Craig Cerrig Gleisiad a Fan Frynych
Craig-Cerrig-gleisiad a Fan Frynych lies in
the heart of the Brecon Beacons National Park, and dramatically
illustrates - on a huge scale - the glacial processes that carved
the shape of this fantastic landscape. The reserve itself is an
upland area of steep sided crags, sharp escarpments, huge lumpy
