Located in the Outlying Islands of the Florida Keys, it is one of the Mule Keys that are 9 miles (15 km) west of Key West. Because the island's 13 acres are privately owned by David W. Wolkowsky through the David W Wolkowsky Trust, Key West is incorrectly assumed to be the southernmost point in the continental U.S. The southernmost point in the entire U.S. is Ka Lae, Hawaii.
The island had a cameo appearance in the Bond movie License to Kill.
The island features four bedrooms & a master suite with a fully equipped three bedroom guesthouse overlooking a palm tree lined beach. Water is supplied by desalinization.
The island has two private residences and was for sale as of early 2007.
