Castle Inn Quarry is a highly popular, sheltered limestone sport and trad venue located roadside at Llanddulas near Colwyn Bay. The quarried Carboniferous limestone features clean vertical walls, sharp crimps, and well-defined crack systems. Facing north at low altitude, the crag stays in shade but sits in a prominent rain shadow, drying almost instantly after rainfall. Grade options are exceptionally diverse, offering accessible French grade 4 sport climbs up to technical 7s and trad testpieces. Classics like Route 1 provide ideal warm-ups or coaching terrain on reliable rock. The approach takes under two minutes from the roadside parking layby opposite the pub. Traffic noise from the adjacent A55 expressway is constant.
