Aberporth beach is situated between the headlands of Trecregyn and Fathgarreg. It has two bays, which are separated by a rocky headland at high tide. The southern beach (Dolwen) is the most popular for sunbathing. The northern beach (Dyffryn) has a large stream flowing across it, and a slipway for launching boats. Both beaches consist of coarse sand with plenty of rockpools. The headland to the west of the village is occupied by the MoD research base, and access to Cribach Bay (which lies below it) is not possible either from the land or along the shore. To the east are a few rocky coves with some caves which can be reached from the coast path. The cliffs here are mostly slates and shales.
Car parks are located above the beach and further car parking is available in the village. Lifeguards patrol from late June until early September 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 good for beginners. Facilities here include toilets, cafes and a few pubs.
