The southern access for the Canaveral National Seashore, remote Playalinda Beach has pristine sands and is the longest stretch of undeveloped coast on Florida's Atlantic seaboard. You can, however, see the shuttle launch pad at Cape Kennedy from the beach. Hundreds of giant sea turtles come ashore here from May through August to lay their eggs. Fourteen parking lots anchor the beach at 1-mile intervals. From Interstate 95, take Exit 249 and head east. Bring bug repellent in case of horseflies, and note that you may see some unauthorized clothing-optional activity. Amenities: lifeguards (seasonal); parking (fee); toilets. Best for: solitude; swimming; walking.
