The easiest access is from the village of Llanllawen (Grid Ref: SH147258 / Lat : 52.7984°N, Lon : 4.7489°W) from where a footpath leads ½ mile across fields and down into the valley behind the beach.
Porthorion (Grid Ref : SH156288) lies to the north, and is a small cove of rocks and pebbles backed by grassy slopes. A public footpath leads from the road at nearby Capel Carmel.
