Coed y Cerrig National Nature Reserve is in the southern part of the Black Mountains within the Brecon Beacons National Park.
Lying in a small deep valley shaped by glaciers, this small wooded area is hidden away but the road through the reserve was once a busy railway line, carrying materials to construct the Grwyne Fawr reservoir.
A wet alder woodland covers the valley floor – these trees used to be coppiced to make charcoal and soles for clogs.
A mixed woodland, full of fragrant bluebells in spring, clings to the steep valley sides and an oak and beech woodland grows in the deeper soils at the top of the reserve.
There is an accessible boardwalk over the wet valley bottom and a short but steep circular climb through the woodland.
The walking trails are waymarked from start to finish.
Look out for the information panel at the start of the trails.
Notice the multi-stemmed alders – evidence of ‘coppicing’ (cutting to near the base and resprouting).
In spring, look out for showy marsh marigolds and the delicate pink ‘umbrellas’ of valerian growing along boardwalk, and smell the fragrant bluebells growing along the path section.
Enjoy the swathe of bluebells along the path in spring.
