Fisher Island
Area:
Simply Fisher Island
Fairly small island, technically part of Miami Beach, Fisher Island is privately owned and has highest per capita income in the United States. Home to many millionaires, stars from different fields of business or sports.
There is no road or other way of transportation besides private boats or a ferry. If you want to see this from a close distance, it would be the best if you hop on one of the boat tours around the island.
