Porthlysgi Bay (pronounced 'porth lissgy') is a peaceful beach a few miles west of St Davids. The beach is sandy at low tide with a pebble bank and looks out to the small craggy islet of Carreg yr Esgob (Bishop Rock) just offshore. A small cove just to the east can be reached by walking over the rocks, or wading at low tide. The shore has a rich variety of pebbles, including sandstones of various colours, mudstones and quartz pebbles.
Access is from the coast path which runs for a few yards along the back of the beach. The nearest parking is an attended car park at Porthclais (where teas and ice-creams are available) at Grid Ref: SM739242 (Lat : 51.8707°N, Lon : 5.2854°W). From here you can take the coast path westwards but a shorter route is to follow the track which begins opposite the car park and joins the coast path near to Porthlysgi Farm. Being very sheltered, it's a good beach for sunbathing and swimming. There are no facilities here.
