The bedrock was very flat to the west of the beach. Smooth pits had formed in the bedrock to become rockpools, especially in the lower shore. There were also boulders in the mid to upper shore. Beyond the flat bedrock lay an area of sloping bedrock with boulders, rockpools and gullies. The characterising species of the area were barnacles (Chthamalus and Semibalanus balanoides), limpets (mainly Patella vulgata), topshells, periwinkles, fucoids (Fucus spiralis, Fucus vesiculosus, Fucus serratus) and laminarians.

The metamorphic bedrock is in layers, each of which is angled up, away from the sea. Some layers are at angles of up to 60 degrees, providing a series of ridges. The sheltered sides of these ridges have many fissures and cracks, whilst the exposed, seaward sides are flatter and, in the main, dominated by barnacle cover (Chthamalus sp.). The majority of species were found on the leeward side of the ridges, in crevices and rockpools. There was frequently sand in the base of the shelterd pools, whereas those on the exposed sides contained no sediment. Those slopes on the seaward sides displayed exposed shore characteristics with a few brown, green and red algae:-coralline growths being the most noticeable of the algae present (Corallina spp., Lithothamnian/Lithophyllum spp.). The rockpools were rich in diversity, showing large densities of red algae. Chthamalus was the main species, covering most areas, except the rockpools and lee crevices.
