Things to Do in Houston with Kids: 20 Ideas Sorted by Age and Weather

Houston is quietly one of the best cities in the country for kids: a NASA visitor center, a top-ranked children's museum, a dinosaur hall that makes eight-year-olds go silent, and wild alligators an hour away. The hard part is the heat. This list flags what's indoors.

The big four (do these first)

Space Center Houston (ages 5+, indoor). Real rockets, the shuttle carrier you can walk through, and a tram into the actual Johnson Space Center. Book the earliest tram tour; the day only gets hotter and busier. Book tickets →.

Children's Museum Houston (ages 1 to 12, indoor). Regularly ranked the best in the US. The three-story climbing structure and the kid-run city keep them busy for four hours. Free Thursdays, 5–8pm.

Houston Museum of Natural Science (ages 4+, indoor). The dinosaur hall, the butterfly rainforest, and the planetarium. On the Houston CityPASS →, along with the zoo and the aquarium, which is the cheapest way to do several of these.

Houston Zoo (all ages, outdoor). Go at opening. The Galápagos exhibit and the sea lion show are the stars. Zoo Lights in winter is a must.

Doing the museums for less. Most of the big ones have a free window: the Children's Museum on Thursday evenings, Natural Science on Tuesday evenings (general admission only), and the MFAH's permanent collections all day Thursday. Two routes most parents never hear about: under-18s are free every day at Holocaust Museum Houston, and a Texas public library card gets under-18s into the MFAH free at weekends. We checked every one against the museum's own admission page: which Houston museums are free, and on which day.

Outdoor (October to April, or early mornings)

• Hermann Park: the miniature train, pedal boats, and the playground. Combine with the zoo.
• Kemah Boardwalk: rides and boat trips on the bay, 15 minutes from Space Center.
• Levy Park: the best under-8 playground in Houston, with a treehouse.
• Discovery Green: splash pad, playground, and a winter ice rink.
• Brazos Bend State Park: guaranteed alligator sightings from a safe trail, and an observatory on Saturday nights.
• Buffalo Bayou: the bat emergence at Waugh Bridge at dusk. Free, and a bigger hit than you'd expect.
• Armand Bayou Nature Center: pontoon boat tours and bison.
• Galveston: Moody Gardens (mostly indoor), Pleasure Pier, and the beach. Galveston tours and tickets →.

Rainy day or 100-degree day

• Downtown Aquarium: fish, white tigers, and a Ferris wheel. Touristy; kids don't care.
• The Galleria ice rink: skating in July.
• The Health Museum: walk-through organs, right in the Museum District.
• Topgolf, iFLY, and escape rooms: for tweens and teens.
• The Downtown Tunnels: a weekday adventure that's free.
• Houston Botanic Garden has shade and a children's garden; the winter Lightscape is spectacular.

By age

• Toddlers: Children's Museum (the Tot Spot), Levy Park, the zoo at opening, Hermann Park train.
• Ages 5 to 9: Space Center, Natural Science dinosaurs, Brazos Bend gators, Kemah rides.
• Tweens and teens: Space Center's tram tour, kayaking Buffalo Bayou, Topgolf, an Astros game at Daikin Park (roof closed, air-conditioned). Astros tickets →.

Where to stay with kids

The Museum District puts you walking distance from the zoo, the museums, and Hermann Park. Clear Lake/Kemah is the base for a NASA-and-boardwalk day. Family-friendly hotels near the Museum District →.
