Craig Cerrig-gleisiad National Nature Reserve

Recommended by Visit England Logo
Overview
The Craig Cerrig-Gleisiad NNR, just a few hundred yards from the A470 Merthyr Tydfil-Brecon road, is an atmospheric amphitheatre created by the 500ft (150m) high crags of Craig Cerrig-Gleisiad. The NNR’s prize botanical feature is the rare arctic-alpine plants at their southern limit in Britain – such as purple saxifrage and mossy saxifrage – which cling to the reserve’s ledges, gullies and crags. They are just some of over 500 plants that have been recorded. The vertical woodland of the crags supports trees and shrubs including hawthorn, rowan, mountain ash and rare whitebeams. But the cliffs only make up a fraction of the 156-acre (63ha) NNR. The lower slopes are home to mixed woodland and flowers such as orchids and anemones, while the moorlands above supports heather and bilberry. Around 80 different bird species either visit or breed in the reserve. Peregrine falcons nest on the cliffs and the raven, merlin and red kite can also be seen in the skies, the latter especially at Craig Cwm-Du. Summer visitors include wheatears, ring ouzels, skylarks and chaffinches.

About the area
The largest unitary authority in Wales, Powys covers an area of approximately 2,000 square miles. Much of that is mountainous because it actually has the lowest population density of all the Welsh counties.
