This one isn't exactly easy to find since it's accessible only by a quiet neighborhood road around the corner from buzzing Bonita Beach Park, but it's well worth the effort if you appreciate natural coastal habitats with fun interpretive programs. Shells here are bountiful, as are gopher tortoises that may park in shade of your car. Stop by the nature center to join a ranger-led walk through the trails and gardens, or take up a paddle and go kayaking. There's no towel-jockeying here along the wide-open space (the preserve as a whole is 342 acres), and refreshments and beach rentals provide ample comfort while you unwind in the pristine sands. Amenities: parking (fee); food and drink; showers; toilets; water sports. Best for: solitude; walking.
