From the car park at the Visitors Centre (£3 fee), we head south west, along tracks and a metalled road. We will then be walking below the long ridge of Fan Frynych to our left. We begin our gradual climb, which will give us good views of the Fforest Fawr section of the National Park, and into Blaen Senni, the source of the river Senni. As the path climbs gently, on a clear day, we will have stunning views of Corn Ddu and Pen y Fan. We then pass a large Cairn before eventually reaching the trig point at 629 m. We now follow the beautifully open and airy ridge downwards, with views towards Brecon and the Central Beacons beyond. Our route passes through farmland ( dogs must be kept on a lead) and on to meet the path we took on our walk in, from where we make our way back to the Visitors Centre.
