Gulf Islands National Seashore (Mississippi District) protects a chain of barrier islands and coastal mainland areas along the Gulf of Mexico in Mississippi, forming part of the largest national seashore in the United States. The Mississippi district encompasses Ship Island, Horn Island, Petit Bois Island, Cat Island, and the Davis Bayou area near Ocean Springs — together offering white-sand beaches, clear Gulf waters, and some of the most pristine undeveloped coastline remaining in the northern Gulf.
The Davis Bayou area on the mainland near Ocean Springs is accessible by car and serves as the district headquarters. It contains a visitor center, a campground, a boat launch, and several short nature trails through salt marsh and live oak forest. Birding is exceptional here, particularly during spring and fall migration.
Ship Island is the district's most popular destination, reached by a seasonal passenger ferry from Gulfport Harbor. The island offers swimming beaches, nature trails, and the imposing ruins of Fort Massachusetts — a pre-Civil War brick fortification that served as a Union staging point during the war and as a quarantine station thereafter. Snorkeling in the clear, shallow waters around the island is popular in summer. Horn and Petit Bois islands are wilderness islands accessible only by private boat, valued by paddlers and campers seeking true seclusion.
The Mississippi district experiences hot, humid summers with water temperatures in the mid-80s Fahrenheit. Spring is ideal for birding and wildflower viewing in the Davis Bayou area. Hurricane season (June–November) occasionally disrupts ferry service. The $25 vehicle pass covers 7 days; the America the Beautiful annual pass is accepted. Ferry tickets are purchased separately through Gulf Islands Ferry.
