The Palisades, also called the New Jersey Palisades or the Hudson Palisades are a line of steep cliffs along the west side of the lower Hudson River in northeastern New Jersey and southern New York in the United States. The cliffs stretch north from Jersey City approximately 20 mi (32 km) to near Nyack, New York. They rise nearly vertically from near the edge of the river, approximately 300 feet at Weehawken and increasing gradually in height to 540 feet near their northern terminus. From Fort Lee north the Palisades are part of Palisades Interstate Park and are a National Natural Landmark.
