Deer Island is an uninhabited barrier island off Biloxi, Mississippi, offering pristine shoreline, abundant wildlife, and serene paddling waters.
Deer Island stretches roughly two miles along the Mississippi Sound, positioned close enough to the Biloxi waterfront to see the city skyline yet wild enough to feel genuinely remote. The island has been protected from development for decades, and that restraint shows in the density of its natural communities, from cordgrass marshes on the back side to open sandy beaches facing the Gulf.
Birdwatchers find the island especially rewarding. Brown pelicans, great blue herons, ospreys, and seasonal shorebirds use the island as resting and foraging habitat throughout the year. The surrounding waters are equally alive, with bottlenose dolphins a near-constant presence and schools of redfish and speckled trout drawing anglers into the sound. Joining a kayaking excursion from Biloxi is a practical way to reach the island with a guide who knows the tides and currents.
The broader Biloxi area adds context to any visit. A few miles west along the waterfront, the Golden Nugget Biloxi Hotel & Casino anchors the resort strip, and the region's seafood restaurants serve Gulf shrimp and oysters that reflect the same waters surrounding the island. For a longer Gulf adventure, Ship Island lies farther offshore and offers a ferry, historic fort, and open swimming beach. Deer Island itself remains the quieter, more intimate choice, and that simplicity is precisely what makes it worth the paddle out.
Visit during spring or fall for the most comfortable temperatures and the best wildlife sightings, including migratory shorebirds passing through the Mississippi Sound.
Arrive by kayak or paddleboard, as there is no ferry or public boat service to the island, making your own human-powered craft the most practical option.
Bring all food, water, and sunscreen, since Deer Island has no facilities, shade structures, or fresh water available on shore.
Launch from the Biloxi Small Craft Harbor for a manageable paddle across the sound, keeping an eye out for dolphins that frequently escort visitors.
Plan your visit around a rising tide so shallow sandbars near the island are easier to navigate and you have more beach to explore on arrival.
