The tiny cove of Porth yr Hwch (above) lies just south of Carmel Head at the top north-western corner of Anglesey. The shore is mostly pebbles and low-tide rock-pools, with a small stream tumbling down the high cliffs which back it. Access is possible by scrambling down a very steep grassy bank on the south side. Its name translates as Cove of the Sow.
Just around Carmel Head, Porth y Dyfn (Grid Ref : SH293929) is another tiny cove of rocks and pebbles which sits at the end of a small gully. A footpath from the coastal path leads down to it, and access is along the gully.
Note that this section of the coastal path is closed from 15th September until January 31st (inclusive) every year, and a diversion is in place through Mynachdu Farm.
