Park in the Beg ar Vilin oyster farm car park.
(S/E) Go left along the coastal path (GR®34) that leads to the small port of Castel.
Pass the port and the hamlet, then take the steps on the right (signposted GR®34).
Follow the GR®34 along the seafront. You will pass a point with a house before arriving at Varlen beach. Keep following the coastal path.
(1) The GR®34 takes you back to the road. Turn right to go down to Pors Hir beach. Continue along the GR®34, as close as possible to the sea.
(2) Go back and forth to admire the panorama at the "Pointe du Château", then return to the GR®34, which takes you across the moor to the Gouffre. Be careful not to walk on the pebble beach. This area is too sensitive. A path below the pebbles is suggested. Continue to follow the GR®34.
(3) Go down the steps to the Gouffre car park. Just before you reach the car park, take the path on the right past a pretty sentry box, then pass the Maison du Littoral. Continue straight on to the next crossroads. At this point, you can turn right to go to the Gouffre and back.
(4) Fork left along a small reservoir to reach the road. At the road, turn right and, a few metres further on, take the path on the right at the corner of a stone house. Stay on the coastal path (GR®34) to reach the Pors Scarff parking lot.
(5) Leave the coastal path to go up the road on the left. Continue along this road. Leave a road on your right and continue straight ahead.
(6) At the next crossroads, leave the asphalt and take the grassy path which goes off to the right (Yellow markings) and continues to the left. Reach the hamlet of Feunten Guen, then the road (Bourg de Plougrescant/Le Gouffre). At the road, turn left and continue for about 200m to the next crossroads.
(7) Take the hairpin bend into the grassy path immediately to the right, alongside the house. Follow this path and at the next crossroads, continue along the left-hand path. You'll find a pretty sunken path lined with embankments that leads back to the road.
(8) Turn right, then left. At the crossroads, go straight ahead and follow the road to the back of the properties.
(9) This road becomes a path. Follow it. At the road, cross over to take the path opposite, which leads to another road. Keep right, passing a property.
(10) After the building complex, take the path on the left at the wash-house and fountain. At the end of the path, turn left onto the road and go back to the starting point (S/E).
