About Craig y Cilau

A limestone escarpment on the north side of Mynydd Llangatwg, about 2 miles south-west of Crickhowell, designated a National Nature Reserve in 1959. The cliff sits above Old Red Sandstone and below Twrch Sandstone; the limestone is riddled with natural caves and tunnels. Hard trad climbing on quality limestone.
