Sugarloaf Key is a single island in the lower Florida Keys that forms a loop on the Atlantic Ocean side giving the illusion of separate islands. Although frequently referred to simply and with technical accuracy as "Sugarloaf Key", this island contains two distinct island communities, known as Lower Sugarloaf Key and Upper Sugarloaf Key. The island is somewhat "U"-shaped, with Upper Sugarloaf Sound and Park Key separating the island into Upper Sugarloaf Key and Lower Sugarloaf Key. So called, upper and lower, simply referencing the relative nature of their geographic positions, not as distinct islands. Lower Sugarloaf Key is located approximately 13 miles from Key West, between Park Key and Saddlebunch Keys. Upper Sugarloaf Key is located about 15 miles east of Key West, between Park Key and Cudjoe Key. While smaller in land area than Upper Sugarloaf Key, Lower Sugarloaf Key has a greater density of population.
