This route is primarily intended for cyclists. It could be walked, but a better alternative on foot is to follow Glyndwrs Way National Trail. For the most part it follows quiet country lanes used by just a few local vehicles. It leaves the Severn valley at Llanidloes and climbs to cross high farmland in excess of 300m above sea level. There are a number of fairly steep but short ups and downs. The scenery is second to none throughout with a most dramatic view of the Llandinam wind farm from Llidiartywaun school. The watershed between the rivers Severn and Wye is finally crossed close to where the route joins Glyndwr's Way. From here it is gentle riding all the way to the Mid Wales Bunkhouse. From there it is essentially downhill to Rhayader, although there are a couple of uphill stretches, passing through glorious sheep farming country and old woodland. There is also the possibility of a short diversion to the Gilfach Nature Reserve.
The alternative via the B4518 is equally as dramatic, but is along a slightly busier road and features a long and steep decent and climb at Tylwch.
