The route starts from the car park of the Théâtre de la Nacelle, Rue de Montgardé, in Aubergenville.
(Out/Return) As you leave the car park, take a few steps to the right and enter the Parc du Château du Vivier. Head up to the right, opposite the château, to see the fountain and the small educational farm. Then head back towards the château and go round it to the right to arrive at the entrance. Go out through a small gate and turn left into the Grande Rue, cross the Rue du 8 Mai 1945 and continue along the Rue du Grand Aulnay. At the T-junction, turn left into the Impasse Villa d’Artois, then climb a flight of steps to arrive near the Montgardé Clinic.
(1) Walk up to the right for a few metres and, opposite, take the small path to the left of the ‘Centre hospitalier privé du Montgardé’ entrance sign. At the Fork in the road, turn right to follow aPR®® trail, which is very clearly marked in yellow. Ignore all side paths for about 1.4 km until you reach some houses.
(2) Continue along the Chemin des Galigots, then at the next junction, head up to the left onto the Route de Montgardé. At the fork in the road, facing a wall, turn left onto the Chemin de Montgardé (signposted), which continues alongside the castle’s surrounding wall until you reach a T-junction. Turn right until you rejoin the Route de Montgardé, which you should then take to the right.
(3) When you reach the green gate, turn left onto thePR®® and, at the T-junction, turn right. Walk alongside a fence on your left and, further on, turn left onto Rue des Huguenots.
(4) At the fork in the road, continue downhill to the right along this same street, pass by a wash house, then carry on straight ahead. At the Stop sign, ignore the road on your right leading to Nézel and Maule; at the triangular junction that follows immediately, go up a small street on the left. At the T-junction, turn left (there is a ‘No Entry’ sign on the right). At the next junction, carry straight on.
(5) At the T-junction, veer to the right and continue along this path, keeping the hedges on your right and ignoring the turnings to the right. You’ll come out onto Route de Montgardé.
(6) Turn right and carry on straight ahead, crossing a roundabout and passing a secondary school on your right. At the T-junction, turn left and ignore Rue des Palmiers. Just after the bus stop, cross Avenue de la Division Leclerc at the pedestrian crossing, take the path on the right, then turn left in front of a block of flats with two stairwells (4 and 2). Go through a gate and continue straight ahead along Allée du Haut du Parc until you reach a high-voltage substation.
(7) Turn right and, a few metres further on, after a pedestrian crossing, take a path on the left and continue left to arrive straight away in front of ‘La Maison de Tous’. Turn immediately right to walk alongside a long block of flats. At No. 35, with your back to the building, cross Rue du Belvédère and its car park to enter a park, then continue along a path to the right, keeping the playground on your left. When you reach another block of flats, ignore the two paths on your right (one in front of and the other behind this block). Carry on to the right and, just before the car park, turn left onto the tarmac path, which will give way to a footpath. Walk downhill until you reach another block of flats.
(8) Carry on to the left towards a flight of steps. When you reach the street, turn slightly left, walk past a small building and continue to the left for a few metres.
(9) Cross Rue de la Coopération at the pedestrian crossing to enter a park (wooden gate), which you’ll cross to the left towards the church. Then take a cobbled path and turn left in front of the town hall (marked by a striking tree).
(10) With your back to the town hall, cross Place Jean Monnet and walk past the church to turn left onto Grande Rue. Walk alongside the Château du Vivier, turn into the first street on the left and continue to the Théâtre de la Nacelle (S/E).
