If you are really committed to exploring Miami, the city can keep you entertained for weeks. But sometimes a good 'ol road trip is necessary, especially with Miami's proximity to so many entertaining destinations.
Key West is the most well-known of this string of islands. But consider that Key West is the southernmost tip of the state (only 90 miles from Cuba!) so there are plenty other destinations in the Florida Keys that are on the way or instead of going so far south. To generalize, each of these islands offers expected outdoor activities such as diving and an assortment of water sports. Some visitors even plan trips around getting certified to scuba dive. Key Largo, for example, is less than an hour (without traffic) from Miami proper, whereas Key West is about three and a half hours away. Dozens of stops in between Miami and Key West yield opportunities for great water activites, outdoor fun, and relaxation.
