Departure from Gazeran station (Transilien N line, on the section between Paris-Montparnasse and Chartres).
Yellow markings
(S/E) Leave the station (which is actually just a stop) to the north, i.e. via the platform for Chartres-Paris (if coming from the other direction, take the underground passage). Pass a small car park and follow Rue de la Gare. At the crossroads, turn left onto Route de la Gare, still heading north.
No signposts
(1) Turn right at a sharp angle and carefully follow Route du Bray on the left-hand side. Pass through Le Bray and ignore the side roads.
(2) Pass under the railway bridge (caution, the passage is narrow). Continue along the road and pass a large house at a place called La Mare.
Yellow markings
(3) Before reaching Les Mandreuses (houses), turn right onto a path through the fields. The path heads south-west for a good kilometre. At a crossroads (barrier), turn left at a right angle and you will reach the D150 road. Follow this road to the right.
(4) At the Champs Roux farm, turn left onto a small road heading south towards Orcemont. After a slight bend to the left, take a path on the left that heads south-southeast then south between meadows and woods.
(5) Cross a small road and continue on the path, which now heads south-west. You will reach the Romaray woods, along the edge of which you will walk to reach the Drouette.
(6) Walk along the river on your left (nice view of Orphin church).
(7) When you reach a road, take a path on the right that climbs briefly to join a small road, which you take on the left. At the junction with a larger road (D150), turn right. Do not cross the road and stay on the right-hand side, on a wide grassy verge that keeps you away from the carriageway.
(8) Cross the road (with caution) to enter a forest path. Walk west for about 1.2km.
(9) At the edge of the forest and meadow, turn left at a right angle. After about 600m, you will reach the PR® crossroads.
(10) Take the path on the right at a right angle, towards Petit Bel-Air. About halfway to this place, walk along the left-hand side of the wall of the Sauvage zoological reserve. Arrive at Petit Bel-Air. Cross the road (D62) to take the path opposite, into the forest.
Red and white markings
(11) At the junction with a clearly visible path coming from the left, turn right onto a less distinct path (GR®655). Then turn left onto a small road and follow it to the right for a few hundred metres.
(12) Turn left at a right angle onto a path heading north-northwest, which runs along the edge of the Bois des Cents Arpents (on your right) and a cultivated plot (on your left). Reach a crossroads at the Etang Guinegat and continue on theGR® which heads northwest.
(13) At the crossroads, follow a small road to the right (north-northeast).
(14) Leave the road when it turns right and take the path on the left at an acute angle. After a few metres, turn right and follow a path between the fields to the north.
(15) When you reach Le Fléau, continue north along a lane that soon curves to the right. At the end, the tarmac gives way to a path. When you reach a road, turn left, go under the railway bridge, turn left and go down to the entrance to La Bellandrie.
(16) Turn right onto a path that winds between a few houses. Cross a road and walk along the Étang de Saint-Hilarion on your left. Continue along the Guéville (which is not always visible due to the presence of hedges), heading north-east then east-north-east.
(17) When you reach a road, continue along the path, still heading east-northeast. Further on, the path climbs to the level of a railway line.
(18) Pass under the railway bridge and turn left along the path. At the next junction, turn left again and pass under a second railway bridge. Walk along the edge of the forest on your left. You will reach a small lane and a car park.
(19) Continue east-northeast and, at the crossroads, continue along Rue du Haut Cazeran towards the town centre. At the next crossroads, continue straight ahead along Rue de l'Église.
Yellow markings
(20) After about 100 metres, leave the street and turn right (south) onto an uphill path. Come out onto Route de la Gare and follow it to the left.
(1) Continue south on Route de la Gare, then turn right to reach the station (S/E).
