Sailfish Splash Waterpark
Beat the heat with a trip to Sailfish Splash Waterpark. It’s known for competitive swimming and diving, but the real excitement comes in the form of a 1,000-foot Lazy River in addition to a four-story water slide and speed slides. When not swimming, enjoy an alfresco picnic or relax in a private cabana. $14.45/child day pass, $16.45/adult day pass
Kiplinger Nature Preserve
Round up the kids for a day of adventure at Kiplinger Nature Preserve, a 157-acre natural area in Stuart. Hike along footbridges and scenic trails or launch a kayak or canoe. There’s a diverse mix of freshwater and mangrove swamps, wet prairies, and estuaries, so you’ll have many chances to encounter native wildlife, including snowy egrets and alligators.
St. Lucie County Aquarium
Education doesn’t need to stop once school breaks for summer. Take the kids to the St. Lucie County Aquarium in Fort Pierce to explore six different Florida marine and estuarine ecosystems, including the largest display of a living Caribbean coral reef. There are also reef habitats, mangroves, seagrass—and up-close encounters with local marine life. $3.25/general admission
