The key landscape characteristics of this section of Cornwall National Landscape are the variety of coastal scenery due to the diverse geology including hard greenstones, which form the elevated headlands as seen at Trevose Head and Stepper Point. The more easily eroded slates and shales back the bays and coves between the headlands as can be seen at Harlyn Bay, Trevone, Treyarnon and Mother Ivey’s Bay. There are extensive coastal sand dunes at Constantine Bay.
