About this beach
The bay faces south towards the Bristol Channel and is approximately 650 metres, at its widest point, with limestone cliffs on either side. Sand slopes gently to the sea, fringed by a shingle bank, at the high tide mark. A caravan park backs on to the Bay. The water quality sample point is located at the centre of the beach.
