The Sugar Loaf mountain stands 596m high in the Brecon Beacons National Park, Wales, near Abergavenny. It is the southernmost of the summit peaks of the Black Mountains. This walk offers many vantage points of (and on) the Sugar Loaf.

The route starts at a Cibi valley farm before ascending through a medieval deer park then ancient moorland. The climb to the summit is short but steep with rewarding views. The meandering descent passes grazing sheep and crosses a spring before a near vertical climb, then back onto Sugar Loaf common. The final decline is through woodland and pasture to the start.
