Gulf Islands National Seashore Visitor Guide (Ocean Springs)
Gulf Islands National Seashore is the largest protected area on the northern Gulf Coast, running from Cat Island off Mississippi through a chain of barrier islands and into the Florida Panhandle. From Ocean Springs, you can access two distinct parts of it: the Davis Bayou Unit, which is right on the east edge of town, and the barrier islands, which require a ferry.
Most visitors treat the two as separate trips and they are correct to do so. They offer different things.
The Davis Bayou Unit: What It Is and How to Use It
The Davis Bayou Unit sits off Park Road on the east side of Ocean Springs, about five minutes from downtown. Entry is free and no reservation is needed. The visitor center, operated by the National Park Service, is the place to start. Rangers there can give you a current trail map, tell you what birds are active, and explain the camping options.
The unit covers a stretch of bayou, marsh, and maritime forest that is genuinely quieter than most people expect from a park this close to a town. The trails through the maritime forest take you past old live oaks with Spanish moss and through understory that is nothing like what you find in the upland parts of Mississippi. Plan for 60 to 90 minutes if you are doing the main trail loop.
The Live Oaks Bicycle Route runs through the Davis Bayou Unit and is one of the more scenic flat rides on the Gulf Coast. Families with bikes will find it manageable. It follows shaded roads through the park and the surrounding area.
The fishing pier at Davis Bayou extends over the water and is free to use. Redfish, speckled trout, and flounder are in these waters, and crabbing from the pier is a reliable activity for kids. The campground adjacent to the pier takes reservations through Recreation.gov and fills up quickly on fall weekends. The sites are pull-through for RVs and also accommodate tents. It is the only developed campground in Ocean Springs and one of the better camping options on the Mississippi Gulf Coast.

The Barrier Islands: Horn Island and West Ship Island
The barrier islands are the part of Gulf Islands National Seashore that looks like what people imagine when they hear “Gulf beach.” Fine white sand, clear water, waves from the open Gulf, and almost no development.
Horn Island is the closest barrier island to Ocean Springs and has a reputation among artists because Walter Anderson paddled out there repeatedly over the last decades of his life and painted obsessively from what he found. The island is primitive and wild. No ferry service runs directly to Horn Island for general visitors. Getting there requires a private boat or a charter out of the Ocean Springs harbor. It is a serious trip, not a day-trip for the unprepared.
West Ship Island is more accessible. Ferry service to West Ship Island runs from Gulfport, not from Ocean Springs, and the crossing takes about an hour. The beach on the Gulf side of the island is wide, white, and protected by the island’s location from the strongest current. There is a Civil War-era fort on the island, Fort Massachusetts, that the Park Service maintains and offers tours of during ferry season. The ferry operates seasonally, typically spring through fall, and tickets sell out on weekends. Book ahead if you are going in summer.
Bring everything you need for the day. Food and water on the island are limited or unavailable depending on the season, and shade is scarce.
Park Passes and Fees
As of 2026, the Davis Bayou Unit has no entry fee. The barrier island ferry is a separate commercial operation with its own pricing. The America the Beautiful annual pass covers entrance fees at National Park Service sites and is worth the cost if you visit more than a few national parks per year.
The Interagency Annual Pass also covers the campground entrance fee but not the individual campsite reservation fee, which is paid through Recreation.gov.
Birding at Gulf Islands
Gulf Islands National Seashore is one of the better birding destinations on the Mississippi Gulf Coast. The Davis Bayou Unit in particular sits along the Mississippi Flyway, and the marsh-edge habitat concentrates shorebirds, wading birds, and waterfowl at different times of year. Spring and fall migrations bring warblers through the maritime forest in numbers.
The Davis Bayou campground is surrounded by good birding habitat. If you are camping there and willing to be out at dawn, you will find more birds in an hour of walking than most people see all day. The beaches guide covers the waterfront shorebird activity. For the full list of parks and outdoor sites in Ocean Springs, see the best parks in Ocean Springs.
Planning Your Visit
For the Davis Bayou Unit: park on weekday mornings if you want the trails to yourself. The campground is busiest on fall weekends around the Peter Anderson Festival in November.
For the barrier islands: book the West Ship Island ferry at least two weeks out for any summer or fall weekend trip. Bring sunscreen, water, and food for the full day. The ferry schedule constrains how long you can stay, so read the departure times carefully before you go.
