OK I will go first, so be prepared for a long answer, because the park streches for over 160 miles (over 255 KM) along the northern coast of the Gulf of Mexico, stretching from Florida to Mississipi.
The U.S. National Park Service manages the Gulf Shores National Seashore, which is actually twelve seperate relatively small units or parks within one large system encompassing almost 500 square kilometers. http://www.nps.gov/guis
. The Seashore's heart and soul are the eight barrier islands with their sugar white sand beaches and the emerald color of the shallow water. The longest of of the islands is Santa Rosa Island, which is just over 74 kilometers in length, and has three of the twelve units. The most developed areas are the five units in and around Pensacola, Florida, where you can drive cars on paved roads to within 50 meters of the beach in some areas. The least developed areas are the five islands south of Mississippi, and are accessable only by boat.
Other attractions include the availability for close observation, of a wide variety of shore and water plants, birds, fish, mammals, reptiles, and two of the local favorites the sea turtle, and dolphins. A very interesting fact is that the islands are constantly moving from east to west sometimes a few inches a year sometimes hundreds of feet, and they are considered by some people to be a living thing. The barrier islands get their name from their location along the coast and the protection that they provide the mainland from storms especially hurricanes.
In summation the Gulf Shores National Seashore is a natural wonderland with something for almost everyone, and hopefully it will be around for generations to come.
