The ground varies from being rocky and uneven in some sections to very wet underfoot in others. Hiking boots are recommended.
This is an eight mile circular walk along which you'll see some of the best features the Beacons have to offer from the Sarn Helen Roman Road to the nature reserve of Craig Cerrig Gleisiad to the dramatic peak of Fan Frynych. Terrain covered includes farmland, green paths, a stoney Roman Road and open moorland.
There are toilets, shop and cafe at the Brecon Beacons visitor centre. There are no other facilities along the route.
The ice carved cliffs of Craig Cerrig Gleisiad are home to the rare arctic-alpine purple saxifrage while down in the valley hawthorn, rowan and whitebeams thrive. The reserve is also home to a wide variety of butterflies and around eighty species of birds including peregrines, merlins, ravens, kites and ring ouzels.
