The trail starts at the edge of the woods, about 50 metres after Sorel Castle.
(S/E) Facing the forest, take the path on the right, then turn left onto the lane running along the slopes of the Eure (southbound) for 600 metres, then turn left (eastbound) and take a path on the right after 450 metres.
(1) Follow this path, which crosses the road (D21.7) after 200 metres, until you reach a crossroads (orange marker) 260 metres further on.
From the crossroads, turn right until you reach a junction, then take the second path on the right and continue along the path on the left for 400 metres until you reach theGR®®22on the hillsides overlooking the Eure.
(2) Continue along theGR®®22(marked white-red) for 800m until you reach a fork near a gate in a wire fence.
(3) Turn left (do not go down to the right), then keep to the right a little further on to reach a crossroads. Take the second path downhill (eastbound) and arrive further down on the Route des Grosses Pierres.
(4) Turn right (or continue straight ahead off the trail to rejoin the path 100 metres further down on the left).
Then go up the path on the right (north-east) for 100m to a fork where you leave this path and take a narrow, steep path through the heather. Go up this very narrow path, which is quite steep at the start, to a crossroads near a small pond about 180m away.
Continue along the path on the right, passing in front of the pond (south-southwest) and descending to the Château de la Robertière crossroads (information panel about the ruins of La Robertière at this crossroads). Distance from the pond to this crossroads = 410m.
(5) From the crossroads, leave theGR®®22by taking the path on the left (white-red cross on a tree) heading east.
Keep left further along the path leading to the Carrefour de la Robertière junction (from the castle ruins junction to the Carrefour de la Robertière junction = 600 m).
(6) From this large crossroads, continue straight ahead until you reach the Carrefour de la Gratture au Loup crossroads 550m away (signpost).
From this crossroads, take the 4th path on the right (north-north-east) to a large driveway (Route de Marcilly, 570 m).
(7) Cross this large driveway and take a very narrow path on the left just behind the barrier opposite (the path runs parallel to the large driveway).
Continue along this path, passing the Mare aux Corbeaux (at 750m) on your right, then continue after a crossroads and turn right at another crossroads (in the heath) to head towards a riding centre (north-north-east) and turn left onto a bridle path until you reach a crossroads near the riding centre.
(From the Mare aux Corbeaux and the equestrian centre = 850m).
(8) From there, continue in the direction ofthe GR®®22(white-red markings) to reach a large lane, which you take on the right (Route des Meuniers) heading north.
(9) After 600m, take a barely visible path on the left and keep to the right at a fork further on to reach a road (D21.7).
(10) Cross the road and continue straight ahead, leaving the Mare de Sorel on your right, until you reach the Château de Sorel (S/E).
