Morlais Castle Quarry is an extensive limestone quarry venue located beneath the ruins of Morlais Castle near Merthyr Tydfil. The rock character features hard Carboniferous limestone with long vertical quarried walls, sharp crimp pockets, and technical slab features. Facing south at high altitude on an open hillside, the crag catches full daylight and dries very quickly under open winds. The route selection provides a diverse mix of traditional climbs and bolted sport routes from Severe to 7b, with Morlais Wall serving as a key classic. The approach involves a ten-minute walk uphill from parking laybys in Pant village. Exposed upland positioning makes it windy, but it dries faster than most South Wales venues.
