Come the fall, there are few landscapes as dramatically transformed as the ones you'll encounter along Eastern Canadian and New England coastlines. When Mother Nature works her autumnal magic, the vistas explode with vibrant colors, setting off the region's historic lighthouses, majestic mansions, and cosmopolitan cities in spectacular fashion. The grandeur extends inland, too – from Boston's Common to Montreal's fashionable boutiques and the fortified ramparts that surround Old Québec – and luxury cruising's agile vessels are uniquely equipped to carry you there.
