Miami Beach can become very crowded especially parallel to all of the art deco buildings on Ocean Drive. So if you want to enjoy the Atlantic Ocean without sharing the sand with so many people, head towards the east side between 5th and 15th Streets. Here you will find the 74-acre Lummus Park. After too much sun, you can then sit on the grassy areas that are shaded by palm trees. There is also a long pedestrian walkway that is called the Promenade.
