Our View

The former limestone quarry of the Craig y Cilau NNR is one of Wales’ most outstanding botanical sites, famous for its variety of rare alpine plants and trees. High on a hillside above the Usk Valley, Craig-y-Cilau consists of a sweeping amphitheatre of cliffs and screes, on the edge of Mynydd Llangatwg. Over 250 plant species have been recorded, including beech, ash, hazel, large-leafed lime and yew. But Craig-y-Cilau’s undisputed jewel is the rare whitebeam. The reserve’s other claim to fame is its 20-mile long cave system – one of the largest in Europe and home to a large colony of lesser horseshoe bats. Around 50 species of bird can be seen in the reserve, including ravens, jackdaws and peregrine falcons breeding among the crags. Other species to look out for include buzzards, kestrels, sparrowhawks and tawny owls. The wooded lower slopes attract tits, redstarts, garden and wood warblers, spotted and pied flycatchers and tree pipits. More than 25 species of butterfly can also be seen.

About the area

Discover Powys

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.

This much wild, empty space is perhaps best typified by the International Dark Sky Reserve in the Brecon Beacons National Park, one of only eleven in the world. The absence of light pollution creates an exceptional spot for star gazing. You won’t find any cities in Powys, just villages and smaller-sized towns, but that’s the way its inhabitants like it. 

Newtown, the largest settlement, is perhaps most famous for being the birthplace of Robert Owen, the founder of the Co-operative movement. Brecon is a market town set on the edge of the Brecon Beacons National Park, while the pretty Victorian spa town of Llandrindod Wells boasts the National Cycle Collection. Elsewhere, Hay-on-Wye hosts a major literary festival every year.

Powys is liberally scattered with castles, burial mounds, hill forts, and other historic markers; Powis Castle, near Welshpool is probably one of the most impressive. And for walking enthusiasts, it’s not just the Brecon Beacons on offer – the Elan Valley describes itself as the ‘Welsh Lake District’.
