This walk visits the fort at Penycloddiau and takes you onto the highest summit of the Clwydian Hills, Moel Arthur, using a section of the Offa's Dyke National Trail. The walk offers some fine views as far afield as Snowdonia in periods of clear visibility. The start is the car park (grid ref. SJ139668) on the minor road across the hills between the village of Nannerch and Llangwyfan.

Exit the car park and turn north (right) onto the Offa's Dyke National Trail. The first section leads up along the edge of a forest to reach open country at a stile. Just after this stile you cross the outer ditch of the Penycloddiau Fort. The way ahead continues uphill along the ridge to reach the summit of the hill from where you can get a good idea of the size of this ancient fort. Staying on the Offa's Dyke path, descend north to the next col below Moel y Parc (Grid ref. SJ121689). Here a number of paths and tracks meet.

Turn sharp right here and follow the enclosed track for about 300 metres. At the end of this track take the gate on your right (Grid ref. SJ124689) and continue across fields and past a ruined building to reach a path junction (Grid ref. SJ135683). Go right here and continue to reach an enclosed track on the approach to Pen-y-bryn farm (Grid ref. SJ140680). Where the track bends to the left, go right through a gate and then immediately left with the hedge to your left. Cross the track leading to Blaen-y-cwm and continue to reach a lane (Grid ref. SJ145679).

Cross this lane and walk up the access road to Bryn-ffynnon and turn left over a stile. The route climbs steeply up a field to join a track. Follow this track until it fades and then go half left across the next field to a stile. Continue uphill over grass aiming for the right hand side of small conifer plantation ahead where you join a track (Grid ref. SJ155677). Turn right along this track and follows it for 2 km to a lane in to the col (Grid ref. SJ147657) just to the south of Moel Arthur. Reaching the small car park, turn right through a kissing gate and follow the path as its climbs across the eastern flank of Moel Arthur. A few minor paths go off left if you want to explore the summit otherwise stay on the Offa's Dyke path as it descends to a lane. The start is a few yards along this lane to the right.

Please maintain social distancing - keep at least 2 metres away from other walkers. Travel restrictions for exercise in Wales and Scotland will be lifted in early July.
