Here’s the thing about Florida: You visit time and again, and you're quite sure you know the state and its glorious sandy stretches pretty well. But there’s always a surprise waiting for those who stray from the classic Panama City–Orlando–Miami–Key West stops. From Atlantic coast enclaves that locals try to keep to themselves to subtropical islands dotting the Gulf of Mexico, most of our picks for under-the-radar Florida beach towns won’t ring a bell, but consider that a good thing. Get away from the vacationing masses for a taste of old Florida in these spots where the simple things—sun, surf, and a no-worries attitude—still reign. —Terry Ward
