Caerfai Bay near St Davids in Pembrokeshire, West Wales has cliffs of purple sandstone and a sandy beach at low tide reached by steep steps. The beach is situated in the Pembrokeshire Coast National Park and on the Pembrokeshire Coast Path and has rugged coastal scenery with the path winding up and down the cliffs. There is free parking above the beach with picnic benches and views of the islands of Penpleidiau, Skomer and Skokholm.


Caerfai beach is only 1.4 kilometres (0.87 mi) from centre of the cathedral city of St Davids. Along the coast to the west is the Chapel of St Non (51°52′20″N 5°16′08″W / 51.8722°N 5.2688°W / 51.8722; -5.2688 (Chapel of St Non, Pembrokeshire)) which is the most westerly in Wales. On the eastern headland are ramparts of the Iron Age fort of Castell Penpleidiau and Caer Bwdy is next bay to the east.

Penpleidiau Geological Map
Simplified geological map of Penpleidiau headland, Caerfai Bay.


Both western and eastern cliff sections display distinctive red, purple and greenish mudstone and sandstone formations representing the Caerfai and Porth-y-rhaw Groups of lower to middle Cambrian age. The southern tip of the eastern Penpleidiau headland and its small islets are composed of an Intrusive igneous rock known as felsite. the intrusion is in sharp contact with baked fossiliferous Middle Cambrian (Drumian) mudstones of the Menevia Formation and the Tomagnostus fissus Biozone of Scandinavian biostratigraphic terminology (Rees et al., op. cit.). There are disused quarries below the car park and at Caer Bwdy Bay which provided stone in the original construction of St Davids Cathedral and recent renovation on the structure.
