Aberporth is situated between the headlands of Trecregyn and Fathgarreg, and has two bays, which at high tide are separated by a rocky headland. Dolwen is the western bay and the most popular for swimming and sunbathing. The other (Dyffryn) has a slipway and a substantial stream (Nant Howni) flowing along its eastern side. Both beaches are sandy with plenty of rock-pools. The headland to the west of the village is occupied by the MoD research base, and access to Cribach Bay (which lies beneath it) is not possible either from the land or along the shore. Eastwards from Aberporth, a few rocky coves can be reached from the coastal path.
A small car park is just above the beach and further car parking is available in the village. Facilities include toilets, cafes and pubs. Lifeguards patrol in summer and a dog ban operates on Dolwen beach from 1st May to 30th September.
Surf conditions are best around low to mid tide with south-west winds and a big swell. Being sheltered it's worth a try when other beaches are blown out and is generally suitable for beginners.
