Depart from the rest area located along the D764, halfway between La Feuillée and the Col de Trédudon.
(S/E) Leave the rest area to the north and carefully cross the D764. On the other side, take the path on the left below and follow the D764 on your left. Continue along a small road and ignore the entrance to a property on your right.
(1) At the intersection, turn right. Head east and stay on the gravel road until you reach the entrance to Trédudon l'Hôpital.
(2) At the crossroads, follow the road on the left towards Le Relecq. Ignore two turnings on the right and cross a river. Continue along the road to Trédudon le Moine.
(3) At the intersection, keep left. Pass a memorial stone and continue north-northeast on the road.
(4) At the junction of the hiking trails, take the path on the left and begin the climb towards the ridge. Ignore a path on the left and then one on the right at elevation 340. You will soon come to a fork in the road.
(5) Turn left and continue climbing (ignore the signposted Abbaye de Relecq circuit on the right). Walk alongside a copse on your left and follow the ridge south-west then west-south-west. This will take you to the summit of Roc'h ar Feunteun.
(6) Continue along the ridge path to the west-southwest, through moorland and peat bogs.
(7) Cross the D36 carefully and continue straight ahead. At the crossroads, go straight ahead and reach the summit of Roc'h Trédudon.
(8) Continue west-southwest and descend towards the television antenna. Go around the left side of the site, which is fenced off and closed to the public, and you will reach the D764.
(9) There are two options:
- follow the road to the left (beware of heavy traffic). After about 400 m, cross the road carefully and take the forest path downhill opposite for 100 m (elevation 328).
- or turn right for about 100 m, then turn completely left to follow a path parallel to the D764 on your left and rejoin the circuit at elevation 328.
(10) Leave the main path, which continues straight ahead, and turn left, south-east, onto the marked Roc'h an Teuz trail. Descend the gentle slope.
(11) At the crossroads, continue straight ahead on the marked path, through moorland and then a copse.
(12) At the crossroads immediately after crossing a stream, leave the marked trail and take the path on the left marked with a sign indicating Rozar Had. Come out onto a small local road and follow it to the left. This will take you to the car park at the rest area (S/E).
