You come to a large grassy and sandy car park. Cut diagonally across the car park to join Route du Luxembourg, with a rather steep yet short gravelly downhill section. If you hear the racecourse loudspeaker, then you’re headed in the right direction. After the racecourse, approaching a clearing, bear slightly left onto Route du Sport, passing behind a car park. At the end of Route du Sport, turn right onto Route du Mont St Germain. At the end of this road, cross the D606. Be careful crossing this very busy secondary road. On the other side of the road, continue straight on a few metres further, then take the first left: Route de la Deuxième Tête, which will lead you to Route de la Butte St Louis. At the first crossroads, turn right onto Route Victor, where you might meet a few convivial cuckoos. At the end of the road, turn left onto Route des Ventes Bouchard. Further on, follow the second road on the right: Route des Larmières. You come to the old Route de Bourgogne, which you carefully cross via the pedestrian crossing. Continue along the bike path on the left to enter Bois-le-Roi. At the first intersection, continue straight on along the bike path. At the roundabout, turn right onto Avenue de la Forêt. Continue straight on along this road until the passage under the railway; the Bois-le-Roi railway station is just around the corner.
