In reply to Arms Cliff:
I might have to amend my wording there, as I was being a little unfair - not least because this is exactly the sort of place I'd love to go next time I'm down (and it does sound lovely).
On a similar note, we went for a nice family walk around the Marloes Peninsula when we were down in Pembroke last year. We didn't get a chance to do any of the bouldering at Marloes Sands, but would definitely go back because of how good the beach was. From a family perspective it's hard to beat a nice beach that just so happens to have some bouldering on it. Fun for all the family
