    Explore Miami

    The Magic City—home to a thriving nightlife scene, world-class art galleries, breathtaking sandy beaches, and the best Cuban food you’ll eat outside the country itself. Get acquainted with the vibrancy of the area by starting off your trip with a visit to the Art Deco Historic District in Miami Beach. Walking along Ocean Drive and Collins Avenue, you can admire the pastel hotel and restaurant buildings with nostalgic neon signs that characterize this dynamic neighborhood. If you want to see more architecture, design, and art, head over to the Pérez Art Museum Miami (PAMM). Architecturally significant in its own right, this concrete, glass, and wood modernist building houses an extensive permanent collection of contemporary art.

    Of course, no visit to Miami would be complete without plenty of time spent soaking up the sun. One popular spot for locals and tourists alike is South Beach, a beautiful white-sand destination located on the southern side of Miami Beach. Clear, shallow water and a generous sandy area make South Beach the perfect spot for swimming, sunbathing, or playing a game of beach volleyball. Equally scenic is Lummus Park Beach, which has grassy areas in addition to sand. Stroll down the promenade and stop at one of the boardwalk restaurants for a snack, catch up on some beachside reading under a palm tree, or head straight to the surf to dip your toes in the bright blue water.
