1 Turn your back on the skyline map and turn right on a path that runs close to the edge of the common. Cross the B4580 to access the northern part of the common and go to the right when the path forks. As you approach the far end of the common, take a worn path on the right. There are several other paths but only this one actually goes anywhere - you should recognise it because it's much more heavily trodden than the others. There's bracken to the right of it and gorse bushes and rowan trees to the left. It soon leaves the common and continues as a grassy track. Follow it only for a very short distance, keeping your eyes open for a path branching off to the right at a stile.
2 Follow the path across a gorse-studded, brackeny pasture, heading for the far left corner. Cross a stile, continue to another and then go straight on to the B4580. Turn left on the footway then first right on a quiet lane. Follow it to a junction, where you turn right, then immediately left. Pass the turning to Cwmsychtyn and continue to another junction, where you take a footpath that uses the driveway of The Old Farm, then crosses a lawned area to a stile. Cross a track to enter a field and go diagonally to the far corner. Cross to the next field and head towards the far left corner, then into Gwalia Wood.
3 Follow a path through the wood and into a field. Go diagonally towards the far corner, guided by a group of tall sycamore trees, and then across the next field to a stile giving access to woodland at Sheep Walk. Turn left, soon crossing a track and going straight on as indicated by a waymarker. The path is overgrown by brambles, but stick as close to the line of it as you can and you'll soon come to another waymarker, sending you left by a laurel hedge to meet a grassy path. Turn right, right again shortly, still by the hedge, then right once more to join Offa's Dyke Path (you will recognise it by the acorn logo that signifies a national trail).
4 Follow the path beside the prominent earthwork of Offa's Dyke through beautiful Candy Wood, above the steep slopes of Craig Forda. Ignore branching paths and continue through the adjacent Racecourse Wood until a stile gives access to Racecourse Common. Turn right, leaving Offa's Dyke Path, and follow a waymarked path close by the edge of the common. Ignore branching paths and you will soon find yourself back at the car park.
