Castaway Cove is a gated community on the barrier island divided into five subdivisions, or "waves", located on both the east and west side of A1A. Waves II and IV are situated west of A1A while waves I, III and VI are east of A1A. Castaway Cove as an entirety is comprised of just over 400 homes that vary in size and design. The neighborhood itself is friendly and family-oriented. Residents enjoy community beach access with a pavilion, showers, a boardwalk and bike racks.
