The Anglesey Coast Path cuts across the neck of the Penrhyn headland by-passing these two beaches, but coast path walkers aren't missing much. Backed by farmland, both beaches are mostly coarse grey sand and shingle, with seaweed-strewn sand lower down.
Porth Delysg (above) is about 400 yards wide, and bounded on the northern side by the Penrhyn Bay Holiday Park - a path from here leading onto the shore.
Porth Dryw is about 200 yards wide and access is along the shore from either end. A small stream emerges onto the beach via a culvert.
The photos were taken at mid-tide.
