Barataria Bayou to Grand Isle: Swamp Trails & Barrier Island

The Barataria Preserve protects 26,000 acres of the bottomland forest, cypress swamp, and freshwater marsh that constitutes the classic Mississippi Delta landscape. The Bayou Coquille Trail — a 2-mile circuit starting at the visitor center — passes through all three habitat types on a combination of upland trail and elevated boardwalk, crossing the bayou on wooden bridges and culminating at a marsh overlook where the transition from swamp forest to open water is dramatically apparent. Alligators are routinely visible from the boardwalk year-round; in spring, roseate spoonbills, great blue herons, and prothonotary warblers add vivid color to the cypress canopy.

The 2.8-mile Plantation Trail traces the ridgeline of a natural levee above the surrounding swamp — a micro-topographic feature elevated just 3-4 feet above the wetland that allowed the sugar plantations of the Barataria to exist at all. The trail passes through dense bottomland hardwood forest of live oak, hackberry, and palmetto before connecting to a marsh overlook boardwalk where the flat horizon of the freshwater marsh extends to the treeline. This is some of the most biodiverse terrain within an hour's drive of New Orleans.

Pack provisions from New Orleans — Rouses Market on Magazine Street is a good source for po-boy supplies, fruit, and cold drinks — and lunch at the preserve's picnic tables near the visitor center. No food is available on site.

The network of bayous threading the Barataria Preserve is best experienced from the water — the NPS offers ranger-led canoe tours seasonally, and year-round outfitters including Louisiana Lost Land Tours operate guided kayak trips through the preserve's inner channels. The cypress-tupelo canopy meets overhead in the narrower bayous, blocking the sky and creating a cathedral-like passage through the swamp; alligators rest on fallen logs at the waterline, and the only sounds are paddle strokes and bird calls. Reserve in advance for ranger-led tours; private outfitter tours typically require same-week booking.

Grand Isle is Louisiana's last inhabited barrier island — a 7-mile strip of sand and marsh at the end of Louisiana Highway 1, the most southerly road in the eastern United States. The state park at the island's eastern tip encompasses the beach, a restored barrier marsh, and the only significant migratory bird concentration site on the Louisiana Gulf Coast: during spring migration (April-May), exhausted neotropical birds arrive from their Trans-Gulf flight and drop into the island's live oaks and marsh edges in spectacular numbers — painted buntings, warblers, tanagers, and orioles in densities rare anywhere in North America. The early morning beach walk in migration season is extraordinary.

Fort Livingston, built on Little Cheniere (Cheniere Caminada) Island across Barataria Pass from Grand Isle between 1841 and 1861, was a federal defensive fortification intended to guard the Barataria Bay entrance to New Orleans. Never fully completed, the fort was seized by Confederate forces in January 1862 and abandoned later that year after Union naval operations made its position untenable. The brick walls, bastions, and gun emplacements now stand in dramatic ruin amid sea oats and storm-blasted live oaks, visible from Grand Isle across the pass and reachable by a 15-minute kayak crossing. Local outfitters on Grand Isle rent kayaks and provide the crossing route.

Grand Isle's south-facing Gulf beach — a narrow but genuine strip of sand on the Louisiana coast, the only publicly accessible barrier island beach in the state. The water is warm from May through October; the fishing pier at the state park's eastern tip extends far into the Gulf and attracts serious recreational anglers casting for red drum, speckled trout, and flounder. The afternoon light over the Gulf on the drive back to New Orleans is spectacular.
