Good temperature for mountain rhyolite

Craig y Clipiau is a sunny slate and volcanic hybrid crag situated near the Crimea Pass above Blaenau Ffestiniog. The rock features a combination of compact slate-like slabs, sharp volcanic ridges, and well-defined crack lines. Facing due south at mid-altitude, the cliff acts as a natural sun trap and dries very quickly following weather fronts. The climbing spans Severe to hard E-grades, offering sustained wall climbs, jam cracks, and delicate slab sequences like Gargantua. The approach takes under fifteen minutes up a gentle hillside track from the main A470 mountain pass laybys. Cold winds across the high mountain pass can feel bitter despite full sun exposure.
