Starting point: Forges-les-Bains, a pretty village typical of the Hurepoix region, home to many fine houses and châteaux. The route starts from the church forecourt. Large car park to the north of the church, small car park to the south and below the church.
(S/E) From the small car park, with your back to the church, head down to the right, cross the main road (D97) and slip into the Allée des Soupirs (dead end; old water pump). At the end, turn right and, at the T-junction that appears immediately, turn left. You will come out onto Rue des Puits (signposted further on) and follow it to the right and round the bend.
(1) At the junction, where the street becomes Rue des Pré aux Chevaux, take a path that branches off diagonally to the right (Chemin de Chardonnet aux Richards; not easy to find, leave the houses on your left). Cross Rue du Pré aux Chevaux and continue straight ahead.
(2) You’ll come out onto a very quiet local road; follow it to the left, climbing up between horse pastures. Stay on the road which, after the 148m mark, descends into a tunnel of greenery.
(3) At the junction with the D838, turn left onto the small road towards Bois d'Ardeau (do not follow the D838).
(4) Before the village, at the edge of a wood, take a sandy path on the left. Follow this path as it climbs, ignoring a turn-off on the left. At the next junction (elevation 142), join theGR®11and follow it to the left (red and white markings). Cross an area of old trees, including a remarkable hollow tree large enough for a man to stand inside.
(5) At the T-junction, turn right onto theGR®. Leave the woodland and pass between fields. Ignore a path branching off to the right and continue along the edge of the woodland on your right. At the T-junction, turn left. Enter the woodland, follow theGR® and walk along the edge of the woodland until you reach a junction.
(6) Then turn left and enter the woods again, following the GR®. The path turns right and descends gently. Continue along a tarmac road, still on a slight downhill slope.
(7) Walk past the Château de Forges-les-Bains. Then cross the D97 and walk briefly up the street opposite (pharmacy on the right) to reach the church car park (S/E).
