Gulf Islands National Seashore, seen in today's image, spans the northern Gulf of Mexico along the coasts of Florida and Mississippi, United States. The national seashore is managed by the National Park Service. Established in 1971, it boasts kilometres of white sand beaches, historic fortifications and rich wildlife habitats. The seashore includes a 16-square kilometre wilderness area on Mississippi's Petit Bois and Horn Islands, protecting these regions' unique ecosystems. The Mississippi District of the seashore offers many attractions, including untouched natural beaches, historic landmarks, wildlife sanctuaries and boat-accessible islands. The National Seashore offers two developed campgrounds, one in Florida and the other in Mississippi, along with designated spots for primitive camping.
