About this beach
Measuring approximately 900m in length, the bay is sandy, backed by an extensive dune system, with limestone cliffs on either side. Situated on the south west coast of Anglesey, the bay is considered to be fairly remote, due to its 1 kilometre proximity from the nearest road way. The dune system is protected and listed as a Special Area of Conservation, with the beach area making up part of the Tywyn to Aberffraw Site of Special Scientific Interest, confirming the high conservation status of the Area. The site also lies within the Anglesey Area of Outstanding Natural Beauty. The water quality sample point lies at the north end of the beach, 150 metres south of the cliffs.
