Directions
National Seashore Units
Gulf Islands National Seashore encompasses six separate units in Florida. In Mississippi, there is one coastal unit – Davis Bayou – and six barrier islands within the National Park.
Of these, West Ship Island and Horn Island are the most popular destinations.
Most of the barrier islands of Gulf Islands National Seashore in Mississippi can only be reached by private boaters and paddlers, providing unique wilderness camping experiences.
Ship Island can be visited by using an official tour boat out of Gulfport.
Full details on major units within Florida are provided on separate pages. Additional units include Okaloosa on Okaloosa Island along Choctawhatchee Bay and the Santa Rosa Area (which includes Opal Beach) on Santa Rosa Island.
Fort Barrancas Part of the Third System of coastal defenses built in the 1840s by the Army Corps of Engineers, Fort Barrancas is the showy centerpiece of a National Park unit inside Naval Air Station Pensacola.
Fort Pickens With more than seven miles of beaches along Santa Rosa Island, the Fort Pickens Unit at Gulf Islands National Seashore is a compelling destination at Pensacola Beach.
Johnson Beach As part of Gulf Islands National Seashore, the windswept tip of Perdido Key goes on for miles at Johnson Beach. Discover natural habitats and wild shores along its length.
Naval Live Oaks Area Spanning from Santa Rosa Sound to Pensacola Bay, Naval Live Oaks Area is one of America's oldest federally protected forests, now part of Gulf Islands National Seashore.History
Coastal Defenses on the Gulf Coast
Fort Barrancas
To defend the entrance to Pensacola Bay, the British Royal Navy constructed a log-and-earth redoubt on high ground facing the inlet in 1763. After the American Revolution, the Spanish took the high ground and added a water battery in 1797.
Florida became a territory in 1821. With Pensacola chosen as the site of a Federal naval yard, the United States Navy has held this strategic ground since.
Part of the Third System of coastal defenses built by the Army Corps of Engineers, the brick behemoth atop the bluff today was completed in 1844 under the supervision of Major William H. Chase.
Although it is part of Gulf Islands National Seashore, it is at the core of Naval Air Station Pensacola and you must go through a checkpoint at the West Gate on Blue Angel Parkway to visit Fort Barrancas and its Advanced Redoubt.
The two are connected by the Trench Trail, a 1.1 mile round trip on a natural surface walk in the woods.
Advanced Redoubt
The Advanced Redoubt of Fort Barrancas was built between 1845 and 1859 to protect both Fort Barrancas and the Pensacola Naval Yard but was never used.
Fort McRee
Fort McRee on Perdido Key dated back to 1834, with 128 cannons trained on the entrance to Pensacola Bay.
It succumbed to erosion by wind and waves over more than a century, so there is nothing left to interpret of Fort McRee. Only boaters and divers can see what’s left of its bricks and a 1942 battery. Most of it lies at the bottom of in Pensacola Bay.
Fort Pickens
Of the forts now protected and interpreted at Gulf Islands National Seashore, Fort Pickens on Santa Rosa Island has the most storied history. Construction of Fort Pickens began in 1829 under supervision of the Army Corps of Engineers.
When it seemed America would slip into war, President Abraham Lincoln sent Federal troops to occupy Fort Pickens. On November 22, 1861, these troops shot more than 5,000 cannonballs from Fort Pickens into Pensacola. Confederate leaders retreated and burned the city.
Fort Pickens continued in use through World War II, sometimes as a military prison. In 1886 the Apache chief Geronimo was imprisoned at the fort as a tourist attraction.
For World War I defenses, concrete gun batteries were added at strategic points along Santa Rosa Island and atop the existing brick fortress itself. The military decommissioned Fort Pickens in 1949.
Fort Massachusetts
In Mississippi, West Ship Island is topped with the westernmost of these coastal defenses, Fort Massachusetts. Built after the War of 1812 in response to the British attack on New Orleans, it remained in service through 1903.
Hiking at Gulf Islands National Seashore
Nature Trails
Short nature trails at several National Seashore units let you sample coastal habitats.
In Florida, these include the Fort Pickens Trail and Blackbird Marsh Trail at the Fort Pickens Unit.
In Gulf Breeze, explore the Brackenridge Trail and the Jackson Trail network at Naval Live Oaks Area.
West of downtown Pensacola, ramble the Trench Trail and the Woodland Trail at Fort Barrancas, and the Perdido Key Discovery Trail at Johnson Beach.
In Ocean Springs, Mississippi, Davis Bayou offers several short interpretive trails, including one that starts right at the Visitor Center.
With the exception of the Andrew Jackson Trail and its connected series of trails on the north side of Naval Live Oaks – which at an estimated 6 miles of trails, is long enough for a substantial day hike – all nature trails in Gulf Islands National Seashore are easy interpretive trails. Some are accessible.
Perdido Key Discovery Trail Showcasing the habitat diversity of Perdido Key at Johnson Beach, the accessible Perdido Key Discovery Trail is a gentle boardwalk over wetlands, forests, and dunes.The Florida Trail at Gulf Islands National Seashore
The Florida Trail crosses Gulf Islands National Seashore east-west on Santa Rosa Island, providing one of the few places in America where you can walk a National Scenic Trail along the beach.
There are few blazes, but the entrance and exit points to the Santa Rosa Area and Fort Pickens segments have signage. Camping is not permitted along the beach, but hikers can arrange a tent site at Fort Pickens Campground with advance reservations.
At Fort Pickens, you’ll find the Northern Terminus of the statewide Florida Trail. A marker commemorates this along the Fort Pickens Trail, to the east of the fort itself.
Florida Trail, Fort Pickens 6.9 miles. At the westernmost tip of Santa Rosa Island, the Florida Trail comes to its Northern Terminus in the shadow of the most important historic sites in Northwest Florida, Fort Pickens.Bicycling at Gulf Islands National Seashore
Cyclists are permitted to ride the entire length of the Florida Trail on Santa Rosa Island with the exception of the UWF/SRIA Dunes Preserve.
Fortunately, the Pensacola Beach Bike Path starts right where that part of the trail diverges to Santa Rosa Sound.
Florida Trail, Seashore In addition to bike paths and the scenic UWF-SRIA Dunes Preserve, the 32-mile Seashore section of the Florida Trail walks you along a beach to the trail's Northern Terminus. At Davis Bayou in Mississippi, a paved bike path, the Live Oak Bicycle Route, connects the community of Ocean Springs with the National Park.
Paddling at Gulf Islands National Seashore
Paddlers have plenty of places to play at Gulf Islands National Seashore, since it is a National Park on the coast. The primary use of the Okaloosa Island Unit on Choctawhatchee Bay, in fact, is windsurfing.
At the Naval Live Oaks Unit, kayak launch points are provided both on Santa Rosa Sound near the Headquarters Building and on Pensacola Bay near the group campsite.
At Fort Pickens, look for a launch point into Pensacola Bay from the parking area adjoining Battery Worth. A boat ramp at Johnson Beach adjoins the Perdido Key Discovery Trail and serves as a launch.
For long distance paddlers, Fort Pickens is along Section 1 of of the Florida Circumnavigational Saltwater Paddling Trail, which starts to its west at Big Lagoon State Park across from Johnson Beach and involves a paddle across the open waters of Pensacola Bay
In Mississippi, Davis Bayou has a launch right by the visitor center at the fishing pier, and a boat launch farther along the park road.
Sea kayakers have the big advantage along this portion of the Gulf Coast, as they can paddle between all the barrier islands from Pascagoula to Gulfport, and camp on them. No facilities or water are provided.
Camping at Gulf Islands National Seashore
In Florida, Fort Pickens Campground is the only campground in Gulf Islands National Seashore.
It has five loops containing 211 campsites. Loop B, with 13 sites, sits along the Florida Trail and is reserved for tent camping.
There are quite a few bathhouses scattered around the campground complex, which is large enough to get lost in.
Most campers bring bicycles to get around. While some of the loop areas offer shaded spots, most sites are in the full sun.
Set in a coastal forest, Davis Bayou Campground in Mississippi has 52 sites, with three specifically reserved for tent camping.
Electrical hookups, potable water, and a dump station are provided along with a bathhouse.
Backcountry Camping
The only backcountry camping in the Florida units of Gulf Islands National Seashore is at the Naval Live Oaks Area.
Scouting groups and other organized youth groups may reserve the group campsite, which provides access to Pensacola Bay for paddling and the Jackson Trail for hiking.
This is a tent camping site but you can drive within a close distance of it. Restrooms with flush toilets and a covered picnic shelter are provided. When the camping area is not in use, it is open to the public as a day use area off US 98.
Kayakers and boaters may camp on certain barrier islands within Gulf Islands National Seashore on the Mississippi Gulf Coast. These include Horn Island, East Ship Island, Sand Island, and Petit Bois Island.
No permits or reservations required, but it’s smart to let the rangers know you are headed out there. These are wilderness areas.
You are responsible for your well-being. There are no facilities, including no potable water. Pack out all trash.
