PEN CERRIG CALCH
This is a nine and a half mile circular walk in one of the wildest areas of the Black Mountains, we pass through an ancient hill fort before striking out into the hills. The terrain covered includes grassy paths, open moorland farmland and a minor road.
There are no facilitlies along the route, there are pubs, cafes and shops in the nearby town of Crickhowell.
The crags and screes support a variety of rare plants, including hawkweeds, ferns, mosses, liverworts and lichens. This is an important area for its upland breeding birds, including red grouse and golden plover.
This is a strenuous route and may well be wet underfoot in places, hiking boots are recommended.
