Start from the car park at the Petit Bois leisure centre, next to a small pond with a hiking sign and at the foot of a wooden tower for zip lines.
N.B.1. Several of the paths taken are not shown on the IGN map. This is particularly the case between (S/E) and (2) and between (6) and (9).
N.B.2. For the most part, the route combines two trails designed and marked by the Auray-Communauté Tourist Office, the Route de l'Étoile and the Route de l'Eau. The names of these routes are mentioned at certain intersections, and this description refers to them.
Yellow markings
(S/E) Facing the pond, turn right, go to the back of the car park and leave the tower on your left. Between two shelters, follow the Route de l'Étoile to the right. Walk along a fence on your left and go around a tree-climbing park. At the end, turn right, walk along an embankment on your left and ignore the paths on your right.
After a right turn, cross a stream by jumping over it. At the T-junction that follows, turn right. Cross the stream again. At a fork, veer left. At the T-junction, follow the route de l'Étoile to the left. Go straight ahead on a wide path for about 500 metres and ignore all the paths branching off to the sides.
(1) Leave the wide path by taking a footbridge on the right over a stream (be careful to spot this turn-off) and follow a path through the woods. At a T-junction, turn right (west). You will arrive at the Rond-Point de l'Étoile. Take thethird road on the left, the Route domaniale de la Croix Tortorec, a wide stony path. Continue straight ahead until you reach an information sign on the right-hand side.
(2) Take a path on the right through the woods, which quickly leads to the Menhir Braz. Retrace your steps.
(2) Continue south-southwest on the wide stony path for about 600 metres.
Orange horseshoe markings
(3) At a crossroads, at the boundary between forest plots nos. 46 and 47, continue straight ahead (ignore the yellow markings on the left). After a few metres, take a narrow path on the right. Then turn left and go around a pond on the left. Cross the pond's spillway, which leads to a wide path, and follow it to the right.
Yellow markings + orange horseshoe
At the T-junction that immediately follows, turn right onto a wide stony path. Ignore a narrow path on the right and you will soon come to a signpost.
(4) Take the path on the right through the undergrowth that leads to Menhir Bihan. Continue a few dozen metres beyond this and you will reach a collapsed dolmen. Retrace your steps.
(4) Continue north-northeast on the wide path. After about 200 metres, note the old Fionnec wash house on the left. Further on, cross a small road at the entrance to Lambel and continue straight ahead on the Route domaniale de l'Arboretum (named Ligne des Loges on the map). Leave the Circuit de l'Étoile route on your right in the undergrowth and continue straight ahead, north-northwest, until you reach another road.
No markings
Cross the road, ignore the yellow arrow pointing left towards the route de l'Eau and continue straight ahead on a very wide path. Note the old engraved boundary stone on the left.
Yellow markings
(5) Shortly afterwards, rejoin the Route de l'Eau and follow it to the right through the woods. Descend and note a pond on the left. At a crossroads, turn left. Shortly before reaching a road, turn left and stay parallel to the road. At a T-junction, turn left again and you will come to a fork.
(6) Turn left and you will soon reach a stream with the Fontaine des Sabotiers fountain on the other bank (ignore the sign that seems to indicate that the fountain is further along on the left). Retrace your steps.
(6) Back from the fountain, turn left at the fork. Cross the stream, continue on the path opposite and wind your way through the undergrowth. At a crossroads, turn right and immediately ignore a path branching off to the right. Walk north-east downhill and go straight ahead at the next two crossroads. Cross a stream via a footbridge and climb up opposite.
No markings
Come out onto a small road and follow it to the right at an acute angle (ignore the yellow markings continuing opposite).
(7) After about 100 metres, at the entrance to a slight right-hand bend, leave the road and take a path on the left that starts at the foot of a wooden post (remnant of an old forest barrier; be careful to spot this turn-off). Stay on the main path, heading east, slightly downhill then slightly uphill, and ignore any tracks on either side. At a clearly marked junction, go straight ahead and descend steeply.
Yellow markings
(8) At the bottom, rejoin the Circuit de l'Eau and follow it to the right. Walk along a fenced meadow on your left and cross a stream. Cross the gravel path leading to a house, continue straight ahead and ignore a path on the right. Walk along a fenced pond on your left, then take two successive footbridges over streams. Then walk along a stream on your left.
Yellow + red and white markings
The purple line representing theGR®38is inaccurate here: the junction with theGR® is at the R for "Ruines" on the 1:25,000 map.
At a T-junction, turn left, cross the stream and go uphill. At the top, turn right. At a three-way junction, go down to the left to the edge of the Étang du Petit Bois.
Yellow markings
Then turn left to walk around the pond in a clockwise direction. Take the dyke, cross the weir and turn right. Walk along the pond, pass a chain and make a first turn right then left to cross a road. Turn right-left again and you will return to the car park where you started (S/E).
