Highland Beach has around 4,000 year-round residents, a figure that just about doubles over the winter months. There are fewer operating businesses here than you can count on one hand, setting the relaxed pace you'd expect for a town that lies entirely on a barrier island. Its pleasures are simple but plentiful: Natural treasure is everywhere if you know where to look — like Yamato Rock, a meteor-esque limestone outcropping right off shore that's a popular fishing and snorkeling spot. Latitudes, at Delray Sands Resort, offers fine oceanfront dining, and a full spectrum of restaurant options lies right across the Intracoastal in Boca and Delray.
