In my school days I was a regular at what we then called Shell Bay. We used to go fishing off the platform where the headland juts out in to the sea to the right of the beach but, particularly if the weather was bad, we used to go inside the quarry buildings which have now vanished along with most of the gun emplacements long gone in to the sea.Erosion there has been severe in the last 50 years and the cliff edge must be 30 metres back in some places where there is nothing but soil to hold back the sea.
It's an interesting place to go, much more compact than the Great Orme and if anything I prefer to wander there with my camera looking for wildlife shots.
