Once a little-known secret, this out-of-the-way park encompassing 1,616 acres on four barrier islands and several uninhabited islets is popular among beachgoers and birders. Bike, hike, walk, or paddle the park's trails (rentals available); go shelling on its 2½ miles of white-sand beach; take a boat tour; or have a beach picnic under the trees. Trams run regularly from 9 to 4:30 to deliver you and your gear to South Beach. The ride is short but often dusty. North Beach
is a five-minute walk from the concession area and parking lot. Watch for osprey, bald eagles, herons, ibis, pelicans, and roseate spoonbills, or sign up for a free excursion to learn fishing and nature photography. On the park's bay side, across the road from the beach entrance, playgrounds and a picnic area cater to families, plus there are boat ramps, kayak rentals, and a bait shop. Amenities: food and drink; parking (fee); showers; toilets; water sports. Best for: swimming; walking.
