Site Description: A mixture of sharply ridged sandstone ridges and boulder areas between an extensive intertidal with a mixture of exposures, sheltered in the boulder areas and moderate on the rock ridges. The shore is backed by glacial deposited shingle with grasslands behind. It is situated on a headland on the open coast adjacent to a small sandy bay with similar ridges to the south. The upper shore ridges are smaller and more brittle whereas the lower shore ridges are large with steep sides. Boulders occur between the ridges especially in the middle shore. The shore is fucoid dominated with patellobarnacle in the more exposed areas. The upper shore has an extensive supralittoral lichen zone.
