Gulf Islands National Seashore

Gulf Islands National Seashore is a 12-unit National Park that protects barrier islands along the Gulf Coast of Mississippi and Florida. Established in 1971, the park preserves pristine white sand beaches, historic military fortifications, and unique dune ecosystems that were shaped by centuries of hurricanes and ocean currents. The Mississippi district, centered around the Davis Bayou Area and accessible barrier islands, offers some of the finest undeveloped beach experiences on the Gulf of Mexico.

The park's landscape is defined by bright white quartz sand — washed down from the Appalachian Mountains over millennia — forming towering dunes held in place by sea oats and beach grass. Four of the seven world sea turtle species nest here, and twenty endangered species call the park home, including the famous Perdido Key beach mouse. The Mississippi islands — Cat Island, East Ship Island, Horn Island, and Petit Bois Island — provide quiet retreats for camping, birdwatching, and fishing far from any development.

Climate is subtropical: sunny and warm most of the year with humidity peaking June through September. Afternoon thunderstorms are common in summer, and hurricane season runs June through November. Many areas are periodically closed due to storm damage, so always check the park website before visiting. The best time to visit is spring (March–May) or fall (September–November) when temperatures are more comfortable.

The Davis Bayou Area is the only accessible mainland portion of the Mississippi District and can be explored on foot or by bike via the 15.5-mile round-trip Live Oaks Bicycle Route, which connects to Ocean Springs. Accessing the barrier islands requires private boat or the Pan Isles passenger ferry (Gulfport Yacht Harbor, +1-866-466-7386), which runs March through October to West Ship Island. Horn Island, Petit Bois Island, and East Ship Island are open year-round to private boaters.
