Dinorwic Slate Quarry (Australia Quarry) sits on a prominent high level of the slate workings, offering vast, open walls of dark slate under the skyline of Elidir Fawr. The rock character features clean, vertical slate walls, sharp micro-edges, and geometric groove systems with a mix of trad and bolted protection. Boasting an open southerly aspect, the quarry acts as a natural sun trap and dries almost immediately once rain clears. The climbing ranges from upper 6th grade sport climbs to formidable E-grade trad lines, exemplified by famous routes like The Mau Mau and Loonin' Shore. The approach demands a thirty-minute steep trek up old incline pathways and tramways from Marchlyn or the main Dinorwic tracks. Navigating old quarry workings and scree slopes requires sturdy footwear and care near unstable upper edges.
