Start from the Marais de Reilly car park, Rue de la Vignette in Reilly.
(S/E) From the car park, set off with your back to the pond, following the Ruisseau du Réveillon. Just after the wash house, turn left onto Rue du Réveillon (D6). Pass the Chemin du Clos de Magny on your left, then, about fifty metres further on, climb the steps on the left leading to the Church of Saint-Martin in Reilly.
(1) Return to Rue du Réveillon and turn right to follow the Chemin du Clos de Magny after about 600 metres. It opens out onto a field and turns to the right.
(2) Continue along this path, which is known as the Chemin de Boubiers. Starting at the edge of the woodland, it enters the forest, turns right then left, and comes to a junction with the Allée des Moutons.
(3) Ignore the path leading off to the left and follow the Chemin de Boubiers straight ahead, through the woodland for about 1.5 km, until you finally reach a crossroads.
(4) Pass the return path on your left, turn right as you leave the woods and continue to the end of the path, where you’ll reach a T-junction in the village of Boubiers.
(5) Turn right; after about a hundred metres, the path bends to the left. Immediately afterwards, turn left onto the Chemin des Jardins, then right onto the Chemin du Château d’Eau. Cross the Rue du Chêne and take the Rue du Cul de Sac opposite. At the end of the street, turn left and, immediately at the Fork in the road, keep to the right. Join Rue du Billoy (D121).
(6) Cross it, pass the war memorial and turn immediately left onto Chemin des Aviateurs. The path winds round a wood and joins Rue du Beau Chenaux; follow it to the left until you reach Rue du Poirier Vincent.
(7) Turn right and follow this street until you reach a small roundabout. Take the first street on the right (D121) for about 200 metres. At the sign marking the exit from Boubiers, take a grassy path on the left, heading due north, which leads to the Church of Saint-Lieu-et-Gilles.
(8) Turn left, with your back to the church, and walk for about thirty metres; let the road branch off to the left and continue straight on along a track suitable for vehicles. Turn right, heading due north, onto the first track which, at the bottom of a fairly steep descent, joins the junction you passed on the way there.
(4) Turn right into the woods and follow the outward route in the opposite direction. You’ll come back to the junction with the Allée des Moutons that you passed on the way out.
(3) Turn right onto the Allée des Moutons, then take the first path on the left (Chemin du Marais). The path, which is initially straight, eventually winds around the ponds before joining the Réveillon.
(9) Cross a small bridge on the right, go round a final pond and return to the car park (S/E).
