How to Get There & Where to Stop
Planning the journey is just as important as planning the destination. With nearly eight hours of round-trip driving, you’ll want to be prepared and know the best places to stretch your legs.
Driving from Indianapolis (The Only Realistic Option)
Let’s be clear: driving is the only feasible way to conquer this as a day trip. Public transport options like Greyhound or Amtrak simply take too long to fit into a single day. The route is a straight shot west on I-70. To make the most of your time, we strongly recommend leaving Indianapolis by 6:30 AM EST at the latest. This gets you into St. Louis (which is in the Central Time Zone) around 9:00 AM CST, just as attractions are opening.
The Best Place to Stop Between Indianapolis and St. Louis
Breaking up the 4-hour drive is key to staying fresh. Here are the best spots right off I-70:
- For a Fun Photo Op: Casey, Illinois. You can’t miss this stop. Home to a quirky collection of “World’s Largest” items, including a massive Wind Chime, Rocking Chair, and Mailbox. It’s the perfect 20-minute leg-stretching break to snap some fun photos and marvel at the roadside kitsch.
- For a Quick Bite & Culture: Terre Haute, Indiana. As the unofficial halfway point, Terre Haute is a great place for a real break. Skip the fast food and pop into the Clabber Girl Bake Shop Cafe for a fantastic coffee and a fresh pastry to fuel the rest of your drive.
Top 3 St. Louis Attractions for a Day Trip
You can’t see everything in one day, so don’t even try! The key to a successful St. Louis one day itinerary is to prioritize. This “bang for your buck” trio gives you the perfect taste of the city’s history, culture, and fun.
-
Gateway Arch National Park
No trip to St. Louis is complete without visiting this iconic, 630-foot monument. More than just a photo op, the tram ride to the top offers breathtaking views of the city and the Mississippi River. The recently renovated museum at its base is world-class and included with your park entry.
- Cost: Park grounds are free. Tram Ride to the Top is ~$15-$19 for adults (dynamic pricing for 2025).
- Time Needed: 1.5 – 2 hours.
- Insider Tip: YOU MUST BOOK YOUR TRAM RIDE IN ADVANCE ONLINE. Tickets sell out, especially on weekends and during peak season. Booking a slot for around 10:30 AM or 11:00 AM is ideal for this itinerary.
-
Forest Park (Home of the FREE St. Louis Zoo)
Did you know Forest Park is larger than NYC’s Central Park? It’s a stunning urban oasis that houses five major cultural institutions. For a day trip, the main draw is the incredible St. Louis Zoo, widely considered one of the best in the nation. Best of all? General admission is completely free!
- Cost: Free admission! Parking is ~$15 per vehicle, though free street parking can be found.
- Time Needed: 2 – 3 hours.
- Insider Tip: The zoo is massive. Don’t try to see it all. Pick a section that interests you most, like the engrossing Primate House or the lively Sea Lion Sound, to explore without burning out.
-
The City Museum (If You Have the Energy)
This is not a museum in the traditional sense. It’s a 10-story jungle gym, an artist’s dreamscape, and an architectural marvel made from reclaimed materials. You can crawl through winding caves, zip down a 10-story slide, and explore a rooftop with a Ferris wheel. It’s a high-energy alternative to the zoo.
- Cost: ~$20-$25 per person.
- Time Needed: 2+ hours (it’s easy to lose all track of time in here).
- Insider Tip: This is best for active travelers and families with older kids (6+). Wear closed-toe shoes and clothes you don’t mind getting a little dirty. It’s an unforgettable experience, but not the best choice if you’re looking for a relaxing day.

Where to Eat: A Taste of St. Louis
St. Louis has a unique culinary scene. For a day trip, focus on these quick, iconic, and delicious local specialties.
For Iconic Toasted Ravioli: The Hill
You cannot visit St. Louis without trying toasted ravioli (or “T-ravs”). These breaded, deep-fried ravioli are a local treasure. Head to the charming Italian neighborhood known as “The Hill.” We recommend Mama’s on The Hill ($$) for a classic sit-down experience or Gioia’s Deli ($) for a quicker, but equally delicious, version.
For St. Louis Style BBQ: Pappy’s Smokehouse
While Kansas City gets more BBQ buzz, St. Louis holds its own with a distinct style focusing on ribs that are grilled and then slathered in a sweet and tangy tomato-based sauce. For some of the best, visit Pappy’s Smokehouse ($$) or Sugarfire Smoke House ($$). Be prepared for a line—it’s that good.
For a Sweet Treat: Gooey Butter Cake
This is exactly what it sounds like: a flat, dense cake with a buttery, gooey topping that is utterly addictive. It’s the perfect snack for the ride home. Pick some up from a local spot like Gooey Louie ($) or Park Avenue Coffee ($).
Planning Your 2025 Visit: Practical Details
Parking in St. Louis
Downtown parking garages near the Arch can run from $15-$30 for the day. We highly recommend using an app like SpotHero or ParkWhiz to find and pre-book a spot, saving you time and money. Parking near Forest Park is generally easier and cheaper, with a dedicated paid lot (~$15) and free street parking available if you’re lucky.
Safety Tips
Like any major city, situational awareness is key. Stick to well-populated tourist areas like Downtown, the Central West End, and Forest Park, especially during the day. Do not leave valuables visible in your car. After dark, it’s best to drive rather than walk long distances between areas.
Accessibility
St. Louis is generally very accessible. The Gateway Arch, St. Louis Zoo, and Missouri Botanical Garden are all ADA compliant with accessible paths and facilities. However, the City Museum, with its many tight spaces and climbing structures, is largely not accessible for those with mobility challenges.
What to Pack for Your Day Trip
Packing smart is essential for a long day on the road and on your feet. Here’s a quick checklist:
- Comfortable walking shoes (this is non-negotiable!)
- A portable phone charger or power bank
- A refillable water bottle to stay hydrated
- Snacks and drinks for the car
- A light jacket or sweatshirt, as building interiors can be cool
- Your camera or smartphone for photos
- Sunglasses and sunscreen
