Leaving from The Blaen-Y-Glyn waterfalls, the route ascends moderately to Craig Fan Ddu, a fine ridge with stunning views, and then to to Fan-Y-Big (795m) and the surrounding Beacons, before climbing steeply down, and then up again to climb along Craig Cwm Cymwyn to the summit of Cribyn (795m). From the summit here, the route drops down to the Roman Road past the Neuadd Reservoirs and through Taf Fechan Forest and back to the starting car park.
