🏁 Our 4 Days in Indiana: Space Suits, Caves, and Racing Fun

🌎 A New State on Our Family Map

At home, we have a large U.S. map where we frame a photo from each state we visit together. Living in Wisconsin, we’ve already explored Minnesota, Michigan, and Illinois — but Indiana was new for us.

When my husband mentioned his love for Indy cars and I realized Indianapolis is home to the largest children’s museum in the world, the plan came together quickly. It was fall break, which made the timing easy. After a summer trip to Michigan’s Upper Peninsula — mosquitoes and all — we were ready for something a little more comfortable, but still meaningful.


🚗 Day 1: The Drive In (and an Unexpected Sunset Show)

We left Wisconsin on Friday afternoon and, as expected, ran straight into Chicago traffic. It was the usual mix of slow lanes and quiet patience — the part of road trips you just get through.

Then, almost without noticing, the scenery changed. Rows of windmills appeared across open farmland, turning steadily under a glowing sunset. The frustration of traffic faded. For a few miles, no one talked. We just watched the sky change colors and let the drive slow us down.

Travel Tip: If possible, plan around Chicago rush hour — or build in a dinner stop before the city.

🚀 Day 2: Exploring the World’s Largest Children’s Museum

Saturday was dedicated entirely to the Children’s Museum of Indianapolis, and it lived up to everything we’d heard. Five floors, countless exhibits, and the kind of energy that makes time disappear.

What stood out wasn’t just how much there was to see, but how naturally our little one moved from one experience to the next — less interested in displays, more drawn to anything that allowed pretending and exploring.

The space station exhibit quickly became a favorite. Watching our little one carefully adjust a helmet — as if a real launch were about to happen — was one of those quiet moments that sticks with you.

The dome theater, with its journey to the moon, offered a calm pause in the middle of a busy day. It was immersive without being overwhelming, which made it a surprisingly good reset.

The kids’ area on the third floor could easily fill an entire day. Water play, climbing structures, building toys, music instruments — it was the kind of space where everyone settles into their own rhythm.

Outside, the sports center pulled us all in. Floor hockey, T-ball, pedal cart races (with adult and kid sizes), and mini golf turned into one long stretch of shared energy. The giant treehouse covered in sports sculptures became a natural meeting point — climb, explore, return, repeat.

By late afternoon, the tiredness was unmistakable. We had planned to visit the zoo that evening, but traveling with kids teaches you to listen when energy runs out. We headed back, knowing the zoo would still be there tomorrow.

💡 Family Tip: We bought the Indianapolis 3-Day Pass, which is valid for 72 hours after first use. Even though it’s called a “3-day” pass, we used it across four calendar days. The key is timing: as long as you enter your final attraction earlier than the time you first activated the pass, it still works.

🎈 Day 3 Morning: Conner Prairie’s Balloon & Treehouse Adventure

Sunday morning felt quieter. We drove about 30 minutes to Conner Prairie, with one goal in mind: the helium balloon ride.

Floating gently above the park was calm in a way that’s hard to describe — no rush, no noise, just a wide view and a steady breeze. It was one of those moments where everyone naturally slows down.

We skipped most of the historical reenactments this time and focused on the treehouse playground instead. Shaded, creative, and open-ended, it gave our little one space to explore while we enjoyed a rare moment of simply watching.

🐆 Day 3 Afternoon: The Indianapolis Zoo — Big, Beautiful, and Worth the Walk

After lunch, we headed to the Indianapolis Zoo, and by the end of the afternoon my step count was hovering around 15,000.

What impressed us most was the sense of space. The cheetah exhibit stood out immediately. We waited, unsure if we’d see much — and then, suddenly, it ran. The moment was over almost as quickly as it started, but we all stood there for a second longer than necessary, quietly processing it.

The chimpanzee area spans three connected buildings with overhead tunnels, allowing the chimps to move freely between spaces. It felt thoughtfully designed — not just for visitors, but for the animals themselves.

The dolphin show was engaging and well done, familiar but still enjoyable.

Family Tip: Bring a stroller and water. The zoo is large, and the walking adds up faster than expected.

🦇 Day 4: Exploring Marengo Cave — A Cool Underground Adventure

Monday was our day to explore beyond Indianapolis. Indiana is known for its caves, especially in the southern region. Some offer underground boat rides in near-complete darkness — exciting, but maybe too intense for young kids.

We chose Marengo Cave, a well-lit and kid-friendly option, and it was perfect.

Before the tour, we bought toy hard hat with a headlamp for our little one — a fun, confidence-boosting touch. If you are planning a similar trip, something like this can really help.

Inside, the walkways were smooth and manageable, with stunning formations throughout. Backpacks and strollers aren’t allowed, but the walk is easy for little legs.

The highlight was the Cave Simulator, a big crawl-through maze box. Our little one got a bit lost at first but eventually emerged proudly with the help of older kids.

By the end, this underground adventure became the favorite part of the whole trip.

🏎️ Day 5: The Indy Car Museum — Racing to the Finish

Tuesday morning was my husband’s highlight: the Indianapolis Motor Speedway Museum.

When there are no races or practices, visitors can take a bus tour around the actual track. The speed is only about 25 mph, which sounds slow — and it is. But the slow speed makes something else very obvious.

The turns are heavily banked. At racing speeds, that banking probably disappears beneath you. But at 25 mph, you feel it. As the bus leaned into the curve, it was almost impossible to stand upright — everyone instinctively grabbed the nearest rail. It was a surprisingly physical reminder of just how fast Indy cars must be when the banking suddenly works for them instead of against them.

Inside the museum, the interactive area kept things fun and accessible: driving simulators, pit stop practice, and reaction-time games. Even without being a racing family, it was easy to walk away with a new appreciation for what happens on this track.

Family Tip: Check tour schedules ahead of time — the museum and track tours may close for race events or private bookings.

❤️ Final Thoughts: Why Indiana Surprised Us

Indiana turned out to be the perfect mix of city adventure and family learning. From space suits and pedal carts to cheetahs and caves, every day gave us something new to explore.

Indianapolis is clean, organized, and incredibly family-friendly. The 3-Day Pass made everything simple, and each attraction felt thoughtfully designed for kids and adults alike.

If we could change anything, we’d add one more day — either to revisit the Children’s Museum or stroll through downtown. But overall, this trip was exactly what we needed: fun, educational, and full of great memories.

And the best part? We added a brand-new framed photo to our family travel map — one state closer to our goal of visiting all 50 together.
