Blaengwynlais Quarry is located between the town of Caerphilly (just under a mile to the north) and the outskirts of the city of Cardiff (just over a mile to the south). It is situated on the eastern side of Rhiwbina Hill, and extends across the county boundary with Caerphilly. The majority of unworked reserves fall within Caerphilly’s administrative area, although the access and processing areas lie within Cardiff. The quarry is currently inactive and is classified as “dormant” rather than abandoned. Beware of old air shafts in the woods and meadows to the north. The locality is known for its goethite iron ores which outcrop in rusty orange and brown pyrite crystals in a rich variety of shapes from needles to concentric blobs.
