Departure from Us station (Transilien line J, on the section between Paris-Saint-Lazare and Gisors). Take the only exit, Rue de la Gare, on the side of Track 2 (Gisors-Paris direction; if arriving in the opposite direction, Track 1, cross the tracks at the designated crossing, observing the traffic lights).
Yellow + red and white signage
(S/E) When you leave the station, turn left and follow Rue de la Gare to the end. Then turn left and cross the railway line at the level crossing. At the roundabout, follow Rue Jean Jaurès opposite, which goes up towards the church. At the end of the church, turn right onto Rue Henri Clément, walk along the church on your left and continue straight ahead.
Yellow markings
(1) At the crossroads, turn left onto Rue de la Libération (D66). At the next crossroads, take the second left, Rue de la Chaussée Jules César, which goes uphill. The tarmac quickly gives way to a shaded path. Cross a perpendicular path and you will come to a crossroads in more open terrain.
No markings
(2) Continue straight ahead on a good gravel path that starts along a fence on the left-hand side (ignore the yellow arrow inviting you to follow a very grassy path on the right). Note the cemetery some distance away on the left, then climb gently along a hedge. At the top of the hill, ignore a path on the left and continue straight ahead (south-west).
Yellow markings
(3) At the T-junction, turn left onto a wide path (an old Roman road called Chaussée Jules César). Cross a small road and continue straight ahead. Descend, walk along a wood on your left, then climb back up.
(4) Note a shelter on the right and continue along the path, which becomes grassy. Further on, along a wood on the left, the path narrows and makes a sharp turn to the left. Climb gently between two hedges and, once the terrain opens up again, continue along a wider path.
No markings
You are now back on theGR®1, but the terrain is unsuitable for markings.
At the three-way junction (elevation 102), turn left downhill (leaving thePR® trail going uphill to the right).
Yellow markings
(5) At the next crossroads (elevation 85), continue straight ahead on a slightly downhill track (you will find markings further on). Ignore a path coming from the left, pass under a power line, enter Ableiges via Rue du Dr. Scwheizer and pass a metal cross on your right. At the stop sign, continue straight ahead onto Rue du Maréchal Leclerc and cross the railway line at the level crossing. Then cross the two branches of the Viosne river.
(6) At the T-junction, follow the D92 to the right towards Cormeilles-en-Vexin. At the corner of No. 2, turn left onto Chemin de Cormeilles and climb up along the wall on the left-hand side. Continue along a very steep section of tarmac. You will come out onto a road (D190 on the map) and follow it to the left (take care, as the verge is very narrow).
(7) Shortly after a white two-sided sign, turn left onto a wide dirt track that quickly becomes grassy. After a left-hand bend in the track, note the view of the village of Us and its church. At the next intersection, turn sharply right and follow a gravel track lined with walnut and cherry trees on the left-hand side. At the gate on the right-hand side, continue straight ahead on a grassy path.
(8) Ignore a path on the right leading to a field and take a path at the edge of the woods. Follow this narrow path for a long time, flanked by dense vegetation. After the end of a hedge on the right-hand side, continue along the faint path at the edge of the field (on your right). At the corner of the field, continue for a few dozen metres through the undergrowth. Continue again along the edge of the field and go around the Bois de la Grande Brosse on the right.
(9) Find a decent path, although it is quite overgrown, and continue along the woods on your left. In open terrain, ignore a path on the left and head west between the fields (view of the turrets of the Château de Dampont). Cross an old tarmac road (chains) and continue straight on to the D28.
(10) Follow the road to the right, preferably on the left-hand side (take great care, as the road is busy and the verge is narrow; on a short section, you can walk behind the safety barrier). Walk slightly uphill, following a fenced wood on your left.
(11) At the crossroads (C3 road on the right), turn left onto a wide gravel path. Follow a hedge on your left. Then pass between two hedges and descend along the wall of the property on your left. At the bottom, pass through a forest gate and you will come out onto a small road.
Yellow + red and white markings
(12) Turn left and cross the hamlet of Dampont. Cross the Visone, cross the railway line at the level crossing and go uphill.
(13) At the stop sign, continue straight ahead on the road (good pavement on the left-hand side) and ignore the side streets on the left. At the next stop sign, continue straight ahead into the village of Us.
Yellow markings
(14) At the corner of No. 6, turn left towards the stadium. Cross the Viosne again (note the wash house and picnic table on the left).
(15) Continue straight ahead and cross the railway line one last time. Go uphill, passing a large farmhouse on your left (dovecote). At the crossroads, take the first right, Rue des Tilleuls, and follow it along a good path on the left-hand side, in the shade of the lime trees. Cross the Viosne river one last time. Just before the railway line, turn left and follow the street to the station (S/E).
From 8 to 9, the trail is impassable. Follow the edge of the field and the woods to reach point 9,
