Porth-y-Pistyll (above) is a small shingle cove on Anglesey's north coast, just to the west of Wylfa power station. A footpath leads from the nearby lane at Grid Ref: SH348931 to a stone track where it meets the coastal path. Turn right here onto a grassy track, passing some ruins on the left. As this track approaches the shore look for a kissing gate on the left (which may be partly obstructed by gorse bushes). This leads onto the beach.
Porth y Felin (Grid Ref: SH343934) is ¼ mile to the west, and is a very similar beach of shingle. The coastal path between the two beaches passes over a clapper bridge next to Cestyll watermill.
The photos were taken 2½ hours after high tide. The name Porth-y-Pistyll translates as 'Cove of the spring' and Porth y Felin as 'Mill Cove'.
