Newton Bay (also known as Black Rock beach) is the most easterly of Porthcawl's beaches and is mostly sand with rocks towards Newton Point. The beach is backed by a sea wall and dunes, with Trecco Bay Holiday Park on the west side. The dunes and sandy beach extend eastwards towards Merthyr Mawr beach. Parking is at a P&D car park overlooking the beach, and free roadside parking can easily be found nearby. Access to the shore is down a slipway, and dogs are allowed at all times. This beach does not have lifeguards.
