Parking at Pont-Plat, located near the stadium on the edge of the D102, which connects Plobannalec and Lesconil.
Yellow signposts.
(S/E) Leave the car park and take the first road on the left. The Kervignon Dolmen is on the left near the sports field.
(1) Go around the EDF transformer to reach the Kervadol Dolmens (signposted on the right about 200 m away), then retrace your steps and continue along the gravel path. Go around the hamlet of Kervadol.
(2) At the crossroads with the Route de Tréffiagat near a house, look for a small cross on a pedestal on the right (Croix de Kerbrizen). Turn left onto the road, then right at the next junction until you reach Penbanal. In the hamlet, turn left onto the narrow grassy path between two farm buildings until you reach the old Birinik railway line (known as the Transbigouden), which linked Pont-l'Abbé to Saint-Guénolé.
(3) Follow this wide track to the Neolithic site of Quelarn on the right.
(4) Visit the site. On leaving, cross the road and take a narrow path to the Dolmen de Tronval. The wooded path leads to the road where you turn left and then right at the crossroads. Follow this road for about 100 metres.
(5) At the first road, turn left, ignore the first road on the right and follow the road towards Keraleuc. Pass the hamlet and arrive at the Kervignon equestrian centre.
(6) Turn left towards Le Moustoir, which you will leave on your left, and notice a tall medieval cross on a circular base on your right. You will arrive at a crossroads.
No signposts
(7) At the crossroads, look for a semi-buried fountain, turn right to return to Pont-Plat. About 500 m further on, note the Kerfuns dolmen on the right, at the access road to Kervadol, and the Kervignon dolmen already spotted on the way there.
(1) Walk along the sports field to reach the Pont-Plat car park (S/E).
