7 Best Sights in Fort Pierce and Port St. Lucie, Palm Beach and the Treasure Coast

Across the inlet at the northern side of Hutchinson Island, a fishing oasis lures beachgoers who can't wait to reel in snook, flounder, and bluefish, among others. The park is also known as a prime wave-riding locale, thanks to a reef that lies just outside the jetty. Summer is the busiest season by a long shot, but don't be fooled: it's a laid-back place to sun and surf. There are covered picnic tables but no concessions; however, from where anglers perch, a bunch of casual restaurants can be spotted on the other side of the inlet that are a quick drive away. Note that the area of Jack Island Preserve has been closed indefinitely. Amenities: lifeguards (summer only); parking (fee); showers; toilets. Best for: solitude; surfing; walking.

Kids get a thrill out of the helicopters and aircraft on the grounds.

Housed in the St. Lucie County Aquarium and run by the Smithsonian Institute, whose research facility next door is where scientists study local ecosystems (once-monthly tours are organized), this facility has a 3,000-gallon coral-reef tank, originally located in the National Museum of Natural History in Washington, D.C. The parklike setting, where children love to play, makes it an ideal picnic destination. Admission is free on the first Tuesday of every month.

Highlights here include a Seminole dugout canoe, pictures from the Hill Photographic Collection, and a life-size re-creation of the P. P. Cobb General Store. A room is also devoted to the U.S. Navy Amphibious Training Base of World War II, which was located on St. Lucie's beaches. A guided tour of the Gardner House (the 1908 home of the Register family), with furnishings typical of the period, is included in the price of admission.
