Parking: Domaine départemental du Bois Chardon, on the D448 (formerly N448) at the entrance to Draveil (Champrosay district), coming from Soisy-sur-Seine.
The entrance is almost opposite the Draveil entrance sign, on the left-hand side. Conversely, when travelling towards Soisy, it is on the right-hand side next to the Draveil exit sign.

Pass the Carrefour des Dames and continue to the Carrefour Pacôme. Turn left onto the Route forestière de Draveil until the next crossroads, in front of the Ermitage. Turn right onto the Route forestière de l'Ermitage and walk along the wall to the last entrance on the right (closed), which used to give access to Nadar's beautiful house, visible behind the gate (*).

(4) See the beautiful chapel and then the castle. Continue straight ahead on Rue de l'Ermitage. Cross Rue du 8 mai 1945 on the right and 80 metres further on, on the right, you will find the entrance gate to Parc du Grand Veneur.
Enter the park. Walk through a row of trees to find the path on the left that runs parallel to the street. Follow it around the large clearing before descending into the woods and reaching a cave with a spring, typical of the decorative features of the period. Continue downhill along the small stream to the ponds in front of the Château du Grand Veneur (*). Go around the pink castle on the right to reach its courtyard façade.
(5) Walk along the façade to the end and arrive in front of the annex building in line with the château. Go through the gate to the right of the annex and find the path that goes around the estate, and take it almost in line with the previous annex. A few metres further on, take the path on the right that leads down to the white château of the new town hall. Leave the park through the passageway and gate on the left as you descend, then follow the street that passes to the left of the château. Go around it to reach the pedestrian square in front of the château/town hall (*).
(6) Cross the square towards the restaurant "Le Cosy", then cross Rue Notre Dame _ caution _. Walk along the church to the left, along Rue de l'Église. Cross the square in front of the church to reach Rue Galignani, turn left, then cross Boulevard de la République and continue opposite, Avenue Chevalier, until you reachthe first crossroads.

(9) Continue straight ahead along the river. Pass under the Château de Trousseau, which overlooks the valley. Cross the small Ruisseau de L'Écoute s'il Pleut (*). Immediately afterwards, pass in front of the electrical substation and the sailing centre at the exit of the pedestrian zone.
(10) Turn left onto Chemin de la Sous Station. Pass under the railway line, then climb the few steps on the right to reach Étang de Ris-Orangis (*). In front of the pond, follow the footbridge on the left that runs along the water and goes around the pond on the left. At the end, turn right to walk along the short western side of the pond. Roughly halfway along the short side, turn left onto Allée du Lac through the new neighbourhood (*). Arrive under the glass roofs and follow Passage de la Grande Halle to the right. Arrive at Rue Freyssinet (*) and turn left. Pass at the foot of a green-tiled building and find Rue de Seine, which continues to the right under the railway line.
(11) Turn right into the underpass to reach the banks of the Seine. Turn left towards the bridge. Pass Rue de la Malterie (on your left) and some old buildings, the last of which has been repainted pink (*).
At this point, take the pedestrian crossing on the right towards the Seine to pass under the bridge. On the other side, climb the stairs to reach the bridge and cross the Seine without changing pavements. At the other end, go back down the stairs to reach the banks of the Seine.
(12) Walk along the Seine on your right with theGR®®2(white and red markings). Walk along the sports fields (*) and the old Saint-Victor port at the end of Rue Sainte-Anne.

After a curtain of trees, leave the markings and turn right into the clearing parallel to the Seine, passing under the high-voltage power lines. Towards the end of the clearing, climb up to the left. Cross the bridge and walk along the wall of the Bois Chardon allotment garden. At the top, follow the wall to the right. Opposite the gate, climb left towards the car park, passing to the right of the Trésor fountain (S/E).
