The limestone crags of Clwyd are situated on the escarpment above Llangollen. UK Climbing says of Pinfold Crag in Llangollen, ‘A magnificent group of crags offering the visitor a great variety of climbing in all grades. Wall climbing, jamming cracks sport routes, lunatic fringe routes, and even some aid can all be had here.’ There is also a gritstone quarry at the far end of the escarpment, often used by groups.
