Park on the Allée du Bois des Folies in Bondoufle.
(S/E) Take this road on the opposite side of the roundabout, pass under the D31, continue between the fields and reach the edge of the woodland.
(1) Carry on straight ahead into the woodland until you reach a gate at the edge of the woodland.
(2) Turn right onto the path at the edge of the Bois des Folies. At the southern edge, continue straight ahead across the fields until you reach the edge of the Bois de la Tombe.
(3) Turn left at the edge of this new woodland and head towards the entrance to Lisses.
(4) Turn right, passing in turn a water tower, the pumping station and the electricity substation. Cross the Route de Mennecy with care and continue along the path until you reach the bridge over the departmental road.
(5) Go under the bridge, take a moment to admire the graffiti, then reach the Vanne Aqueduct.
(6) Carry on straight ahead and you’ll reach the gates of the Domaine de Montauger park.
(7) Take the path on the right – theGR®11C, marked in red and white – and walk to the main entrance of the estate.
(8) Cross the road and take the marsh path to the left of the car park; this is still theGR®. Continue on to the village of Écharcon.
(9) Turn right onto Rue Philippe Père and carry on until you reach the D26.
(10) Cross it carefully to join the Chemin de Monthléry. Pass under the power lines before reaching the Braseux farm.
(11) Leave it on your left – take the opportunity to admire the site and the beautifully restored buildings – and take the rural track from Vert-Le-Grand to Lisses via Montaubert towards the recycling centre. Watch out for lorries as you go round the roundabout and head straight on. You’ll reach the junction at the Ferme de Montaubert.
(12) Continue straight ahead along a field, then follow the western edge of the Bois des Folies to reach the junction you passed on the way out.
(1) Turn left and follow the route you took on the way there in the opposite direction to return to the car park on Allée du Bois des Folies (S/E).
