It is roughly coterminous with Cape May County and runs southwards from the New Jersey mainland, separating Delaware Bay from the Atlantic Ocean. The southernmost point in both New Jersey and the northeastern United States lies on the cape. A number of resort communities line the Atlantic side of the cape, including Ocean City, the most populous community on the cape, The Wildwoods, known for its architecturally significant hotel district, and the city of Cape May, which has served as a resort community since the mid-1700s, making it the oldest such resort in the U.S.
