Craig Cerrig Gleisiad Nature Reserve

  • slide

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 moraines and a large shady north-facing cwm. These steep slopes are welcome refuges for communities of arctic-alpine plants and some rare birds, while there are also a variety of smaller habitats within the upland.

The area has been inhabited for thousands of years, as a great many archaeological remains lay testament to – including an Iron Age village and a Roman road and tollhouse. Many of these are scheduled ancient monuments.

The reserve is actively managed by allowing grazing cattle and sheep to roam and roll, which helps control bracken levels.
