"Distance from Boston: 79.5 miles What's the water like? Warmer bayside waters that transform drastically with the tides throughout the day—from small, quiet waves to miles of tidal pools. Why we love it: Low tide. The beach drains out more than a quarter of a mile, giving way to expansive views and sand flats, attracting families, photographers, and those just in awe of the ocean. Go early to beat inevitable skimboard-, volleyball-, and sand toy-toting crowds." - Cassie Shortsleeve
