About this beach
<p>Measuring approximately 350 metres wide, facing north into the Irish Sea, Cemaes is an enclosed sandy bay, backed by a promenade. There is a concrete jetty in the southwest corner of the bay, which provides a small harbour for leisure craft and some inshore fishing vessels. The water quality sample point is located opposite the car park, approximately 50 metres east of the harbour. The beach lies within the Anglesey Area of Outstanding Natural Beauty and part of the beach is within the North Anglesey Heritage Coast.</p>
