Only an hour and a half drive from Boston, the sleepy seaside villages of the Southern Main Coast — Cape Neddick, Ogunquit, Wells — are a perfect alternative to vacationing in overcrowded Nantucket or Cape Cod. Soak up the sun at the breezy Ogunquit Beach, sightsee along the New England coast, or book a boat cruise to learn what it takes to catch a delicious Maine lobster. Secure a reservation at theClay Hill Farm Restaurant, where the fresh cuisine trumps the idyllic sprawling acres around you.
