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.
