A ferry day trip plus a boat-in wilderness camp, from the Mississippi coast.
For a 3-day weekend at Gulf Islands National Seashore, base your logistics out of Gulfport or Biloxi, Mississippi. Day one is an easy passenger-ferry day trip to West Ship Island for historic Fort Massachusetts and a swim, then days two and three are a true boat-in primitive beach camp on the Horn Island Wilderness.
One important logistics note the guidebooks often get wrong: West Ship Island is day-use only, open sunrise to sunset, so no overnight camping is allowed there. Primitive backcountry camping in the Mississippi unit is on the wilderness islands, Horn and Petit Bois, which are reachable only by private or charter boat, not by the public ferry.
No permit is needed to camp for groups of fewer than 10; groups of 10 or more must obtain a free wilderness permit from the park. April–May and September–October are the best months, with milder heat, lower humidity, and reduced hurricane risk. There is no potable water and no campfires allowed on the islands, so pack all your water and a stove.
Book the Ship Island Excursions ferry from Gulfport 2–4 weeks ahead for weekend trips (mid-March through October only). Horn Island has no ferry, so arrange a private charter or bring your own boat/kayak, and confirm a return pickup. The park entrance fee is $25 per vehicle (waived with an America the Beautiful pass). Camping is free for groups under 10; groups of 10 or more need a free wilderness permit, call the park at 228-230-4100.
Ferry to West Ship Island & Fort Massachusetts
Your weekend begins with the Ship Island Excursions ferry from Gulfport, a scenic roughly one-hour crossing of the Mississippi Sound with a good chance of dolphins alongside the boat. West Ship Island is the only barrier island in the Mississippi unit reachable by public ferry, and it runs mid-March through October.
On arrival, explore Fort Massachusetts, a brick Third System fortification completed in 1866, then spend the afternoon on the clear, white-sand Gulf beach. Because West Ship Island is day-use only, catch the return ferry and spend the night in Gulfport or Biloxi before your boat-in camp tomorrow.

West Ship beachDolphins on the crossingCharter to the Horn Island Wilderness & Primitive Camp
Primitive beach campSound wildlifeFrom a Biloxi or Ocean Springs harbor, take a private charter or your own boat/kayak roughly 10–12 miles offshore to the Horn Island Wilderness. Horn is a long, thin barrier island of white-sand beaches, sea-oat dunes, pine groves, and a few inland lagoons, one of the wildest, most undeveloped shores on the Gulf.
Land, then choose a primitive campsite on the open beach, above the high-tide line and off the dunes and vegetation. Spend the afternoon walking the Gulf-facing beach and watching for shorebirds and ospreys, then set up for a night of dark-sky stargazing with no light pollution. Pack all water and a stove, there is no potable water and no campfires allowed.

Essential barrier-island rules & planning.
Everything is boat access
West Ship Island is reached by the Ship Island Excursions passenger ferry from Gulfport (mid-March through October). Horn and Petit Bois have no ferry, they require a private boat, kayak, or charter. Confirm a return pickup and watch the marine forecast before heading offshore.
Leave No Trace, it is a wilderness
Horn and Petit Bois are designated wilderness. Pack out all trash and food scraps, bury human waste 6–8 inches deep and 200 feet from water and campsites, and camp on open beach above the high-tide line, never in the dunes or vegetation.
No water, no fires
There is no potable water on the primitive islands, so bring at least one gallon per person per day. Open campfires are prohibited; use a portable stove for cooking and store food securely to deter raccoons.
Insects & sun are serious
Mosquitoes, sand flies, and biting insects can be brutal at dawn, dusk, and after rain. Bring strong DEET or picaridin repellent, long sleeves, and a head net, plus sunscreen, a wide-brim hat, and shade, the beaches are exposed.
Permits & group size
Camping is free and needs no permit for groups of fewer than 10. Groups of 10 or more must obtain a free wilderness permit, call the park at 228-230-4100. The park entrance fee is $25 per vehicle, waived with an America the Beautiful pass.
When to go & getting there
April–May and September–October have the mildest heat, lowest humidity, and reduced hurricane risk. Summer is hot, humid, and stormy; winter is cool, windy, and ferry service is limited. Gulfport-Biloxi International Airport (GPT) is 15–20 minutes from the Gulfport ferry harbor.
