Craig-y-Cilau National Nature Reserve Crickhowell, Powys The reserve forms part of an impressive limestone escarpment that outcrops along the north eastern edge of Mynydd Llangatwg. It is one of the largest upland limestone cliffs in South Wales. The limestone rock rich in nutrients gives rise to soils that support a wide variety of plants, some rare. Of particular note are several species of rare whitebeam growing on the cliffs, one of which is only known from this locality. Some 50 species of bird have been recorded breeding here. The limestone itself is peppered with caves, and one of them Agen Allwedd is an important winter roost for lesser horseshoe bats. The Countryside Council for Wales is committed to creating opportunities for everyone to enjoy the countryside. National Nature Reserves are no exception. On some reserves the Countryside Council for Wales has provided additional paths. On others, access on foot is unrestricted and visitors are welcome to wander freely. Where possible, the Countryside Council also provide facilities to add to visitors' enjoyment of reserves such as bird hides, information points, guided walks and displays, and facilities for the disabled. Signs at entrances welcome visitirs to each reserve and provide basic information.       Reset Map Position About our location: About a mile from Crickhowell on the A4077 Safety: The Countryside Council for Wales makes every attempt to ensure that your visit to a reserve is enjoyable and safe.
