Visiting Nantucket town can be like stepping back in time. The charming, cobblestoned streets are paved with stone originally used as ballast in ships arriving into port in the 17th century, and there are no stop lights. You won't find big-box stores, but independently owned boutiques selling unique and carefully curated collections of gifts, clothing, and jewelry. Window boxes overflowing with miniature cottage gardens decorate and differentiate the rows of uniformly shingled storefronts. Intermixed with all this charm are world-class dining establishments serving just-off-the-docks seafood and creative small plates, among other things. Wander down to the harbor and the shell-covered paths on Old South Wharf. Weathered fishing shanties, most now small shops and galleries, are covered in roses and accented with blue and purple hydrangeas. Stroll the nearby pier during high season and see eye-popping luxury yachts lining the docks, their sparkling hardware gleaming in the sunshine.
