Quick AnswerThe best family things to do in St. Louis are anchored by four experiences that kids genuinely remember: the free Saint Louis Zoo in Forest Park, City Museum's multi-floor climbing-and-cave labyrinth downtown, the Magic House children's museum in Kirkwood, and Grant's Farm's free wildlife tram and animal-feeding areas. St. Louis is unusually strong for families because most of its flagship attractions are free or low-cost admission. This guide covers what each place is actually like from a kid's perspective, organized by age range and energy level.
St. Louis has the rare combination of big-city institutions and an approachable, manageable scale that makes it genuinely great for families on a weekend trip. You can walk out of a world-class science museum, grab lunch on The Hill, and still make it back to Forest Park for an afternoon stroll — all without fighting impossible traffic or blowing your budget on admission fees.
This guide is framed around the weekend-trip mindset: activities you can anchor a Saturday or Sunday around, places where you'll spend two to four hours without running out of things to see, and a mix of free and paid options that cover toddlers through teenagers.
Our Top Family Things to Do in St. Louis
1. Saint Louis Zoo — Your Forest Park Anchor
The Saint Louis Zoo is the correct starting point for almost any family weekend in St. Louis, and the fact that admission is free makes it a no-brainer. Over 14,000 animals across a beautifully maintained campus in the center of Forest Park — from the dramatic River's Edge hippo area to the beloved penguin and puffin coast. The children's zoo section includes hands-on animal encounters that turn a passive zoo visit into something genuinely participatory.
Plan for three to four hours minimum and arrive before 10am on summer weekends to beat the crowds. The zoo sits at the eastern edge of Forest Park, which means you can walk directly to the Art Museum hill or the paddleboat lagoon after you finish. A zoo morning followed by a Forest Park afternoon is a genuinely excellent St. Louis day.
2. City Museum — The Most Original Thing in St. Louis
City Museum in downtown is simultaneously a climbing structure, an art installation, a cave system, and a rooftop playground with school buses mounted on it. It defies description and rewards just showing up. Kids vanish into crawl tunnels and resurface on different floors. The Enchanted Caves section appeals to younger kids; the outdoor structures and the 10-story slide draw teenagers and adults who came in skeptical.
Budget at least three to four hours and dress in clothes you can scuff. City Museum is paid admission and worth every dollar — it's the kind of place children request to return to on every subsequent St. Louis visit.
3. Magic House — Best Children's Museum in the Region
The Magic House in Kirkwood spreads across a beautifully restored Victorian home connected to modern exhibit wings covering over 100 interactive exhibits — sensory play for toddlers through engineering and physics challenges for middle-schoolers. The "Just for Me" wing for children under 7 is a full dedicated space, not a cordoned-off corner. Older kids gravitate toward the electricity lab and the balance and motion exhibits.
Budget two to three hours. Admission is paid, but a family membership pays for itself in two visits — worth it if you're in the region long-term.
4. Missouri Botanical Garden — Worth Every Season
The Missouri Botanical Garden in Tower Grove is one of the oldest botanical gardens in the country, and its programming calendar makes it worth visiting in any season — spring tulips, summer Japanese Garden, fall Scarecrows, December's wildly popular Garden Glow light installation. The Children's Garden is a dedicated outdoor play space with water features, climbing elements, and interactive educational structures designed specifically for kids under 12.
Admission is paid, with meaningful discounts for St. Louis City and County residents. Combine the Garden with a walk through Tower Grove Park directly to the north for a complete afternoon.
5. Saint Louis Science Center — Free and Genuinely Impressive
The Saint Louis Science Center in Forest Park is free for general admission and consistently underestimated. Four floors of hands-on exhibits, a planetarium, an IMAX theater, and a life-size dinosaur fossil hall hold up against the country's best science museums. The geodesic dome planetarium is a Forest Park landmark; the Discovery Room across Oakland Avenue effectively doubles the accessible floor space.
Planetarium and IMAX shows cost extra but are worth budgeting for. Plan for two to three hours in the main building, more if you do the full campus.
6. Grant's Farm — A St. Louis Original
Grant's Farm in Affton is one of those uniquely St. Louis experiences that doesn't translate easily to description. A wildlife preserve on land once owned by Ulysses S. Grant, it combines a tram ride through deer and bison fields with hands-on animal feeding areas where kids interact with goats, camels, and other animals at close range. Admission to the park is free — you pay for parking and optional extras.
Arrive before 10am on summer weekends, as it fills quickly. Grant's Farm occupies a middle ground between zoo and petting farm that feels distinctly St. Louis in character — more intimate than the Saint Louis Zoo, with a sense of history behind it.
7. Powell Hall — Family Concert Experiences
Powell Hall in Grand Center is home to the Saint Louis Symphony Orchestra, one of the finest regional orchestras in the country. Their Discovery Concerts series for families with children ages 5–12 features shorter programs, pre-concert activities, and narrated introductions that make classical music genuinely approachable. The hall itself — a beautifully restored 1925 theater — impresses kids and adults equally.
Check the SLSO calendar early; Discovery Concerts sell out. The Symphony's outdoor concerts in Forest Park during summer are a low-commitment introduction for families new to the experience.
8. Forest Park — The City's Living Room
Forest Park is 1,300 acres of public green space in the center of St. Louis, and while it's easy to treat it as backdrop, the park itself is a family destination. Paddle boats on Post-Dispatch Lake rent seasonally. The Art Hill sled run after winter snowfall is a generational St. Louis ritual. The recently updated playground infrastructure and wide cycling and running paths make it a year-round activity hub.
Forest Park is free, close to everything, and functions as the connective tissue of a St. Louis family weekend — the place you pass through on the way to somewhere else and often end up staying longer than planned.
9. Citygarden — Downtown Sculpture Park
Citygarden is a six-block urban sculpture park running along Chestnut Street between 8th and 10th Streets downtown, with 25 major sculptures from artists including Kiki Smith and Tom Otterness — all in a free, open public space. The Tom Otterness bronzes are playful and designed to be touched and climbed on. The integrated splash pad and shallow pools become a magnet for children on warm days.
Bring a change of clothes for younger kids in summer. Citygarden sits walking distance from the Arch grounds, making it an easy add-on to a riverfront visit.
10. World Aquarium at Union Station — Rainy-Day Anchor
The World Aquarium at St. Louis Union Station — inside the historic 1894 train station complex — features marine and freshwater exhibits, stingray touch tanks, and an introductory shark tunnel. The Union Station complex surrounds it with a Ferris wheel, mini golf, and laser tag, turning an aquarium visit into a full afternoon. The Great Hall itself is one of the most architecturally striking spaces in the city.
Admission is paid with bundled packages available. It's not the Saint Louis Zoo in scale, but as a contained indoor option for mixed-age groups, it covers the gap.
