There is a fine walk from the village of Clyro up through Pen-y-lan Wood towards Great Gwernfythen farm, where you can join a country lane back to the village. As you work your way through the trees north west of Clyro, you follow the soothing Clyro Brook for a short stretch. The round trip is only about three kilometres, but there is a fair bit of climbing. Your reward is sweeping views of Hay-on-Wye and the Hay Bluff, on the edge of the Black Mountains.
