In the United States, a beach vacation often means squeezing your towel onto a packed, noisy stretch of sand. But if you know where to look, you can find solitude without having to travel to the Caribbean. Our picks here aren’t the coastal hubs you already know about. They’re charming, under-the-radar spots with sprawling, empty stretches of shoreline, low-key lodging, and an I-wanna-be-here-now vibe. If you’d rather stay in a rustic bungalow with ocean views than a flashy megaresort on the water, these are the seaside destinations for you.
