6. Coronado, California
Having been named No. 1 on Dr. Beach’s list for 2012, this 1.5-mile-long beach is back. On Coronado Island across the bay from San Diego, it’s called “the toast of Southern California” by Leatherman for its “lush subtropical vegetation, unique Mediterranean climate and fine sparkling sand.” Before or after the beach, it’s worth visiting the adjacent Hotel del Coronado, a Victorian landmark built in 1888, backdrop for the Marilyn Monroe hit movie “Some Like It Hot,” and Coronado’s main streets has an All-American vibe with brew pubs, classic diners and fine dining.
