About Dinorwic Slate Quarry (Vivian)

Dinorwic Slate Quarry (Vivian) is one of the most accessible and celebrated sectors in the Llanberis slate network, offering clean, slate slab and wall climbing around a deep flooded pit. The smooth, purple-grey slate is highly compact, relying on razor-sharp crimps, delicate wire placements, and subtle friction footholds. Facing east, Vivian catches early morning sun but falls into shadow by early afternoon, though its quick-drying slate surface sheds water rapidly after rainfall. The climbing spans low-grade sport routes to technical trad testpieces, with classics like Mental Asymmetry and Comes the Dog providing technical slab sequences. Access is straightforward, requiring a five-minute flat walk along tarmac tracks directly from the National Slate Museum car park in Padarn Country Park. Climbers should remain aware of potential loose slate fragments near top-outs and respect heritage railway safety fencing.
