Little Inagua was designated a National Park by the Bahamas Government in 2002. It is the largest uninhabited island in the wider Caribbean and maintains its remote, natural undisturbed state. It is a documented nesting location for critically endangered sea turtle species, and its surrounding waters contribute to the supply of fisheries eggs, larvae, and subadults that are swept into the remaining Bahamian marine territory.
Park designation includes the marine area to 100 fathoms, increasing the percentage of marine ecosystem under protection for fisheries replenishment purposes. The approximate area of this National Park is 31,600 acres.
