Cefn Cyfarwydd

Cefn Cyfarwydd is a ridge in Conwy county borough, north Wales. It is located above the village of Trefriw on the western side of the Conwy valley, and dramatically separates the rugged mountains of the Carneddau from the greener, lusher Conwy valley.

The Welsh word cyfarwydd can mean either "familiar" (adj.) or "a story-teller, guide or expert" (noun). Cefn means "ridge".
'Cefn Cyfarwydd' therefore translates as either "familiar ridge" or "story-teller's ridge".
