Climb to the highest mountain in the Black Mountains on this challenging walk in the Brecon Beacons. The walk starts from Castell Dinas just of the A479. This Iron Age hillfort has the highest castle in England and Wales. There is also a car park which makes a good start point for the climb to Waun Fach. From here you follow bridleways past Rhyd-y-car farm before turning south past a series of cairns. The final section turns east to take you to the 811 m (2,661 ft) summit.
You could also start the walk from the nearby village of Talgarth. The village is located just a few miles north of Castell Dinas.
To extend your walking in the area you could head to the nearby Grwyne Fawr Reservoir and Mynydd Du Forest where there are miles of walking trails and mountain bike trails to try.
