White quartz sand, Gulf barrier islands, and centuries of coastal forts spanning the Florida, Alabama, and Mississippi shoreline.
Gulf Islands National Seashore
Gulf Islands National Seashore is an American national seashore that protects a chain of barrier islands and mainland areas along the northern Gulf of Mexico, distributed across the coasts of Florida, Alabama, and Mississippi. Authorized in 1971 and administered by the U.S. National Park Service, the seashore preserves a distinctive mix of bright white quartz-sand beaches, historic coastal fortifications, maritime forests, and open Gulf waters spread across more than a dozen non-contiguous units.
The protected landscape is unusually varied for a single national seashore. The Florida District includes the offshore barrier islands of Santa Rosa and Perdido Key, mainland reserves such as Naval Live Oaks near Gulf Breeze, and a cluster of nineteenth and twentieth century forts around Pensacola Bay. The Mississippi District is a quieter, more remote set of mainland bayous at Davis Bayou and boat-access barrier islands that include the federally designated Gulf Islands Wilderness.
Together, these districts form one of the most visited units in the National Park System, drawing millions of visitors each year for swimming, fishing, camping, and historical sightseeing. The seashore also serves as a working laboratory for barrier island geology, Gulf ecology, and the long process of recovering from major storms and oil spills.
