There is a Dingle Peninsular on Ireland's wild west coast. The little bay on the peninsular is where the Lt and woman meet in the movie of novel "The French Lieutenant's Woman."
However in next scene the beach has the Cliff's of Mohr in background which are further up the coast, north of Limerick. Movie magic.

The Dingle beach is beautiful, small,and you have to scramble down a steep rocky path to get to it. The surf has a nice left break which my son's surfed in 1971. Lost a full wet suit there...if anyone finds it washed up on the sands, keep it. They've outgrown it!
