Things for Kids to Do in St. Louis | Free Fun First

St. Louis works for families because the zoo, science center, Forest Park, and several museums are free or low-cost.

A family weekend built around things for kids to do in St. Louis works best when you start with the free anchors, then add one paid splurge. The city is unusually strong for families because Forest Park alone covers animals, science, art, history, playgrounds, trails, and picnic space without turning every stop into a ticket purchase.

The smartest plan is simple: use the Saint Louis Zoo or Saint Louis Science Center as your low-cost base, save City Museum or The Magic House for the high-energy indoor block, then add Gateway Arch National Park if your kids are old enough for the tram pods and security line. For families who want timed activities, tours, riverboat rides, or attraction bundles, compare current family options after you know which area of town you are using:

Kid-Friendly Things To Do In St. Louis By Age

St. Louis family activities split cleanly by age: toddlers do best at The Magic House, elementary-age kids usually love the zoo and science center, and older kids tend to remember City Museum most. Mixed-age families should pick one controlled indoor stop and one open-air stop each day.

City Museum is the most distinctive choice, but it is not a quiet museum. The building is full of slides, tunnels, climbing spaces, art pieces, and roof access when weather allows. Daily tickets currently start at about $20 online, and children age 2 and under are free, with roof access and some extras handled separately.

The Magic House in Kirkwood is easier for younger kids because the exhibits are built around hands-on play rather than big physical climbing. Current all-day admission is $15 for adults and children age 1 and up, and children under 1 are free. Summer public hours generally run 9:30 a.m. to 5 p.m. Monday through Saturday and 10:30 a.m. to 5 p.m. Sunday, but special hours can shift around school breaks.

• Ages 2 to 5: The Magic House, Saint Louis Zoo, Missouri Botanical Garden Children’s Garden.
• Ages 6 to 10: Saint Louis Science Center, Gateway Arch museum, Grant’s Farm, Forest Park playgrounds.
• Ages 10 and up: City Museum, Gateway Arch tram, Union Station attractions, Cardinals game days.

Start With The Free Heavy Hitters

Saint Louis Zoo and Saint Louis Science Center are the easiest first picks because general entry is free and both can absorb several hours. Families who are watching costs can build a full day from Forest Park without paying admission at every stop.

The Saint Louis Zoo is always free for general admission, and its 2026 summer schedule lists 8 a.m. openings with closing times from 5 p.m. to 6 p.m. on most summer days. Paid extras include attractions such as the carousel, sea lion show, 4D theater, stingrays, and railroad, so you can keep the day free or add one small upgrade.

The Saint Louis Science Center also lists free entry, with paid parking, OMNIMAX shows, special attractions, and some ticketed programs. Sunday sensory-friendly time from 9:30 a.m. to 11:30 a.m. is a useful fit for kids who do better with reduced noise and gentler show settings.

Forest Park works well between museums because it gives kids a reset: walk, snack, playground, then another indoor stop. The park is home to the zoo, science center, Missouri History Museum, Saint Louis Art Museum, and The Muny, so families can switch plans fast when weather changes.

How Many Days Do Families Need In St. Louis?

Two full days is enough for the strongest kid-focused St. Louis trip, and three days lets you add a slower outdoor morning. One day can work if you stay near Forest Park or downtown and choose no more than three stops.

A one-day plan should pair the Saint Louis Zoo with the Saint Louis Science Center or choose Gateway Arch National Park plus City Museum. Do not try to combine City Museum, the zoo, the Arch tram, and Union Station in one day; each one has enough walking, waiting, or climbing to wear kids down.

A two-day family plan gives you better pacing:

1. Day one: Saint Louis Zoo in the morning, Forest Park picnic or playground, Saint Louis Science Center in the afternoon.
2. Day two: Gateway Arch National Park early, City Museum after lunch, Union Station for dinner and an evening attraction if kids still have energy.

The official St. Louis tourism site groups family attractions, free experiences, and kid-focused ideas in its St. Louis kids activity guide, which is a helpful planning cross-check when you need current event ideas around your travel dates.

Paid Attractions That Are Actually Easy With Kids

Gateway Arch National Park, City Museum, The Magic House, and Union Station are the paid or partly paid stops most families should weigh first. Each one solves a different problem: landmark, movement, toddler play, or weather backup.

The Gateway Arch tram is memorable, but families should plan around the logistics. Current tram pricing starts at $15 for adults, $11 for children ages 3 to 15, and free for infants age 2 and under. The tram experience usually takes 45 to 60 minutes, and the security line can add time on busy days.

Grant’s Farm is a strong value when the weather is decent. General admission is free, with a required vehicle parking ticket that currently costs $18 online in advance or $27 at the farm. The animal areas, shows, and Clydesdales make it feel like a paid attraction even when you keep the add-ons modest.

Union Station is the easiest choice when a family needs indoor options in one place. The St. Louis Aquarium anchors the complex, and the Wheel, ropes course, mirror maze, carousel, mini golf, and food spots let you stretch the visit without driving across town. Children 12 and under must be with an adult at Union Station attractions, and guests 16 and younger need a supervising adult age 21 or older after 3 p.m.

Where To Stay For Easy Family Days

Families should stay near Forest Park, Downtown, or Union Station depending on the trip’s anchor attraction. Forest Park is better for free museums and the zoo, while Downtown works better for Gateway Arch National Park, City Museum, and riverfront plans.

Forest Park keeps driving low if your family wants the zoo, science center, history museum, playgrounds, and art museum. Downtown keeps the Arch, City Museum, and Union Station within a shorter ride, which helps when kids need a midday break.

Compare family-friendly hotels by map before choosing, because a slightly cheaper room can lose value if it adds parking stress or long rides between naps and dinner:

Use Weather To Pick The Right Day

St. Louis weather should shape the order of your family itinerary, not just what you pack. Hot summer afternoons and stormy days are better for the science center, aquarium, Magic House, or City Museum than for long outdoor blocks.

Outdoor-first mornings work well for the zoo, Grant’s Farm, the Missouri Botanical Garden, and Forest Park trails. Afternoon indoor blocks work better for exhibits, shows, and timed tickets. That rhythm cuts down on heat breaks and gives kids a clear reset before dinner.

Missouri Botanical Garden is strongest from spring through fall, especially when the Doris I. Schnuck Children’s Garden is open April through October. The Children’s Garden currently charges $5 for nonmember children ages 3 to 12, while adults and kids age 13 and up enter that area free after general garden admission rules are handled.

Parent planning tip: Put the highest-energy stop first. City Museum after a full zoo morning can be too much for younger kids, but City Museum first and a calm dinner after often works.

Which St. Louis Kids Plan Fits Your Family?

The right St. Louis family plan depends on energy level more than age alone. Pick one anchor, one backup, and one food-friendly area per day so the trip stays flexible.

• Free-first day: Saint Louis Zoo, Forest Park lunch, Saint Louis Science Center.
• Big-energy day: City Museum, a hotel rest, then Union Station for dinner and one attraction.
• Landmark day: Gateway Arch tram, Arch museum, riverfront walk, then a short indoor stop.
• Younger-kids day: The Magic House, Kirkwood lunch, Missouri Botanical Garden Children’s Garden in season.
• Animal day: Saint Louis Zoo early, Grant’s Farm later, with no extra museum squeezed in.

For most families, the strongest St. Louis trip is not the longest list. The better move is a zoo or science-center base, one paid experience your kids will talk about later, and a hotel location that makes breaks easy.
