About Castle Inn Quarry

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.

Region: North Wales — Colwyn Bay
