please call (937-465-4017) a couple of weeks in advance to schedule a reservation.

“What to wear in the cavern?”

The temperature in the cavern is always 54 degrees so bring a jacket or sweatshirt. It is a concrete path so all shoes are fine, but closed toed shoes are recommended.

“Is photography allowed?”

Flash photography is welcome. Video recording, tripods, monopods and selfie sticks are not permitted. Tours are guided, so you will need to stay with the tour group.

“Are there steps?”

The Natural Wonder tour has a ramp entrance and 60 steps up to exit.
The Historic has 44 steps down to enter and 38 steps up to exit.
The Winter tour has 38 steps down to enter and 60 steps up to exit.
The Limestone tour (handicap accessible) has a ramp to enter and exit.

“Do you have to pay to park?”

Parking is FREE every day except on Monday, April 8, 2024 when you’ll be required to purchase a Darkness Tour ticket for everyone in your vehicle to enter the park. Someone will direct you where to park that day. 

Complimentary Hybrid and EV charging is also available. Once the main parking lot is full you may park just off the main driveway in the grass.

What Are People Saying About Us?

Do the combo pack; it is the best way to see the entire cavern. One is mostly history and the other is mostly formations but each gives you a different perspective. This is one of the most colorful caverns I have ever been in; it really is neat. Amie S.
Took the Natural wonder tour with a group on a 4H trip. Kids enjoyed the sites, staff was very friendly and tour guide was very good at keeping things interesting for the kids. Overall it was a good experience. Daniel C.
