In 1978 Congress designated Petit Bois and Horn Island - among the few undeveloped barrier islands 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.
