Where's Blackrock sands Paul? I can't find it on my map.
I love Anglesey - must get back there again soon and re-visit the sites that were closed due to Foot and Mouth last time I was there.
Black rock sands is near Porthmadoc, on the Lleyn peninsula, not Anglesey. Apologies for the time you spent on a fruitless and pointless search!
I think I should have said Church Bay, which would put what I was looking for in the viscinity of Llanddeusant, or Cymyran bay, which means something near Capel Mawr.
