The Seashore stretches 160 miles from Cat Island in Mississippi to the eastern tip of Santa Rosa Island in Florida. There are snowy-white beaches, sparkling blue waters, fertile coastal marshes, and dense maritime forests. Visitors can explore 19th century forts, enjoy shaded picnic areas, hike on winding nature trails, and camp in comfortable campgrounds. In addition, Horn and Petit Bois Islands located in Mississippi are federally designated wilderness areas. Nature, history, and recreational opportunities abound in this national treasure.
