Large former quarry, with single- and multi-pitch routes up to 73m. A few routes have loose rock and not much pro but those are the exceptions. Dries quickly. Best routes include Pine Tree (VD/S***) and Cowpoke (E1 5a).
From M4, J32, A 470, 0.5mi north. Overlooks S-bound carriageway of the A470 between Tongwynlais and Taffs Wells. Park at the base of the cliff where it meets the roundabout.
