Porth yr Ogof is a tranquil cove of shingle and some sand just to the north of Wylfa power station. On the north side is a small tidal island (Ynys yr Wyn) and the concrete remains of a slipway from a former lifeboat station. Parking is at a small free car park at the end of the road from Tregele (Grid Ref: SH356937). There is an information board, picnic table and cycle stands here. From the car park entrance, a public footpath leads into a wooded area where it divides: the path on the left leading to the coastal path behind the beach and the path on the right leading to nearby Porth Wylfa. Final access to the shore is down a short steep path with steps.
The photos were taken at mid-tide, and show the beach deserted on a hot July afternoon.
