Best Summer Activities for Kids in Stuart, FL

Stuart is one of those rare Florida towns where a beach morning, a hands-on nature stop, and a downtown stroll can all fit into the same day. That mix makes it especially strong for families who want summer fun without the all-day, theme-park-style commitment.

Why Stuart works in summer

Stuart works best for families because it gives you variety without forcing constant logistics. You can do marine life, waterpark thrills, calmer beach time, free downtown entertainment, nature trails, and indoor educational stops all within the same trip.

1

Spend a morning at the Florida Oceanographic Coastal Center

If you only choose one distinctly Stuart activity, make it the Florida Oceanographic Coastal Center. It is the strongest mix of summer fun and actual local marine-life education without feeling like a school field trip.

  • Open daily from 10 a.m. to 4 p.m., with current listed admission of $20 for adults, $10 for children ages 3 to 12, and free for children 2 and under.
  • Combines stingray interactions, a gamefish feeding program, sea turtle talks, the Ocean EcoCenter, and a one-mile nature trail through mangrove habitat.
  • Best fit: families who want animals, hands-on moments, and enough real ecology to keep older kids engaged too.

Cool off at Sailfish Splash Waterpark

For pure summer energy, Sailfish Splash Waterpark is hard to beat. It is the most reliable answer for mixed-age families because it gives everyone a lane instead of forcing all kids into the same kind of water play.

  • Martin County describes a two-acre facility with a 1,000-foot lazy river, two four-story water slides, a zero-depth-entry interactive splash playground, shaded picnic areas, cabanas, and a lap pool area.
  • Located in Stuart at 931 SE Ruhnke Street.
  • Best fit: high-heat summer afternoons when little kids need gentler play and bigger kids want something more exciting.

Pick the right beach for your kids' ages: Bathtub Beach or Stuart Beach

Not every family beach day in Stuart should look the same. The real trick is choosing the beach that matches the age mix and energy level you have that day instead of treating every shoreline the same.

  • Bathtub Beach is usually the better bet for many families with younger children because Martin County says the offshore reef helps break waves during calmer spring and summer conditions.
  • Stuart Beach is the stronger choice when your kids want a fuller beach-park setup with covered picnic areas, volleyball courts, basketball courts, showers, bathrooms, and food nearby.
  • Smart rule: treat Bathtub as the calmer-water, shorter-visit beach and Stuart Beach as the longer, higher-energy day.

Build a free downtown day around the Riverwalk

Historic Downtown Stuart is one of the town's biggest advantages for families because it turns simple activities into a real outing. It gives parents an easy, low-pressure summer formula that does not require a formal attraction ticket.

  • Market on Main is held every Sunday, year-round, at Flagler Park along the St. Lucie River with live music each week and a Kids Market section on the third Sunday of each month.
  • Downtown also hosts the free Rock'n Riverwalk concert series every Sunday from 1 p.m. to 4 p.m. on the waterfront.
  • Shepard Park adds tropical walkways, a fishing dock, a playground, picnic space, and a Riverwalk boardwalk if you need a nearby play break.

Add one indoor culture stop: the Elliott Museum

The Elliott Museum is one of the better rainy-day or mid-afternoon options in Stuart because it is broad enough to interest adults without losing kids entirely. It works best as a cool-down outing after the beach or before dinner.

  • The museum highlights local history, temporary exhibits, vintage cars, baseball, artwork, and Americana.
  • It offers handheld Guide-ID audio devices with more than 30 exhibit stops, which can help older children engage more actively.
  • Best fit: families who want one air-conditioned stop that gives the trip more texture than just sun and water.

Trade screens for trails at Halpatiokee Regional Park

If your kids need room more than they need attractions, Halpatiokee Regional Park is a strong summer reset. It is one of the best ways to make Stuart's river-and-trail side part of the trip instead of only doing beaches.

  • Martin County says the park includes hiking trails, biking trails, paddling trails, river frontage along the South Fork of the St. Lucie River, and sports fields, courts, and picnic areas.
  • The county-wide paddling trail system spans 37.7 miles across the Indian River Lagoon and St. Lucie River systems.
  • Best fit: older elementary kids, tweens, or teens who get restless at museums but still need some structure.

Use the library for air-conditioned summer fun

A high-value Stuart summer plan should include at least one free indoor fallback, and the Martin County Library System is excellent for that. Libraries help a family trip feel more sustainable instead of becoming one long cycle of beach, snack, sunscreen, repeat.

  • The 2026 Summer Reading Program runs from May 29 to August 9.
  • For kids from babies through fifth grade, the program rewards reading with free books, and kids who reach 30 days of reading receive an invitation to the finale party plus a free-admission pass to Sailfish Splash Waterpark while supplies last.
  • The library also offers weekly story times designed to build early literacy skills and vocabulary.

Stretch the map slightly for Indian RiverSide Park and the Children's Museum

For families staying in Stuart, nearby Jensen Beach adds two especially useful kid-friendly stops. This pairing is especially strong for toddlers and elementary-age kids because it gives you both active outdoor play and a hands-on indoor backup in one area.

  • Indian RiverSide Park is a 63-acre family destination park with a waterfront path, mangrove boardwalk, 780-foot fishing pier, beach, picnic areas, and a free interactive play fountain.
  • The park is also home to the Children's Museum of the Treasure Coast, which centers its mission on hands-on activities, educational programs, and cultural experiences.
  • Best fit: families who want both a fountain-and-boardwalk outdoor stop and an indoor museum backup without a major detour.

A simple 3-day summer game plan

An easy way to shape the trip.

Day 1

Florida Oceanographic in the morning, then Stuart Beach for lunch and a shorter beach session. The locations sit on the same corridor, so the transition is easy.

Day 2

Sailfish Splash Waterpark for the all-in water day, especially if the kids want slides and a lazy river rather than salt water and sand.

Day 3

Downtown Stuart for Market on Main and Riverwalk time, or swap in the library, Elliott Museum, or Indian RiverSide Park when you want more shade and less heat exposure.

Practical tips for parents

Heat and swim safety

Treat safety and heat as part of the itinerary, not as afterthoughts. Martin County Ocean Rescue staffs guarded beaches year-round, publishes lifeguard hours, and provides a beach information hotline. Checking the beach warning flag before swimming should be non-negotiable.

Accessibility

Martin County says beach wheelchairs are available at guarded locations including Stuart Beach on a first-come, first-served basis at no charge through lifeguards.

Current closure note

If you were considering the House of Refuge, the official site currently says the museum is closed for renovation, so check status before adding it to your summer schedule.
