Llanbradach quarry is the second largest sandstone quarry in southeast Wales and has the number of routes to match. It also has the biggest routes on sandstone to date - two-pitch routes up to a height of 50m. However, Llanbradach is not a place for those of an unadventurous nature as the wooded lower quarry is a bit of a jungle and the walls are dominated by vegetation, apart from the Expansionist Wall which penetrates the tree canopy. The Upper Tier has some good routes but they have seen little attention in recent years, and many will need a good clean before an ascent. All the routes have good fixed gear and lower-offs - they just need some TLC.
