Carmel Head

Carmel Head is a prominent coastal headland on the north-west tip of the island of Anglesey.

It is a designated SSSI because of its geological interest for the Carmel Head Thrust fault where Precambrian rocks have been pushed over younger Ordovician rocks creating the Carmel Head thrust. Rock exposures along the cliffs of Carmel Head include Precambrian gneisses, which are almost certainly the oldest rocks in Wales.
