Kailua Beach Park, a 3-mile windward stretch of beach on Oahu’s eastern shore, ranks number one as the best beach in the United States. Located a 30-minute drive from Honolulu, the beach is beloved for its soft sand and impossibly clear water. You’ll also find family-friendly amenities, including lifeguards, free parking, picnic tables, barbecue grills and freshwater showers. Because of all the extras at this park, this beach is popular with locals, especially on weekends. It’s also a favorite among windsurfers and kitesurfers for the steady breezes.
