For many people, the three peaks of Corn Du, Pen y Fan and Cribyn define the Brecon Beacons. There's several ways to tackle the hills, but I think the finest is from the Storey Arms centre on the A470. Buses between Merthyr Tydfil and Brecon all stop here, so there's reall no excuse for using the car. This route heads up to Corn Du on the Y Gyrn path and follows the main ridge path, before dropping down to Upper Neuadd Reservoir and the narrow Rhiw yr Ysgyfarnog.
