Belize
People flock to Belize for access to its pristine Placencia Peninsula. Many think this area looks like an island, but the nearly 20-mile stretch of shoreline is actually part of the mainland and is easily accessible by car. The water is typically calm, making it a family-friendly beach spot. The peninsula is also home to three villages, giving beachgoers easy access to plenty of shops and restaurants when they need a break from the sand. For additional beaches, head to one of the islands off the coast of Belize. Noteworthy options include scenic Ambergris Caye and tiny Goff's Caye.
