Porth Eilian Beach is a shingle and sheltered beach near the town of Amlwch, on the north east side of Anglesey, Wales. It stands between the rocky headland of Point Lynas and the inlet known as Porthyrychen near to the village of Llaneilian. It is popular for sailing, kayaking, snorkeling, diving due to its slipway. It is also a good place for wildlife watching, including oystercatchers, choughs, ravens, gannets, seals and porpoises. A preferred walk is along the coast from Point Lynas to Amlwch Port where copper was exported all over the world.
