Morfa Mawr is a beach of sand, rocks, small streams and rock-pools. It's backed by low cliffs of boulder clay which are suffering badly from erosion. To the south, the banks rise steeply to the black shale cliffs of Graig Ddu, where the remains of fish traps can be seen at low tide. Access is from the A487 - a public footpath leads through Morfa Mawr farm to the coastal path behind the beach. Alternatively, take the coastal path from Llanon. Dogs are allowed at all times.
