Belle Isle is a neighborhood in the city of Miami Beach on an island in Biscayne Bay, Florida, United States.

The gateway to Miami Beach earned a reputation as an enclave for fashionable millionaires, such as Joseph H. Adams, whose sprawling estate occupied the southeast corner of the island.

During the Florida land boom of the 1920s, Belle Isle and Fisher's nearby Flamingo Hotel were the site of the famous Biscayne Bay Speed Boat Regattas.

Fisher had successfully promoted automobile races in Indianapolis, and he used his skills to stage gasoline-powered speed boat races in the smooth waters of Biscayne Bay just south of Belle Isle as a spectacle to attract the wealthy and sophisticated tourists that he was seeking as a target audience for his new exotic vacation destination.
