About this beach
The beach is gently sloping and made up of sand and pebble. On a low tide, ancient peat beds are exposed on the west side of the bay, near to the boat lane. The beach is backed by the village of Port Eynon, with a car park in the immediate vicinity and sand dunes stretching east to Horton. The headlands form part of a Site of Special Scientific Interest, whilst the bay area makes up part of the Carmarthenshire Estuary Special Area of Conservation. The designated sample point is located opposite the roundabout, at the western end of the Bay.
