Visitors to Hatteras and Ocracoke Islands will simultaneously be visiting the gorgeous Cape Hatteras National Seashore. One of the largest preserved parcels of the Outer Banks, the National Seashore stretches across 70 miles of shoreline, encompassing seven villages on Hatteras Island, and providing visitors with miles of undisturbed, scenic beaches as well as some of the prettiest natural drives on the East Coast.
