The private estate of Bodorgan (emphasis on the middle syllable) lies on the southern coast of Anglesey between the Afon Cefni estuary and the dune system of Tywyn Aberffraw. The Anglesey Coastal path takes an inland diversion around it, and there is no public access. The shoreline consists of a series of small, intimate sandy coves flanked by low cliffs and backed by dunes. Most beaches face south-west, but Porth y Ddinas, Porth y Ddraenen-wen (above) and Porth Cerig-cochion lie east of the Pen-y-parc headland and face south. The narrow inlet on the west side of Porth Twyn-mawr is known as Porth Cerig-Iago. Being inaccessible to the general public, these coves have been protected against commercialisation and caravan parks, and remain now much as they have been for hundreds of years.
The beaches from east (Malltraeth) to west (Aberffraw) are :
