Top Things to Do in St. Louis with Kids (The Must-Do List)

When compiling a list of things to do in st. louis with kids, a few iconic attractions simply cannot be ignored. These are the heavy hitters that define a family trip to the Gateway City.

City Museum

Do not let the word "museum" fool you. The City Museum is an industrial-chic, 10-story 'city within a city' built entirely from repurposed architectural and industrial materials. It is a massive, surreal playground of caves, slides, airplanes suspended in the air, and an iconic rooftop Ferris wheel.

Practical Details: General admission runs about $20 USD per person, with rooftop access costing a few dollars extra. Hours fluctuate by season, but they are generally open from 10:00 AM to 6:00 PM (open later on weekends). Parent Tip: Leave the stroller in the car. This place is all about squeezing through tight tunnels and climbing rebar structures. Dress your kids in bright, easily identifiable colors, require closed-toe shoes, and strongly consider bringing knee pads for yourself if you plan on chasing toddlers through the cave system.

Saint Louis Zoo

Consistently ranked as one of the best zoos in the United States, the Saint Louis Zoo is a 90-acre park that offers a rare world-class attraction with completely free admission. You can spend an entire day here marveling at the penguin and puffin coast, watching the elephants, and walking through the incredible primate canopy trails.

Practical Details: While entry is free, parking in the official lots costs about $20 USD. The zoo opens at 8:00 AM or 9:00 AM depending on the season. Parent Tip: Free entry is amazing, but individual costs for the Zooline Railroad, the Carousel, and the Stingrays at Caribbean Cove add up fast. Budget for these extras in advance. The zoo is heavily paved and very stroller-friendly, with plenty of shaded areas to rest.

Gateway Arch National Park

You cannot visit St. Louis without experiencing the Gateway Arch National Park. This iconic 630-foot stainless steel monument offers a unique tram ride to the top and a high-quality, recently renovated museum at the base that details the history of westward expansion.

Practical Details: Tram tickets run between $15 and $19 USD for adults, and $11 to $15 USD for kids (ages 3-15). The museum at the base is free and completely stroller accessible, but you must fold your stroller to take the tram to the top. The pods are very small (seating five people tightly), so prepare claustrophobic kids ahead of time.

The Magic House, St. Louis Children's Museum

Located in the suburb of Kirkwood, The Magic House, St. Louis Children's Museum is a massive 55,000-square-foot Victorian mansion transformed into an interactive wonderland. From a three-story beanstalk climber to a kid-sized village where they can play mechanic or grocery clerk, this museum is a paradise for younger kids.

Practical Details: Admission is around $14 USD per person. It is highly accessible for strollers, though parking can fill up quickly on weekend mornings. Parent Tip: Avoid scheduling the City Museum and The Magic House on the same day. Both are high-sensory, physically demanding 'marathon' attractions. Doing both in one day is a one-way ticket to sensory overload and exhaustion for everyone involved.

Best Outdoor Things to Do in St. Louis with Kids

St. Louis boasts some of the most beautiful and expansive green spaces in the country. When the weather is cooperating, you will want to spend as much time outside as possible.

Missouri Botanical Garden & Children's Garden

The Missouri Botanical Garden is a stunning oasis in the city, but families will want to make a beeline for the Missouri Botanical Garden (Doris I. Schnuck Children's Garden). This is a fenced-in, high-security wonderland within the larger botanical garden featuring a splash pad, treehouses, a limestone cave, and a steamboat.

Practical Details: General garden admission is about $14 USD for adults (kids 12 and under are free), but entry to the Children's Garden requires an additional $5 USD ticket for kids ages 3-12. Bring water shoes and a towel, as the splash pad is irresistible on a hot Missouri afternoon.

Sophia M. Sachs Butterfly House

Located in Faust Park, the Sophia M. Sachs Butterfly House is a lush, 8,000-square-foot tropical conservatory where over 1,500 butterflies fly freely, often landing directly on visitors.

Practical Details: Admission is around $8 USD for adults and $5 USD for children. The conservatory is kept very warm and humid to keep the butterflies happy, so dress in layers. It is incredibly peaceful and a great low-energy activity for a quiet morning.

Turtle Playground

If you are spending the day in Forest Park, make a quick stop at Turtle Playground. This is a whimsical, open-air art installation featuring giant concrete turtles, a long snake, and oversized turtle eggs.

Practical Details: It is completely free and accessible 24/7. It is the perfect 30-minute stop to let kids climb and burn off energy before getting into the car for a long drive or a nap.

Grant's Farm

Once the home of Ulysses S. Grant, Grant's Farm is now a sprawling 281-acre wildlife preserve and historical site operated by the Busch family. Families take a tram through free-roaming herds of deer, bison, and zebra before arriving at the main tier where you can feed baby goats and see the famous Clydesdale horses.

Practical Details: Admission to the farm is free, but parking is around $16 USD. You will also want to bring small bills to purchase milk bottles for the baby goats—a highlight for almost every child who visits.

Historical Thrills and Iconic St. Louis Eats

Incorporating history and local food into your itinerary is easy in a city with such deep cultural roots.

Cahokia Mounds State Historic Site

Just across the river in Illinois, you will find the Cahokia Mounds State Historic Site. This massive UNESCO World Heritage site features the remains of the largest pre-Columbian city in North America. The highlight is Cahokia Mounds - Monks Mound, a massive 100-foot-high ancient earthwork.

Practical Details: The grounds are free to explore from dawn to dusk. Climbing the hundreds of wooden stairs to the top of Monks Mound offers an incredible view of the St. Louis skyline and is guaranteed to exhaust even the most energetic school-aged kids.

Fitz's American Grill & Bottling Works

For lunch, head to the Delmar Loop to visit Fitz's American Grill & Bottling Works. This is a high-energy root beer factory and restaurant where families can watch a vintage 1940s bottling line churn out fresh sodas right from their tables.

Practical Details: Meals are moderately priced (around $15 USD for a burger). The portions are huge, and the root beer floats are legendary.

Ted Drewes Frozen Custard

No St. Louis trip is complete without a stop at Ted Drewes Frozen Custard. This legendary landmark is where families flock for 'concretes'—custard so thick it is served upside down without spilling.

Practical Details: Concretes cost between $4 and $7 USD depending on size and mix-ins. There is no indoor seating, so you will eat standing in the parking lot or leaning against your car, which is part of the charm.

Evening Entertainment: Shows and Splurges

If your kids are old enough to stay up past sunset, St. Louis has some incredible evening entertainment options.

The Muny

Located in Forest Park, The Muny is America's oldest and largest outdoor musical theater. They produce high-quality Broadway shows on a massive scale under the stars.

Practical Details: The season runs during the summer. While reserved seats can be pricey, The Muny famously offers nearly 1,500 free seats in the very back rows on a first-come, first-served basis. Pack a picnic, arrive early, and enjoy a magical night of theater.

The Fabulous Fox Theatre

For tweens and teens, catching a touring Broadway show at The Fabulous Fox Theatre is an unforgettable splurge. This breathtaking 1929 'Siamese-Byzantine' movie palace feels like a trip to a gilded fantasy world, complete with velvet curtains, massive chandeliers, and intricate architectural details.

Age-by-Age Guide to Things to Do in St. Louis with Kids

Tailoring your itinerary to your children's developmental stages makes all the difference. Here is how to break down the best things to do in st. louis with kids by age group.

Toddlers (Ages 2-3)

Toddlers thrive in contained environments where they can safely touch and explore.

• The Magic House: The dedicated toddler areas are soft, safe, and engaging.
• Children’s Garden at Missouri Botanical Garden: The splash pad and gentle musical instruments are perfect.
• Sophia M. Sachs Butterfly House: The warm environment and gentle butterflies are mesmerizing for two-year-olds.

Preschoolers (Ages 3-5)

Preschoolers have endless energy and blossoming imaginations.

• Saint Louis Zoo: They are the perfect age for the carousel and feeding the stingrays.
• Grant’s Farm: Feeding the baby goats with milk bottles will be the highlight of their trip.
• Turtle Playground: Safe climbing on giant concrete animals is exactly what this age group needs.

School-Age (Ages 6-10)

This age group wants physical challenges and a sense of independence.

• City Museum: They are old enough to navigate the slides and caves without you holding their hand the entire time.
• Gateway Arch: The history of westward expansion starts to click, and the tram ride feels like a real adventure.
• Monks Mound at Cahokia: They will love the physical challenge of racing to the top of the 100-foot earthwork.

Tweens and Teens (Ages 11-14)

Older kids want unique aesthetics, great food, and experiences they can share with friends back home.

• City Museum (Rooftop): The rooftop Ferris wheel and school bus hanging off the edge of the building offer incredible photo ops.
• Fitz’s Bottling Works: Watching the factory line while drinking massive floats appeals to their growing appetites.
• The Fabulous Fox Theatre: Getting dressed up for an evening show makes them feel grown-up and respected.

What to Skip: Overhyped St. Louis Attractions for Families

Not every popular attraction is a win for families. Here are a few places you can confidently cross off your list to save time, money, and sanity.

St. Louis Union Station - Aquarium + Wheel Combo Tickets

Do not fall for the St. Louis Union Station - Aquarium + Wheel Combo Tickets. The combo ticket is a classic 'value trap' that encourages families to over-schedule in a high-density tourist area. The aquarium is quite small and extremely crowded, and trying to force the ropes course, the Ferris wheel, and the aquarium into one day will leave everyone cranky and your wallet significantly lighter.

Cathedral Basilica of Saint Louis

While the 41 million mosaic tiles are undeniably a world-class sight, the Cathedral Basilica of Saint Louis is an environment of strict, enforced silence. Ushers will quickly shush families, making it a highly stressful environment if you have a babbling toddler or an energetic preschooler. Save this for an adults-only trip.

Anheuser-Busch Brewery Tour

Many guides recommend the Anheuser-Busch Brewery Tour because it is free and features the famous Clydesdales. However, the standard 75-minute tour is a trudge for kids. It is heavily focused on corporate history, brewing vats, and long walks through hot industrial buildings. If you want to see the horses, go to Grant's Farm instead.

Ted Drewes Frozen Custard (Chippewa St at 7:00 PM)

You absolutely should eat at Ted Drewes, but you must avoid Ted Drewes Frozen Custard (Chippewa St at 7:00 PM). Visiting during the post-dinner peak means braving 45-minute lines on a hot asphalt parking lot alongside hundreds of other people. Go at 2:00 PM for a mid-afternoon treat instead.

The Loop Trolley

The Delmar Loop is a fun neighborhood, but skip The Loop Trolley. The trolley is notoriously unreliable, frequently failing to appear for scheduled stops and operating on a confusing schedule. Your kids will get frustrated waiting in the sun—just walk the loop instead.

Lemp Mansion (Evening Ghost Tour)

The Lemp Mansion (Evening Ghost Tour) is a popular local activity, but these tours are focused on a heavy, tragic family history—including multiple real-life suicides. It is entirely inappropriate and frightening for children and young teens.

Pro Tips from Parents for Your St. Louis Trip

To make your trip as smooth as possible, keep these hard-earned parent tips in mind:

• Understand the Scale of Forest Park: Forest Park is 1,300 acres—significantly larger than New York's Central Park. Walking between the Zoo and the Science Center with kids is exhausting and will eat up your whole day. Use the seasonal Forest Park Explorer shuttle bus or drive between the specific lots.
• Beat the Midwest Humidity: St. Louis summer humidity is intense and oppressive. Plan your outdoor activities like the Gateway Arch grounds or the Zoo for the very first thing in the morning, then retreat to air-conditioned havens like the City Museum or Magic House after lunch.
• Eat on 'The Hill': Skip the generic chicken nuggets and take the kids to 'The Hill' neighborhood for toasted ravioli, a St. Louis original. It is basically deep-fried pasta filled with meat and dipped in marinara—a guaranteed hit with picky eaters.
• Navigate the Delmar Loop Smartly: Visit the Delmar Loop during the day to see the St. Louis Walk of Fame and grab a root beer at Fitz's. After 8:00 PM, the atmosphere shifts and it becomes much less family-friendly.
• Avoid Downtown BBQ at Lunch: While St. Louis BBQ is world-class, the downtown locations see massive lines of office workers from 11:30 AM to 1:00 PM. With hungry kids, plan to eat your BBQ at 11:00 AM sharp or wait until dinner.
• Be Careful with Transit: While the light rail (MetroLink) is convenient for getting to Busch Stadium, the trains become incredibly packed and rowdy immediately following a Cardinals baseball game. If you have strollers or very young kids, consider walking a few extra blocks or utilizing a rideshare instead.

St. Louis is a city that welcomes families with open arms, offering a remarkable blend of history, outdoor exploration, and imaginative play.
