Dinner Key Marina offers a glimpse into Miami's past, present, and future all at once. Dinner Key is the famed former home of Pan American Airways' flying boats, and the defunct air carrier's old terminal building now serves as Miami City Hall, the focal point of the lush marina grounds. In its modern incarnation, the marina sits adjacent to Regatta Park, a stone's throw from Villa Vizcaya and a short walk to the shops and boutiques of Coconut Grove's village center. For the boaters and yachties out there, the marina boasts a whopping 582 slips, 24-hour staff and security, concrete docks, and wooden finger piers. Locals and casual boaters can also rent pontoons and kayaks for hours at a time. This is a great spot to anchor down for a while.
