San Antonio and the surrounding region give families a lot to work with: a world-class waterpark, underground caverns, river tubing, a safari drive-through, marine life, interactive museums, and enough free parks to fill a week without a theme park budget. The city itself has several strong options, and New Braunfels, 30 miles north on I-35, adds even more.
SeaWorld San Antonio is the biggest full-day family destination in the city. The park combines marine life presentations with roller coasters, water rides, and a dedicated splash area for younger kids. Aquatica, SeaWorld’s water park, runs alongside the main park and can be combined into a two-day visit.
Address: 10500 SeaWorld Dr, San Antonio, TX 78251. Seasonal. Check seaworld.com for current hours and pricing.
Natural Bridge Caverns, about 25 miles north of downtown San Antonio, is the largest cavern open to the public in Texas. The guided Discovery Tour takes families 180 feet underground through half a mile of formations. Above ground, the property has a ropes and zip rail course, a gem mining activity, and an outdoor maze.
Best suited for children 5 and up for the cave tours. Younger children can enjoy the above-ground activities. Book tickets in advance at naturalbridgecaverns.com — tours sell out on weekends.
Adjacent to the caverns, Natural Bridge Wildlife Ranch is a drive-through safari where animals including zebras, giraffes, ostriches, and many other species roam freely around your car. No walking required, which makes it practical for families with young children or toddlers. A self-paced experience that works at your own speed. Check naturalbridgewildliferanch.com for current hours and admission.
The DoSeum is San Antonio’s children’s museum and the best option in the city for families with younger kids. Interactive exhibits cover STEM, art, and the outdoor playground. The Spy Academy section is a consistent favorite for school-age children.
Address: 2800 Broadway St, San Antonio, TX 78209. Check thedoseum.org for hours and admission.
[H3] San Antonio River Walk (Go Rio Cruises)
The River Walk is walkable for older children and genuinely engaging, but the most practical family option is the Go Rio narrated boat cruise. The 35-minute tour runs from 10am to 10pm daily with boats departing every 15 to 20 minutes. Gives families a clear view of downtown and a way to move between areas without the walk.
Schlitterbahn is the anchor family destination in the region. The 70-acre waterpark is built on the Comal River, has four sections each with dedicated children’s areas, and has won more waterpark awards than any park in the world. Children 2 and under are free. Parking is free.
Open mid-April through mid-September, with daily operations from Memorial Day weekend. Buy tickets in advance at schlitterbahn.com. A full separate guide to planning your first Schlitterbahn visit is available on this blog.
Landa Park is a free 51-acre city park in New Braunfels, built around the headwaters of Comal Springs. A miniature train ride, paddleboat rentals, playgrounds, a spring-fed public pool, and shaded picnic areas along the river. A good low-key option for families with younger children who don’t need a full theme park experience.
At flow levels between 100 and 400 CFS, the Comal River is gentle enough for families with older children. A standard float takes about two hours. Several outfitters near downtown New Braunfels rent tubes and run shuttle service. Best for children who are comfortable in moving water. Not recommended for toddlers or very young children.
The two sit next to each other and are easily done in a single day. Start with the cave tour in the morning, eat lunch at the caverns, then do the wildlife safari drive in the afternoon.
Schlitterbahn, SeaWorld, and Natural Bridge Caverns all get busy on summer weekends. Tickets purchased in advance are cheaper and guarantee entry.
A vacation rental gives families the space, kitchen, and flexibility that a hotel room doesn’t. We manage rentals across San Antonio, New Braunfels, and Canyon Lake.
Schlitterbahn in New Braunfels is the most complete family experience in the region, combining water rides, children’s areas, and a full day of activity. For families staying in the city, SeaWorld San Antonio is the strongest in-city option.
Landa Park in New Braunfels is free and family-friendly. The San Antonio River Walk is free to walk. The Japanese Tea Garden in San Antonio is free to enter.
Yes for the above-ground activities at any age. The Discovery Tour cave is recommended for children 5 and up. Younger children may find the underground environment difficult.
About 30 miles northeast via I-35, roughly 35 to 40 minutes.
