Beacons View, near Monmouth
Walk through heathland and woodland
Coed y Cerrig National Nature Reserve is a wooded area in a small but deep valley which was shaped by glaciers.
A wet alder woodland covers the valley floor, which you can explore on our accessible boardwalk.
There is also a short but steep walking trail through the mixed woodland which clings to the steep valley sides and is full of fragrant bluebells in spring.
The reserve is in a peaceful part of the Brecon Beacons National Park but the road through it was once a busy railway line, carrying materials to construct the Grwyne Fawr reservoir.
The walking trails are waymarked from start to finish.
Look out for the information panel at the start of the trails.
Find out about walking trail grades.
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.
