Departure from Sainte-Croix-sur-Aizier, from the car park opposite the playground on the road to Sainte-Croix (after passing the church crossroads).
(S/E) Leave the playground on your left, heading north-east, then turn left immediately. Continue straight ahead, take the third road on the left and, after 200 metres, leave the road and continue straight ahead along the path into the forest.
(1) Turn right and continue downhill on a marked path overlooking the old Aizier road in the forest. Ignore a path on the right and continue downhill until the path joins the road. Follow the road to the right until you reach a stop sign at the entrance to Aizier. Turn right and admire the thatched cottages on either side of the road.
(2) You will rejoin theGR®23(red and white markings), which no longer follows the route shown on the IGN map. Turn left when it passes behind the church and follow a narrow path to the Seine gravel path. It crosses a picnic area, then follows the Seine on your right to Vieux-Port.
(3) Turn left onto Rue Martey, which joins Grande Rue, then turn right. Follow this street uphill and admire the Norman houses and their magnificent gardens.
(4) At the edge of the village, you will come to a crossroads with signposted paths. On the right, the Chemin des Douaniers descends towards the Seine and crosses woods. This formerGR® trail has been closed because the cliff has become dangerous. Do not take the signposted path on the left that climbs back up towards the south-east, but continue to follow the road (D95).
(5) Leave the path on your right and follow the road that climbs through the woods and curves sharply to the left before reaching a fork in the road.
(6) Turn right at an acute angle onto the small road called Val de la Briqueterie, which is a dead end. Go down to a crossroads serving a few houses. Follow the path on the left that runs along the Seine on the cliff (GR®23). You will see the chimney of the old brickworks on your right. Avoid going up the Court Val by continuing to the right along the marked path. Follow theGR® which stays on the cliff, in the forest above the Seine, then leaves it by going up to the left along the Val de la Haye (a long, steady climb).
(7) When the trail joins a path, take it to the left, then turn right (avoid a path that descends towards the Seine). The path runs along the edge of the forest, below a farm, then comes out onto a small paved road (Rue de l'Oraille), which you take to the left.
(8) At a triangular crossroads, take the second left (Rue de la Sablonnière). The road turns right and continues along a path. You will come out onto the D95 going up from Vieux-Port, which you take to the right for a short distance. At the next crossroads, turn slightly left onto Rue aux Hêtres, which crosses the hamlet of Vaucorne in a straight line.
(9) Turn left onto a marked path between the trees. At the first crossroads, go up to the right (leaving the marked path that goes downhill on your left). Continue along Chemin Perrey (tarmac) until the next crossroads.
(10) Turn left towards the water tower, then turn left onto Route de la Chapelle (an old Roman road). Follow the small road downhill for over a kilometre until you reach the forest and a junction with a marked path.
(11) Take the path on the right that gradually descends into the forest until you reach a stream. After the stream, go up to the left, then cross the D139. Continue along the path opposite, which then joins the road from Aizier to Sainte-Croix.
(12) Turn right (leaving theGR®) until you reach the church of Sainte-Croix. At the crossroads after the cemetery, turn left to reach the car park (S/E).
