Park in front of the Maison Pour Tous du Moulin Vert, in the north-west district of Quimper.
(S/E) Cross the grassy esplanade at Moulin Vert, cross the Steïr via the footbridge. Turn left and follow the river upstream along the left bank until you reach the weir, which you cross.
GR®38markings: White and Red + MTB
(1) Turn right onto the path now on the right bank and follow the river upstream along the marked path that passes under the railway bridge. Walk past a special needs school on your left.
(2) Cross a small wooden footbridge and continue following the river upstream along the path bordered by a large meadow. Opposite the ring road bridge, turn left, climb the path that goes round retention basin no. 31 and joins a tarmac road at a barrier. Follow this road, which crosses over the railway line, runs alongside a new retention basin (No. 30) and leads to a large roundabout. Go round it on the left, following the designated paths, and pass under the D100 ring road.
No signposting
(3) After passing under the bypass, at a triangular road sign indicating the roundabout and bearing aGR® marker, turn left onto a small path which quickly joins a wide, ascending path.
Please note: theGR® route shown on the map is no longer accurate. Continue along this gently ascending path, which overlooks the D100 and passes close to the small Saint-Conogan Chapel. As you pass, look out for a very old chestnut tree on the left. You will come to a tarmac section at the Allée de Kerayen.
Turn right and join a road.
(4) Turn left and follow this road, which crosses over the ring road, and continue. View of Kerfeunteun, a northern district of Quimper. At the Quimper entrance sign, a pavement on the right offers a safer route.
(5) Just after a magnificent garden with a goldfish pond, turn right into Allée de Kerlezanet, pass a pretty stone house on the left and turn right. Leave the houses on your right and follow a narrow west-facing path that descends gradually into the valley and ends beneath the viaduct.
(6) Move slightly to the left, then take a narrow path on the right that climbs steadily. If you come across retention basin no. 26, turn back as you have veered too far to the right. Follow this path, which crosses a natural gas pipeline (sign 107), until you reach a barrier blocking the entrance to the path. Continue to the next junction.
(7) At the “Give Way” sign, turn right and follow the road for about 700m. Pass a landscaping company, then a 70km/h speed limit sign. When you see the electricity pylons and glass recycling bins on the right, turn left onto a track. Viewpoint over the countryside and the Locronan mountain.
(8) Follow this downhill path, which turns right before passing under the power lines and reaching a crossroads. Climb a small embankment between two trees, cross the natural gas pipeline (yellow marker) and continue up the path opposite. Continue following the trail through the woods to reach a high point. At the next crossroads, take the path on the left, which becomes a wide sunken track and ends with a row of beech trees before emerging near the roundabout opposite the Troheïr water treatment plant.
GR®38markings: White and Red
Go round the roundabout on the right.
(3) Retrace your steps along theGR® route. Pass the entrance to the Saupiquet factory on your right and cross the railway line.
No markings
Turn right, head towards a residential area and pass through a narrow section with a 30 km/h speed limit.
(9) At a gate marked No. 46, turn left and follow the path which rejoins the route taken on the way out.
GR®38markings: White and Red
(2) Turn right and retrace your steps along the route you took on the way out until you reach the weir, which you cross.
No markings
(1) Head up the slope opposite, leaving the path that runs along the left bank of the river. You’ll end up near the Coat Ty Dreux community gardens on the left. Join Rue Charles d’Orléans and follow it to the left.
(10) At the electricity substation on your left, turn right onto the footpath Allée de Coat Ty Dreux. Follow this path, which leads back to Rue Charles d'Orléans, which you left earlier. Follow it to the right for a few metres, then turn left to cross the footbridge over the Stéïr. Continue along the path taken on the way there to return to the car park (S/E).
