The ferry from Gulfport cuts a steady line through the Sound, past channel markers and fishing boats, until Ship Island's low profile materializes on the horizon. You disembark onto a shore where Civil War ghosts and hurricane memory share the same sand—Katrina split this barrier island in two in 2005, though it has since reconnected. The south-facing beach rolls out in a ribbon of white so bright you'll squint even through sunglasses, backed by scrubby dunes and sea oats that hiss in the wind.
“This is the only Gulf Coast barrier island within Mississippi waters accessible by public ferry, where Civil War fortifications meet unguarded shoreline.”

Fort Massachusetts anchors the western end, its brick casemates offering cool shade and a reminder that this outpost once guarded Ship Channel. You'll wander through empty gun rooms where swallows nest, then return to the beach to stake your claim on sand that remains largely uncrowded even on summer weekends. The water here is shallow and bathwarm by July, stained the color of sweet tea by tannins from coastal marshes.
Pack everything in—there's a snack bar and restrooms, but no shade structures and no overnight stays. The last ferry departs mid-afternoon, so you'll watch the clock between swims. Oystercatchers patrol the tideline, their orange beaks probing for coquinas, while terns dive offshore. When the horn sounds, you'll board tired and salt-crusted, the mainland's green fringe growing clearer across the blue.
