Craig-Cerrig-gleisiad a Fan Frynych National Nature Reserve Libanus, Powys High in the Brecon Beacons this reserve was once part of an area known as the Great Forest, although it is not strictly a forested area but an ancient hunting and farming forest. A small reminder of a forest is seen in the scrub woodland and scattered hawthorn on the lower slopes of the reserve. The steep sided crags of Craig Cerrig Gleisiad and Cwm Du together with the escarpment of Fan Frynych and the lumpy moraines at lower levels are all evidence of the movement of huge rivers of ice during the last Ice Age. The artic-alpine plants are some of the most interesting features of this site. The most inaccessible cliffs and crags provide refuge from grazing sheep for this rare vegetation. A variety of upland birds can also be seen here including peregrine and ring ouzel. 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: The A470 passes Craig Cerrig Gleisiad between the Storey Arms and Libanus.
