Gulf Islands National Seashore invites you to #FindYourPark. The Seashore, with its blue-green, sparkling waters, magnificent white beaches, and fertile coastal marshes, is made up of 12 areas, including historic forts, shaded picnic areas, bayou and coastal view trails, campgrounds and island wilderness areas. From Cat Island, Miss., it stretches eastward 160 miles to the Okaloosa Area east of Fort Walton Beach.
