Splash around at the fountain just off the shore at Indian Riverside Park in Jensen Beach.

Best Things To Do with Kids in Martin County, Florida

1. Public Beaches

Beach season starts early and ends late in this part of Florida. Locals love to swim and sunbathe at Stuart Beach, which has a lifeguard on duty and is within walking distance to some of the city's museums. Meanwhile, Ross Witham Beach boasts a real-life shipwreck that snorkelers and scuba divers can explore. It's also home to the Georges Valentine Underwater Archaeological Preserve, located about 100 yards off shore.

My kids' favorite Martin County beach is Indian Riverside Park in Jensen Beach. The water is calm in the lagoon, and the mangrove trees make for a beautiful landscape. Bonus: Just off the sand is an interactive fountain where kids can splash their hearts out.

2. Children's Museum of the Treasure Coast — Jensen Beach

Kids with a fondness for pretend play will go wild for this museum next to Indian Riverside Park. It has a mini fire station, bank, grocery store, and vet clinic, as well as a giant pirate ship with plenty of interactive features. Outside is a sweet children's garden with musical instruments and small play structures. The museum will especially appeal to the 8 and under crowd, though my older daughter enjoys coming with her little sister. Check the website for special events, sensory-friendly days, and discounts.

Take a boat tour at Jonathan Dickinson State Park to catch a glimpse of the turtles and other animals.

3. Jonathan Dickinson State Park — Hobe Sound

Biking, hiking, and kayaking are just a few of the amenities offered at this stunning state park on the Loxahatchee River. In addition to being my family's go-to local campsite, the park offers unique boat tours that I love, like a guided tour of Trapper Nelson’s homestead. Known as the "wildman of the Loxahatchee," Nelson lived off the land by trapping and selling furs and keeping his own zoo of exotic animals. FYI: Parking at the park is $6 per vehicle.

4. Elliott Museum — Stuart

More than 90 cars and trucks, as well as boats and an airplane, are on display at this museum located just across the street from the Florida Oceanographic Coastal Center. Baseball lovers will enjoy the Elliott's collection of autographed cards, bats, and other artifacts. The museum also hosts rotating exhibits featuring local photographers and artists.

5. Blowing Rocks Preserve — Hobe Sound

Observe a natural spectacle at the Blowing Rocks nature preserve on Jupiter Island. Owned by the Nature Conservancy, this beach contains the largest Anastasia limestone outcropping on the state's east coast. That means that when breaking waves hit these rocks, plumes of salt water can shoot up to 50 feet in the sky. The beach is also an excellent place for collecting colorful seashells.

6. Halpatiokee Regional Park — Stuart

This rugged park, the largest in Martin County, really showcases the wilder side of Florida. Outdoor enthusiasts love the miles of hiking and mountain bike trails, as well as renting a kayak or canoe to explore the South Fork of the St. Lucie River. If you're hoping to spot a Florida gator, this park may be your lucky spot—alligators are often seen here, along with turtles and birds of prey.

You never know what you'll see at the Florida Oceanographic Coastal Center.

7. Florida Oceanographic Coastal Center — Stuart

Learn about Florida's amazing wildlife and coastal ecosystems at this 57-acre nature center. There are plenty of opportunities for kids to interact with the animals, including an invertebrate touch tank with hermit crabs, sea cucumbers, and urchins.

Even more fish are on display in the center's indoor museum, which also features hands-on puzzles and games.

8. Hobe Sound Nature Center — Hobe Sound

Visit with snakes, baby alligators, birds of prey, and more at this small nature center that offers free admission to all (parking is also free). Outside the museum is an expansive trail network where you're likely to spot even more wildlife like lizards and turtles. Plus, you can access a beautiful and quiet beach from the center's parking lot, so definitely pack some swimsuits and sunscreen.

The Pontiki family tour allows guests to get off the boat to swim or snorkel.

9. Pontiki Boat Tour — Stuart

Embrace those island vibes on a cruise up the Intracoastal Waterway. The Pontiki family tour leaves from the Hutchinson Island Marriott Resort on Saturday mornings and select weekdays. The boat parks at a sandbar where cruisers can get off to swim, snorkel, toss a Frisbee around, and enjoy the stunning scenery. The experience lasts about two-and-a-half hours. FYI: Pontiki also cruises out of Jupiter, Florida and is available for private charters.

10. Kiwanis Park — Stuart

On those gorgeous Florida weather days (and there are plenty of them), head to one of Martin County's top outdoor playgrounds, Kiwanis Park. This accessible park is known for its unique structures like mini houses, roller tunnels, seesaws, and dinosaur riders. There's also a variety of swings and plenty of sand for those kids who like to dig. A covered pavilion with picnic tables makes for a great lunch spot, too.

If you're looking for a great place to cool off this summer, look no further than Sailfish Splash Waterpark.

11. Sailfish Splash Waterpark — Stuart

My family adores this water park that has great all-age attractions, yet feels contained enough that you can easily keep an eye on your kids. Along with two water slides that are four stories tall, the park has a 1,000-foot lazy river, a kids' obstacle course, and a giant splash playground with sprays, slides, and that perennial favorite, the big dump bucket. There are lots of shaded lounge chairs and picnic tables, as well as a snack bar that sells hot dogs, snacks, and pizza. The water park is closed during the fall and winter, so check the calendar before visiting.
