About this beach
Measuring just over 100 metres in width, with interbedded mudstone and sandstone cliffs on either side, the sandy, sheltered beach has a distinctive large rock on the shore’s edge. The coastal waters and coastal belt are designated as the Cardigan Bay Special Area of Conservation and the Aberarth Cerreg Wylan Site of Special Scientific Interest, confirming the high conservation status of the area. A small unnamed stream and the Nant Hawen enter the sea at Llangrannog Bay, both of which drain agricultural land. The water quality sample point is located to the centre of the beach.
