Why simmer in summer traffic for six hours en route to Cape Cod when Manchester-by-the-Sea’s SINGING BEACH on Cape Ann is right up the road? Sure, it’s not easy to park (the nearest lot is a half-mile away), and there aren’t many non-aquatic attractions in sleepy Manchester. But do you actually need a neon-streaked boardwalk when you have the softest sand in Massachusetts, a pristine blue sea, and craggy cliffs perfect for privacy? Clean bathrooms, too.
