The route is marked with blue and white markers.
Starting point Rue du Heaume in Ablis, a stone's throw from the church (a Péguy plaque has been affixed to the east side since 2014).
(S) Head to the South interchange via Rue du Heaume, Rue de l'Église, Place des Fées, Rue d'Arras, then turn left onto Rue de la Libération (D177). At the roundabout, turn right and take the bridge over the N191.
(1) Turn right and walk below the N191. Then turn left.
(2) Turn right, heading west, and continue straight ahead through fields and copses.
(3) When you reach the N10, go down 40 metres to the left to take a small tunnel passing underneath. Then turn right and quickly left. Leave a path on the left and join a road. Follow it to the left for a few metres and continue straight ahead on a track. At the end, turn right onto a road and cross Gourville.
At the tunnel exit, you can also turn right (up to the plateau) or left (200 metres shorter) to reach Gourville, a picturesque village with an elegant manor house.
(4) Continue along the road and take the tunnel under the motorway. Then pass under the old railway viaduct and continue for 150 metres.
(5) Turn left onto a wooded lane: the markings are faint and sporadic (high forest). The lane leads to the surrounding wall of Esclimont Castle, which you follow southwards for one kilometre.
(6) Beyond this, markings starting at Rue du Parc (left, and second street on the right) lead to the beautiful Saint-Symphorien Church.
(7) Come out onto the D18 and follow it to the right. Take the first left, Rue des Merisiers. Continue along a beautiful rural path following the route of the old railway line.
(8) Cross the D122 and continue along the path opposite. After about 500 m, turn left towards a copse (known as Malavisé), walk between the fields, pass the copse and join the D331-3.
(9) Follow this very quiet road to the left. After about 400 m, turn right onto a path. Turn left shortly afterwards. At the T-junction, turn right and join the old railway line.
(10) Then turn left. At the next junction, go straight ahead. Shortly afterwards, cross a road and continue along the small road opposite (Rue des Lavoirs). Cross a stream (wash house) and continue straight ahead.
(11) At the T-junction, turn right and, after about 50 metres, turn left into Rue des Perrets.
(12) At the next intersection, turn right and pass by the foot of Saint-Georges Church. You will come out onto the D116a (Rue de la Mairie on the left, Rue Charles de Gaulle on the right) and follow it to the right for a few dozen metres.
(13) When the street turns right, leave it and take a path on the left (be careful to spot this turn-off). After about 100 metres, join the platform of another disused railway line and follow it to the right.
(14) Take the D116-7 to the left for 200 metres.
(15) Turn right onto a rural path. When a path comes from the left, turn right (north-northwest). Follow the railway line and pass the station area (not the highlight of the route!). In Gallardon, reach the crossroads between Place de la Gare and Avenue de la Gare (E).
Beautiful arrival at Pont sous Gallardon.
