The Y Gyrn Ring Cairn is a Bronze Age monument situated under the black cliffs of Y Gyrn overlooking Portmeirion and the estuary of Afon Dwyryd. It is close to the footpath from Caerwych Farm to the beautiful Bryn Cader Faner.

The 2 metres wide ring of stones forms a circle 12 metres in diameter.

A burnt mound and another cairn with a large exposed cist straddle the footpath 90 metres to the south east of the ring cairn.
