Visiting Wilderness Areas
In 1978 Congress designated Petit Bois and Horn Islands - among the few undeveloped barrier isalnds on the Gulf Coast - as wilderness areas. Uncommon species of birds, animals, and marine life are protected here. These areas also preserve the land's natural conditions and provide opportunities for solitude and primitive recreation; benefiting generations to come.
Before visiting Petit Bois and Horn Islands, ask a ranger about wilderness area regulations and the difficulties of visiting places without water, shelter, facilities, or communication. Park rangers can help you plan. Please practice Leave No Trace principles.
Horn Island is only accessible via private boat. If traveling in your private vessel consult navigational charts. To find an operator who can provide tours, fishing charters, or transportation, visit our Authorized Commercial Operators page below.
