For many of us, summer is the best season of all, when everything moves outdoors, cities come alive with festivals, and freshwater lakes and backyard pools beckon. Our list of top summer destinations highlights the best spots to be at the height of the season, from northern capitals that truly flourish from June through Labor Day, to cool seaside and lakefront retreats that refresh and rejuvenate. Of course, nothing is more quintessentially North American come summertime than a canoe and camping trip – don't worry, we've got you covered there, too.
