St David's Head

St David's Head at the very tip of the Pembrokeshire peninsula juts into the full force of the Celtic Sea, creating tidal races and eddies that deliver exceptional visibility and concentrations of filter-feeding life across every rock surface. The headland's underwater topography is a complex arrangement of granite ridges, boulders, and gullies colonised by jewel anemones in vivid red, orange, and purple, making it one of the most photogenic cold-water sites in Wales. Encounter-driven diving here is reliable — grey seals, conger eels, and large schools of pollock and coalfish are present on virtually every dive throughout the year.
