1. San Diego, CA
With sunny beaches, fantastic theme parks, and the world’s largest comic book convention, there's no such thing as bored children in sunny San Diego. Plus, like a good Pixar flick, the best kid-friendly activities won’t leave adults gaping at their phones. We promise parents will love mingling with exotic animals, splashing through waterfront fountains and marveling at towering Lego sculptures right alongside the kids. Avoid rowdier crowds and embrace calm waves alongside other families at Mission Beach, Coronado Beach or La Jolla Shores.
