Why it's Wildland

8.0

A former slate quarry flooded by the sea, its steep cut-stone sides now framing the vivid lagoon. Quarry remains and workers’ cottages recall the working landscape that preceded this coastal landmark.

A striking meeting of industrial history and rugged coast: the flooded quarry, sheer cliffs and remains of quarry buildings make this more than a scenic viewpoint. The short approach is memorable, but steep, uneven sections and exposed cliff edges call for care.
