Given its close proximity to Key West, Sugarloaf Key is a popular place to live. It got its name from the sugarloaf pineapple as there used to be a pineapple plantation on the island. There are two distinct island neighborhoods, Upper Sugarloaf Key and Lower Sugarloaf Key, although Sugarloaf is, in fact, one island. The Great White Heron National Wildlife Refuge is located in Upper Sugarloaf Key, as are two public schools. Lower Sugarloaf Key is home to the Sugarloaf Bat Tower, a national historic landmark. Waterfront and water access properties are abundant on Sugarloaf Key.
