The cave has four entrances, the largest being that on the right measuring 8ft x 8ft. A mine adit (possibly prehistoric) within a natural cave follows a copper vein for 40m. Miners deads are cemented with flowstone and stalagmitic formation. In places are hammer-stone marks on ore-bearing rock.
Just above Marine drive a few yards east of the Hafnant dry valley.
