North East Wales



Area Map

North Wales has two main areas of Carboniferous Limestone. The first stretches from the Great Orme at Llandudno to Ruthin. There are several small caves on Great Orme's Head, but the main attraction here are the extensive copper workings, both Bronze Age and Victorian in age. There are several minor caves where the River Elwy valley crosses the limestone outcrop near Henllan.

The second area, separated by the fault bounded Vale of Clwyd stretches from Prestatyn on the coast to Oswestry. The majority of caves are found in this second area, particularly around the Alyn Valley and on Minera Mountain. Many of the caves are associated with lead mining.
