Kids & Families mission for small astronauts

The zoo began with a single bison named Earl, sent to Houston from a government herd in Oklahoma, and officially opened in 1922. Today it covers 55 acres with thousands of animals and draws around 2 million visitors a year. Start with the Galápagos Islands, the capstone of the zoo's centennial campaign, which opened in 2023: California sea lions swim over a 40-foot acrylic tunnel, Humboldt penguins waddle in a chilled habitat, and giant tortoises graze outside. From there, South America's Pantanal (2020) brings jaguars and giant river otters, the African Forest has gorillas and chimpanzees, and the McNair Asian Elephant habitat has pools where the herd swims. Texas Wetlands shows off bald eagles, alligators and whooping cranes. Tickets are sold online only, so book before you leave the house.

You'll spot the building from the street: architects Robert Venturi and Denise Scott Brown designed the 1992 building to look like a playful take on a grand civic museum. A 2009 expansion doubled it to 83,000 square feet, and with its community programs it reaches more than a million children and families a year. The star is Kidtropolis USA, a kid-sized city where children take on grown-up jobs and run the town. FlowWorks is the splash zone, so pack a change of shirt. Invention Convention and PowerPlay keep older kids busy building and climbing, while Tot*Spot gives babies and toddlers their own safe corner. Seasonal festivals fill the calendar. Plan on a full morning, and expect younger kids to be wiped out by lunchtime.

Radio Tave opened on October 31, 2024 as Meow Wolf's fifth permanent exhibition and its second in Texas, set inside a restored early 20th century industrial complex in the Fifth Ward. More than 100 artists worked on it, roughly half from Texas. The premise: ETNL, a scrappy community radio station, has picked up a strange signal and cracked open a portal. You wander through rooms that twist from a small-town station into glowing, sound-soaked other worlds, and the fun for kids is that almost everything is touchable. Push buttons, open drawers, crawl through gaps and see what happens. There's a story to piece together if older kids want to play detective, and an in-universe bar and restaurant, Cowboix Hevvven, for when you need a break. Most families spend two to three hours inside, and it works just as well on a sweltering August afternoon as on a rainy Saturday.

Hermann Park has run a miniature railroad since 1957, and today's train loops about 1.8 miles on two-foot-gauge track, rolling past the zoo, under the trees and along McGovern Lake. The ride takes 20 to 25 minutes from Kinder Station at Lake Plaza, with stops at MD Anderson, Mullenweg and Bob Weekly stations, and a day pass lets you hop off and back on as often as you like. Since summer 2024 the trains have run on electric power instead of gasoline, so the ride is quieter than it used to be. Around the corner from the Sunday Press café at Lake Plaza, the boathouse rents pedal boats for a lap around the lake, with turtles and ducks for company. The Lott Family Carousel rounds out the trio. Pair all three with a morning at the zoo and you've built a full Hermann Park day.

The Health Museum started in 1969 as a medical science corner of the Houston Museum of Natural Science, moved into its own building in 1996, and took its short name in 2006. Its Amazing Body Gallery is a larger-than-life walking tour of the human body with about 30 interactive kiosks. Kids can stand inside a 10-foot walk-through brain, peer out of a walk-in eyeball, crawl through a 27.5-foot colon and watch a 12-foot heart that beats, and every so often stages a heart attack. For budding scientists, the DeBakey Cell Lab lets kids run real biology experiments in lab coats for a small add-on fee. The museum is compact, which makes it an easy two-hour stop, and it sits one block from the Children's Museum, so the two pair well on a single Museum District day.

Landry's opened the Downtown Aquarium in 2003 on a six-acre site built around two old city landmarks, Fire Station No. 1 and the Central Waterworks Building, and filled it with about 500,000 gallons of tanks. Inside the Aquarium Adventure exhibit, kids wander from a Texas bayou to a shipwreck, a sunken temple and a rainforest. The showstopper is the Maharaja's Temple, where the tigers live: Apollo, a Bengal rescued as a cub in San Antonio, and Zara and Kirana, Sumatran sisters born in 2023 who came to the aquarium through a conservation breeding program. Outside, the Shark Voyage train rolls through a tunnel surrounded by sharks, the Diving Bell Ferris Wheel lifts you above the grounds, and there's a carousel and small drop tower for younger riders. You can stroll the grounds for free and pay only for what you ride.

About 45 minutes southeast of downtown, where Clear Lake meets Galveston Bay, Kemah Boardwalk has been the family day trip since it opened in the late 1990s. Walking the boardwalk costs nothing, and watching boats slip through the channel is half the fun. When kids want rides, there are 13 on the All Day Ride Pass. The headliner is the Boardwalk Bullet, a wooden coaster that opened in 2007 and packs 3,236 feet of track, a 92-foot first drop and speeds of 51 mph onto a one-acre footprint right at the water's edge. Smaller kids head for the Double Decker Carousel, the C.P. Huntington Train and the Century Ferris Wheel. The Boardwalk Beast speedboat blasts out into the bay for an extra fee, and the Stingray Reef lets kids touch and feed rays. Stay for sunset over the water.

The Moody Foundation started Moody Gardens in 1986, and its glass pyramids are Galveston's most recognizable skyline. The Rainforest Pyramid, opened in 1993 and 10 stories tall, is warm, humid and alive: birds fly free overhead, a waterfall runs beside the path, and you'll find giant river otters, a Komodo dragon, an ocelot and a bat cave. The taller Aquarium Pyramid, opened in 1999 and renovated in 2017, holds 1.5 million gallons and moves through the Gulf of Mexico, the Caribbean, the North and South Pacific and the South Atlantic, with penguins, seals, sharks and a jellyfish gallery. The third pyramid, Discovery, is closed for now while it becomes the Galveston Children's Museum, due to open in November 2026. Add a 3D or 4D film to round out the day, and parking is always free.

This museum spent decades in Galveston until Hurricane Ike put seven to eight feet of water into its hangars in 2008. It rebuilt inland at Ellington Airport and reopened on September 16, 2017, two weeks late because Hurricane Harvey got in the way. The new home is about 130,000 square feet with its own ramp onto the airfield and about two dozen historic aircraft. For kids, head straight to the Flight Academy, 27 hands-on exhibits where they can design planes, learn why wings lift, sit in cockpit replicas of a Curtiss Jenny and two P-51 Mustangs, and steer hang-glider simulators. The Boeing Toddler Terminal gives the littlest pilots a place to play. Older kids at least 48 inches tall can strap into the MAX Flight simulator, which rolls a full 360 degrees. The Texas Aviation Hall of Fame honors names like Howard Hughes and astronaut Alan Bean.

Most visitors never see the waterway that made Houston a port city: the Houston Ship Channel. Port Houston has run free public cruises on it since the M/V Sam Houston made its first trip on July 30, 1958. The 95-foot boat carries up to 100 passengers, with air-conditioned lounge seating inside and deck space outside, and the round trip takes about 90 minutes. You leave from Sam Houston Landing and cruise past international cargo ships and the Turning Basin Terminal, while the crew answers questions about what's being loaded and where it's headed. Each passenger gets a free drink on board. For kids who love trucks, trains and anything enormous, watching a ship the length of a city block slide past is hard to beat, and the price is right: nothing at all.
