Cyfrwy Arete (Cader Idris) is a grand mountain ridge feature set on the northern precipices of Cader Idris in Mid Wales. Constructed from hard volcanic rock, the ridge offers superb multi-pitch scrambling and traditional climbing on rough, weathered blocks. Facing north high above Llyn y Gadair, the route sees minimal sunlight, keeping the rock cold and damp in shaded chimneys and gullies. The climbing is predominantly lower-grade trad and scrambling, with Cyfrwy Arete providing an iconic alpine-style excursion via the famous Table Tap. The approach takes a sustained sixty to seventy-five minute mountain hike up the Pony Path from Ty'n-y-groes. High altitude weather exposure and slippery grass top-outs require stout boots and alpine foresight.
