From the footbridge you can get on to the old Pensarn Road, via a cycle path (right, just past the station). Follow Pensarn Road to where it goes under the A40, then take the first left on to Penmorfa Lane. Take the first left off this and it’ll take you straight to Cranc, avoiding the busy roads and roundabouts. Or you can turn left at the end of the cycle path and go on to old Llangunnor Road (part of this is now a path), which would be quicker. Maybe go back that way.
