The starting point is in the car park of the Stade des Violettes in Darnétal, Chemin du Four à Chaux (not far from the waste collection centre).
(S/E) As you leave the car park, take the path on the right which climbs slightly to the edge of the forest and then enters it.
Ignore two paths that branch off to the right and continue until you reach a fork.
(1) Continue left (Chemin du Pont Bleu) until you reach the second fork.
(2) Turn left again to reach a T-junction at the edge of the forest.
(3) Turn right onto the path and continue straight ahead until you reach the entrance to the village of Roncherolles-sur-le-Vivier at a T-junction (about an hour's walk).
(4) Follow the road to the right until you reach the intersection with the path that passes in front of the village school. Take this path and, just after the school and library, take the road on the right that passes in front of the church and town hall.
(5) Then take the small path that branches off to the left opposite the town hall (Chemin des Murets). At the end of the path, take the road on the right for about 100 metres (Rue du Carrouget) and turn left onto Chemin du Vallon, which continues straight ahead on a small path leading to Rue du Vieux Château.
(6) Take this road on the right and continue straight ahead for about one and a half kilometres until you reach a fork between the road that continues and a path.
(7) Turn left onto this path and cross the fields until you reach a road that leads to the village of Préaux at an intersection (about a 30-minute walk).
(8) Turn onto the farm track on the left and continue straight ahead for a few kilometres until you reach the forest. At the entrance, continue along the track, ignoring the track on the left which is closed by a barrier.
Cross the forest until you reach a path overlooking the village of Fontaine-sous-Préaux (Chemin du Mont Roty). Continue along this path down to the village and join the D47 at the bottom (about 30 minutes' walk).
(9) Cross it to pass in front of the fountain and go up along the Route de la Fontaine. A little further on, you will reach the intersection with the departmental road
(10) Take this road on the left, which passes under the railway bridge.
(11) Immediately afterwards, turn left again. Climb to the top of this lane (be careful, it's quite steep) and continue along the path that enters the forest, staying more or less on the edge. Continue straight ahead until you reach theGR®25Cat a fork.
(12) You can turn left if you don't want to go through the centre of Saint-Martin-du-Vivier and rejoin the path you took on the way there.
Go straight down towards the road and arrive at Saint-Martin-du-Vivier. (about 1 hour's walk).
(13) Cross the railway line (separation from theGR®) and continue straight ahead to the D47, which you will also need to cross. Continue along Rue de l'Ancien Presbytère, following the course of the Robec to the charming church square. Join the D47 again. Turn left immediately afterwards onto Rue Bouvier.
(14) Cross the Robec again and turn right, still on Rue Bouvier, and continue straight ahead until you reach the path at the end of the street (before the bend) which runs behind the village school.
(15) At the end of this short path (a few metres), takethe GR®25Con the left. (approx. 10 to 15 mins' walk); Reach the forest and cross it until you return to the village of Roncherolles-sur-le-Vivier. Continue straight on along Rue des Trois Fermes.
(16) Turn right, still on theGR®, onto Chemin des Pépinières (before reaching the school). Walk past the sports fields to the road and turn left for a few metres until you reach the fork you passed on the way there.
(4) Turn right and follow the path in the opposite direction to the one you took on the way there until you reach the crossroads of thefirst loop.
(3) Follow theGR® straight ahead. Be careful, it's quite a steep descent at the edge of the forest, but with a beautiful view of Darnétal. Join a road at the bottom.
(17) Continue straight ahead until you reach the D43.
(18) Turn left onto Chemin de la Côte Pigache. Pass the Darnétal waste collection centre before reaching the road that leads to the car park just to your left (about a 45-minute walk). (S/E).
Once you're back at the starting point, take some time to stretch or watch a football match at the Violettes stadium for a well-deserved break!
