North Carolina's Coastal Plain is low, flat land along the Atlantic Ocean. It is often divided into two parts - the Outer Coastal Plain and the Inner Coastal Plain.

The Outer Coastal Plain is made up of the Outer Banks and the Tidewater region. The Outer Banks are a string of barrier islands separated from the mainland by sounds or inlets. The largest islands in the Outer Banks are Bodie, Hatteras, Ocracoke, Portsmouth, and the Core Banks. Three capes are part of the Outer Banks: Cape Hatteras, Cape Lookout, and Cape Fear. Near these capes are dangerous shoals, or underwater sandbars which are hazards to ships. Cape Hatteras is known as the Graveyard of the Atlantic because shifting sand has caused many ships to run aground. The Outer Banks stretch more than 175 miles along the coast.

The Tidewater is the area along the coast close to sea level. The mouths of the major streams and rivers empty into sounds or the ocean. There are seven sounds in the Tidewater region: Pamlico, Albemarle, Currituck, Croatan, Roanoke, Core, and Bogue Sounds. This region has many low-lying areas called wetlands, where water covers the land. The Great Dismal Swamp, a series of swamps scattered from Virginia, to North Carolina, South Carolina, and Georgia, is North Carolina's largest wetland area. It covers about 750 square miles, making it one of the largest swamps in the United Swamps. The Tidewater is the only place in the world where the Venus Flytrap plant grows naturally.

The Inner Coastal Plain, a higher, drier area, begins west of the Tidewater. The rich, sandy soil here is some of the state's best farmland. In the southwestern corner of the Inner Coastal Plain are the Sandhills, a subregion of rolling, sandy hills. This area has the highest elevation on the Coastal Plain, ranging from about 900 to 1,000 feet above sea level. Longleaf pines are native to this area.

Is their anyway I can get more information on the economy of the Inner Coastal Plain?


Dear Macy,

Thank you for visiting NCpedia and sharing your question. I am connecting you via email with Reference Services at the NC Government & Heritage Library.  A librarian will contact you shortly to help you locate more information.

Best wishes,

Kelly Agan


Are the Sandhills in the inner costal plain a natural resource?


Hi Carsyn,

The Sandhills are considered to be a separate geologic area that sits between the Piedemont and the coastal plains region.  They are considered a region composed of very ancient sand dunes that divide the two surrounding regions.

I hope this helps! Please feel free to post back if you have additional questions.

What Industrys are in the tide water region?


Hi Maddie,

Thank you for visiting NCpedia! You may be able to find information about different industries in the Coastal Plain region by looking at our county articles. You can find links to all 100 counties in our article about North Carolina counties. On the map, the counties in the Coastal Plain are in blue. The Tidewater region in the Coastal Plain will include the counties that are just on the edge of the state, closest to the ocean.

I am also forwarding your question to reference services at the NC Government and Heritage Library, using the email address you provided in your comment. A librarian will contact you shortly to help with your research if you are still looking for information.

Good luck with your research!

Laurie Reeves, Government & Heritage Library
