Gulf Islands National Seashore: Visitor Guide & Camping (Mississippi)
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, two distinct parts of it are reachable: the Davis Bayou Unit on the east edge of town (free, no reservation, open daily), and the barrier islands offshore, accessed by ferry from Gulfport or by private boat.
Two clarifications most visitors need up front. The Mississippi District of Gulf Islands has no entrance fee for the Davis Bayou Unit, despite what some out-of-state visitors expect from National Park sites. And the Ship Island ferry leaves from Gulfport, not Ocean Springs — that is a 25-minute drive west. Plan accordingly.
Where to Start: The Davis Bayou Unit (Free)
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 William M. Colmer 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 shorter Nature’s Way Loop is 0.45 miles, about 30 minutes, and is the right pick for families with younger kids.
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. Swimming in the bayou is prohibited because of alligators and venomous snakes; the open Gulf is the place for swimming. For a dedicated guide to the area including the kayak launch and birding spots, see the Davis Bayou guide.
Camping at Davis Bayou
The Davis Bayou Campground is the only developed campground inside Gulf Islands National Seashore’s Mississippi District, and it is the only developed campground in Ocean Springs. It is also one of the better camping options on the Mississippi Gulf Coast.
The facts:
- 52 sites with electric and water hookups. Pull-through options for RVs and tent sites with shade.
- $22/night for a standard electric site (current National Park Service rate; subject to change).
- Reservations through Recreation.gov or (877) 444-6777, available up to 6 months in advance.
- Check-in 1 p.m., check-out 11 a.m. Gate closes at sunset; the gate code is emailed with your reservation.
- Bathhouse facilities maintained by the Park Service. Sites are reasonably level.
Fall weekends, particularly around the Peter Anderson Arts and Crafts Festival (first weekend of November), sell out months in advance. Spring sites move slower but spring break weeks fill quickly. Summer is wide open during the week and tight on weekends.
The campground sits adjacent to the fishing pier and within walking distance of the trail network. That makes it a functional base for a multi-day outdoor stay without needing a car for most of the day.
The America the Beautiful annual pass covers entrance fees at National Park Service sites (not relevant here since Davis Bayou is already free) but does not cover the per-night campsite reservation fee.
The Ship Island Ferry (from Gulfport)
West Ship Island is the most accessible of the barrier islands. The ferry to the island leaves from Gulfport Small Craft Harbor, not from Ocean Springs. The drive from Ocean Springs to the Gulfport ferry terminal is about 25 minutes west on Highway 90 or I-10.
Ferry season: Mid-March through end of October. The ferry does not run November through early March.
Crossing time: About one hour each way.
2026 ferry fares (Ship Island Excursions, the concession operator):
- Adult: $30
- Senior (62+) / Military / First Responder: $28
- Child 3-10: $20
- Children 2 and under: free
Summer schedule (May 16 - August 16, 7 days a week): 9 a.m. and noon departures from Gulfport; 2:30 p.m. and 5 p.m. return trips. Shoulder-season schedule is reduced to a single round-trip on weekdays. Book at msshipisland.com or call (228) 864-1014. Weekend and holiday tickets sell out — book at least two weeks ahead for summer and fall weekends.
Once on the island: the beach on the Gulf side is wide, white, and protected from the strongest current by the island’s location. Fort Massachusetts, a Civil War-era brick fort, sits at the west end of the island and is maintained by the Park Service. Ranger-led tours run during ferry season.
Bring everything for a full day: sunscreen, hat, water, food, beach chair. Concessions on the island are limited and not available outside peak season. Shade is scarce. The ferry schedule dictates how long you can stay (typically 4-5 hours on the island for the standard summer round-trip).
Horn Island and the Other Barrier Islands
Horn Island is the closest barrier island to Ocean Springs and the most storied. Walter Anderson rowed the 14 miles across the Mississippi Sound to Horn Island repeatedly over the last decades of his life, in a small wooden skiff loaded with art supplies, in all weather. The thousands of watercolors he produced there are the centerpiece of the Walter Anderson Museum’s collection.
The island itself is primitive and wild. There is no ferry service, no facilities, and no overnight accommodations beyond primitive camping. Getting there requires a private boat or a charter out of the Ocean Springs harbor. The crossing is exposed open water; this is not a day trip for the unprepared. Charter operators at the harbor will quote a half-day or full-day trip and bring you back the same day.
Petit Bois Island (further east) and Cat Island (west, off the Bay St. Louis coast) are also barrier islands within the seashore. Access is private-boat only. Both are undeveloped and require permits for overnight stays.
Park Hours, Fees, and What to Bring
Davis Bayou Visitor Center: 9 a.m. - 4:30 p.m. daily. Closed Thanksgiving, Christmas, and New Year’s Day.

What to bring for Davis Bayou: insect repellent with DEET (especially late spring and summer when biting flies are aggressive), water, binoculars if you bird, sunscreen for the pier and open spaces.
What to bring for West Ship Island: everything you need for an outdoor day on a remote beach. Sunscreen, hat, water bottles you can refill before boarding, packed lunch, beach chair, a dry bag for the ferry crossing if the chop is rough.
Hurricane season runs June 1 through November 30. Activity is heaviest August through October. Watch the National Hurricane Center forecast if you are camping during that window; the campground and ferry both close ahead of named storms.
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.
