Picturesque site of former 'holy well' dedicated to the sixth-century saint, Cybi. Two stone well-chambers and a later cottage survive.
This beach’s dramatic English name is based not just on its semicircular shape resembling a wide, open mouth. Its hellish dimension comes from a savage, south-westerly aspect that offers precious little shelter to sailors.
