Taff's Well is a roadside crag on the outskirts of Cardiff, close to the M4 corridor. It consists of some big calcite walls mixed with areas of compact grey limestone. The climbs vary in style from short intricate face climbs through to longer routes - up to 35m in some cases - full of atmosphere and technical difficulties. Two other small crags close by have some less intimidating lower-grade lines and are further from the road and consequently quieter.
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.
