Park your vehicle in the large car park at Place du Château de Roussillon in the centre of the village.
(S/E) At the eastern end of the car park, at the crossroads, follow the Montée de la Yette almost opposite, which is steep at first and then flat.
(1) At the T-junction, follow Chemin du Couvent to the left and then take the first road on the right towards Les Merciers. Ignore a road on the left and continue through a sharp left-hand bend, leaving a dirt track on the right.
You will reach a dirt track (Chemin des Perdreaux) curving to the right. Cut across Chemin des Chasseurs and continue straight ahead, then cut across Chemin de la Forêt and continue on Chemin des Perdreaux until you reach a road.
(2) Follow the road to the right for 150 metres, then turn left after the orchard. After 150 metres, turn right towards the farm buildings and you will arrive at Chemin du Moulin.
Follow the road downhill to the left to reach the ford over the Sanne, which you cross via the footbridge. Shortly afterwards, opposite the house at Le Moulin, turn right at a right angle onto the dirt track. Further on, ignore a path leading downhill to the right and continue straight ahead on a slight incline to reach the road.
(3) Follow the road to the right, pass between the buildings and join the D131c, ignoring a road coming from the left. Follow the busy D131C road to the right. Be careful to walk on the hard shoulder.
After 300 metres, leave this road to the right and follow the road on the left (Chemin des Vaures) and, almost immediately, take the path uphill on the left. Ignore a path to the right and approach the D131C road again near a building.
(4) Follow the path perpendicular to the right, which is Chemin des Escarbots (not escargots!!). Pass under the high-voltage line, ignore a path coming from the right and continue to a crossroads.
(5) Cross the road and continue straight ahead towards the water tower. Ignore a road coming from the left and then a path coming from the right and follow Rue de Montailloud downhill. At the Rebatière crossroads (calvary), go straight ahead, skirting the buildings on the left. At the corner of the buildings, take the road on the left and cross it to walk on the right behind the row of trees.
(6) Take the first path on the right, cross the Pont des Moines and head towards the priory on the right. Walk along the left side of the priory (to admire the whole building, you can walk around it on the right). Follow the road uphill opposite, which curves to the left to reach another road at the top.
Turn right at the hairpin bend, follow this uphill road near the houses, ignoring all accesses to the left, and reach a forest area.
(7) At the edge of the forest, at an elevation of 222 metres, take the path on the left. Follow this good path in a straight line to reach a road and a residential area. Cross the road and follow Chemin des Moulins opposite, first through fields and then through a residential area. Continue down a steep slope, still in a straight line, to reach Rue Laennec.
(8) Follow Rue Laennec to the right and you will reach a main road. Follow this road for 30 metres to the right. Cross opposite Impasse des Pommiers and turn left onto the road going uphill (Passage Lecerf). At the end of this road, first turn right then left onto Rue Bossuet.
Continue uphill to the right and pass the church on your left. Between the cemetery and the church, there is a platform offering a beautiful view. Follow Rue Halle Vieille and pass under an arch, a remnant of the ramparts.
Before reaching the castle, turn right onto the descending stairs that lead to the monument and then to the castle. Arrive at Place de l'Edit and return to the starting point (S/E), leaving the castle on your left.
