Family Fun Things to Do in Houston: Seven Picks for Kids

1. Hermann Park: best for all ages and a free start

Hermann Park is the easiest free start, and you can circle Hermann Park with kids in one morning. The park charges no admission and is open daily from 6 a.m. to 11 p.m., according to the Hermann Park Conservancy. The miniature train and the carousel run from 10 a.m. to 6 p.m. Pedal boats run from 10 a.m. to 5 p.m.

For toddlers, the Commons Play Garden and Water Play is open from 9 a.m. to 9 p.m. daily. Hermann Park, Children's Museum Houston and Discovery Green are the three picks here that suit the youngest children best. The park page lists no ticket prices for the train, carousel or boats. Call 713-524-5876 to ask.

Parking is free in several lots, including Lot A by the Sam Houston Monument. You can also ride the METRORail Red Line to the Memorial Hermann Hospital/Houston Zoo stop, then walk about 10 minutes. The fare is $1.25, as METRO states. Read getting around Houston for the rest of the system.

The Houston Zoo sits inside the park. Its first-Tuesday free days fall on 3 November and 1 December 2026, and you must reserve online.

Pro Tip Do the train and carousel at 10 a.m., before lunch. Both close at 6 p.m., and the pedal boats close at 5 p.m.

2. Space Center Houston: best for school-age kids

Space Center Houston is the pick for kids who like rockets and real NASA buildings. Online tickets for adults aged 12 and older run from $29.95 to $39.95, depending on the date. Kids aged 4 to 11 pay $24.95 to $34.95, and children aged 3 and under are free, according to Space Center Houston.

Entry is timed. You can ask for a refund or a new time at least 48 hours before your ticket time. Parking is $10 plus a service fee.

The page gives no total visit length. The open-air tram tour lasts 60 to 90 minutes and involves some walking, so plan a half day or more. No official page gives a full visit length, so use these as a guide: Hermann Park fits in one morning, the aquarium an afternoon, the dolphin cruise takes 45 minutes and the Space Center a half day or more. For comparison, the dolphin cruise lasts 45 minutes and Hermann Park fits in one morning. The Astronaut Training Facility tour and the Rocket Park tour are free with admission, and both run first come, first served. The NASA VIP tour is currently unavailable.

The Space Center's page gives no distance from downtown and no public transit route. Plan on a car or a ride. For tickets and tours, read the Space Center Houston page.

3. Children's Museum Houston: best for younger kids

Children's Museum Houston is built for younger children, and the museum lists an Early Learners program for ages 0 to 5. It does not state an overall age range. The address is 1500 Binz St.

Check the closures before you buy. On 28 October 2026 the museum's home page marked 21 exhibits as temporarily closed, including PowerPlay, Kidtropolis, FlowWorks and Invention Convention. Viva Village was not marked closed. The Children's Museum Houston entry ticket is on GetYourGuide from €21 per person, rated 4.6 from 54 reviews, run by Children's Museum Houston, with free cancellation. The listing excludes the SECRET Spy Game exhibit, food and drinks.

Prices and ratings as shown on GetYourGuide on 27 October 2026.

The museum's free family night is on Thursdays from 5 to 8 p.m. It needs a reservation, and each group needs at least one child. Tickets drop 48 hours before each Thursday. The event page notes that many exhibits are closed, so the free night is a lighter visit.

4. Houston Museum of Natural Science: best for curious school-age kids

The Houston Museum of Natural Science is at 5555 Hermann Park Drive, next to the park. General admission is $25 for ages 12 and up and $16 for ages 3 to 11. Children under 2 are free, as the museum's visit page lists. For a family of two adults and two kids aged 5 and 8, that is $82 at the door, or nothing on a Tuesday evening. Hours are 9 a.m. to 5 p.m. Monday to Thursday and 9 a.m. to 6 p.m. Friday to Sunday.

Admission is free on Tuesdays from 5 to 8 p.m. The page also says two halls, Gems and Minerals and Entomology, are currently closed. Garage parking is $30, so many families park free in the Hermann Park lots and walk.

The Butterfly Center ticket is on GetYourGuide from €13 per person, rated 4.7 from 103 reviews, run by The Houston Museum of Natural Science, with free cancellation. The ticket buys entry to the Cockrell Butterfly Center only, and excludes other exhibits. That is cheaper than the museum's own $25 or $16 general admission, but it covers far less. The listing gives no meeting point, duration or group size. Its page describes a three-story glass building with more than 1,500 butterflies.

For general admission, book on the museum's own site or read the Houston Museum of Natural Science tickets page.

5. Galveston dolphin cruise: best for a beach day

Galveston is a good pick when the kids need space to run. The island is 50 miles south of Houston, according to the City of Galveston. That page gives no drive time. Plan a full day, and see Galveston day trips from Houston for more stops.

A Galveston dolphin tour is the easiest water activity. The Galveston dolphin cruise is on GetYourGuide from €29 per person, rated 4.7 from 286 reviews, run by Baywatch Dolphin Tours. The trip lasts 45 minutes, and the group size is up to 52. The meeting point is 2100 Harborside Dr, Galveston. The listing offers free cancellation, and the cruise starts at the meeting point, so you drive yourself to the dock. It excludes hotel pickup and drop-off, food, drinks and tips. It is the only paid stop here with a published trip length, so it is easy to fit around a beach day.

The boat has restrooms on board. Bring your own sun protection and water. The listing does not state an age limit, so ask the operator if you travel with a baby.

6. Discovery Green: best free stop downtown

Discovery Green is a 12-acre downtown park at 1500 McKinney St. It is open daily from 6 a.m. to 11 p.m., and the park's visit page says "Admission is always free". It has a water park for kids, and family changing rooms for the fountains open from 9 a.m. to 9 p.m. The information center is open from 9 a.m. to 6 p.m.

The park lists more than 600 events a year, and most are free. Check its Families and Children category before you go. A winter ice rink opens in the lake basin each year. The 2026 to 2027 season dates were not posted when this page was read.

7. Downtown Aquarium: best for a rainy or hot afternoon

The Downtown Aquarium is an indoor and ride-filled stop at 410 Bagby St. The All Day Adventure Pass is $25.99 for adults and $24.99 for children under 42 inches. Children aged 2 and under are free with an adult pass. The Aquarium Adventure exhibit alone is $16.99 for adults and $14.99 for children under 42 inches, as the aquarium's ticket page lists. Single rides cost $5.25 to $7.25.

Some rides have height or weight limits, and the aquarium posts them at each ride. Strollers must stay outside attractions. The page gives no typical visit length, so plan an afternoon. On cost, a family of four pays about $102 for the All Day Adventure Pass, or about €63 per person for the city tour bundle with entry. For a family of four, the All Day Adventure Pass is about $102 with two adults and two children under 42 inches. The other stops give little on length: the Space Center suggests a half day, the dolphin cruise takes 45 minutes, and the two museums publish no visit length. Outside food and drink are not allowed. Parking behind the building costs $15 for self-parking and $18 for valet.

If you also want a city view, the Houston city tour with a Downtown Aquarium ticket is on GetYourGuide from €63 per person, rated 4.6 from 19 reviews, run by Houston City Tours LLC. It pairs an open-air double-decker bus tour with aquarium admission. The meeting point is 1302 Dallas St, Houston, TX 77002. The listing is not suitable for wheelchair users, people with mobility impairments or people with heart problems. It excludes food, drinks, tips and transport to the aquarium, and it offers free cancellation.

Prices and ratings as shown on GetYourGuide on 27 October 2026.

For the other ways to book, read about downtown aquarium-houston tickets before you choose.

Key Takeaway Hermann Park, Discovery Green and the Tuesday-evening museum hours are free, so a Houston family day can cost nothing but parking.

How to choose family fun things to do in Houston

Pick by your youngest child first, then by the weather. Young children do best in Hermann Park, the Children's Museum and Discovery Green. School-age kids get the most from the Space Center and the Museum of Natural Science. A heat or rain day calls for an indoor stop, such as a museum or the aquarium.

Teens cost more. The Space Center and the Museum of Natural Science list adult tickets from age 12, and the aquarium prices by height, so a tall teen pays the adult rate there too. No official page says what teenagers enjoy most, so ask your teen and match the stop to the interest: rockets at the Space Center, the halls at the Museum of Natural Science, or the rides at the aquarium. For an older group, Meow Wolf Houston tickets are another option, and the venue says weekday evenings, Friday evenings and weekends often sell out.

The Best Travel Destinations' count of GetYourGuide listings for Houston in October 2026 found 13 entry tickets under €30 per person, out of 93 listings. Those are the self-paced choice for a family, and most are museums.

Is a tour worth it? For most of these picks, no. All four GetYourGuide listings show free cancellation and a named operator, with ratings of 4.6 to 4.7, and the prices are GetYourGuide prices, not the venues' own. Hermann Park and Discovery Green need no ticket, and the museums and the aquarium sell their own. A GetYourGuide listing makes sense when you want free cancellation or a bundle, like the aquarium with a city tour. The dolphin cruise is a booking either way, so a listing is a fair way to get it.

Skip the Children's Museum ticket if the exhibits your kids want are on the closed list. The museum's page is the one to check on the day.

Kids remember the open space and the one big thing, not the length of the list.
