This annual 20 mile mountain walk over the hills surrounding Tal-y-bont on Usk normally takes place in October each year. The route goes clockwise one year and anti-clockwise the following year, and takes in the summit of Tor-y-Foel, Chartists Cave on Mynydd Llangorse, Trefil Quarries, the summit of Pant y Creigiau, the roadside at Torpantau, up onto Craig y Fan Ddu, the summit of Carn Pica and back down to Tal-y-bont. The views over the Tal-y-bont Reservoir and the forestry, right across the whole of the Beacons and the Black Mountains are stunning on a fine day, but beware! If the weather is poor you need to know how to use a map and compass, especially if you are looking for Chartist Cave!

There is also a shorter walk of ten miles, which follows the canal out of Tal-y-bont and around the village, taking in the Taff Trail.
