On the other side of the valley and well hidden from the main crag at Taff's Well is a series of old quarried walls that contain some good sport climbs. The style varies from slabs to slightly overhanging featured walls and all the routes are technical. Although most of the walls apart fro the slabs are enclosed and shady, the climbing is well-worth searching out in the right conditions.
As for Taffs Well (East) to the roundabout below that crag, then turn left to Radyr, then right at next roundabout. 0.5mi further on the left is a blocked quarry track. Park in small housing estate on the right (gwaelod-Y-Garth, Heol Berry).
Take faint path up through woods to a good track: follow to small pinnacle with crag behind. Best to get there early to avoid parking problems. This is due to the fact that people leave there vehicles there while they go off to work. Does get very busy!!!!!
