Best Things to Do in Port St. Lucie, FL With Kids
Port St. Lucie's family days center on the calmer inlets of the Treasure Coast and the Indian River Lagoon: a manatee-season kayak tour, a beach afternoon in Fort Pierce or Jensen Beach, an NY Mets spring training game at Clover Park (February–March only), and a Hutchinson Island day that pairs the beach with the Elliott Museum or the Navy UDT-SEAL Museum.

Guided kayak tours launch where manatees congregate in the cooler months, and the lagoon water is calm and shallow enough that even first-time paddlers can focus on watching rather than fighting the boat.
Watch out: Sightings aren't guaranteed; manatees move with water temperature, so an unusually warm winter week can mean fewer animals near the launch point. Ask the outfitter about that week's activity before booking. Swimming with manatees is not permitted at this location.

Fort Pierce Inlet State Park has calmer swimming inside the jetty and open surf outside it, while Jensen Beach is quieter and better suited to shell hunting with young kids who aren't up for waves.
Watch out: Currents near the inlet jetty can be strong, so stay inside the marked swim area, not on or near the rocks. Lifeguards aren't posted at every beach access point; check which one before you go.

Grapefruit League games run mid-February through March only. The stadium is small enough that seats are genuinely close, and pre-game autograph chances are real in a way they aren't at a regular-season ballpark.
Watch out: Strictly seasonal; there is nothing to do here the rest of the year. Weekend games against Miami, Washington, or Houston sell out, so buy ahead rather than assuming walk-up tickets.

Hands-on exhibits, including a kids' Main Street, vintage cars, and a dedicated play area, sit a five-minute walk from a calm stretch of Hutchinson Island beach, so museum and beach time don't require moving the car.
Watch out: Smaller than the name suggests; plan on two hours, not a full day. Pair it with the beach or the UDT-SEAL Museum next door to make the drive out worthwhile.

Real Navy frogman and SEAL history and equipment on the same beach where the original training happened, including outdoor exhibits like a helicopter and dive vehicles. More engaging for older kids than a standard local museum.
Watch out: Some combat-history content is a better fit for 8 and up than for younger kids. It's a smaller operation partly run by volunteers, so hours shift seasonally; confirm before driving out.
Frequently asked
When can we actually see manatees near Port St. Lucie?
Roughly November through March, when cooler water pushes manatees into the warmer channels of the Indian River Lagoon system. Summer sightings are much less reliable.
Is Mets spring training worth building a trip around?
Only if your trip already lands in February or March. The games are genuinely fun and the stadium is small enough to feel close, but this is strictly seasonal with nothing to substitute the rest of the year.
What's the best beach for young kids?
Jensen Beach for calm shell hunting, or the inside-the-jetty section of Fort Pierce Inlet State Park if you want a lifeguarded swim area close to open surf for older kids.
Can we do the Elliott Museum and the UDT-SEAL Museum in one day?
Yes. They're next to each other on Hutchinson Island, and adding an hour of beach time on either side makes for a full, well-paced day.
