NCN Route 818 is a cycle route in Mid Wales, that links NCN81 at Blaenycwm near Cwmystwyth and NCN8 at Llangurig. It forms a shortcut for the NCN81 route, though is more hilly. The road gets steadily better heading east, turning from track to road at the county boundary and turning from minor road to the trunk A44 after crossing the Wye.
