Start from the car park on the D21 in Crissay-sur-Manse. Coming from Saint-Épain, the car park is on the left shortly after the sign indicating the entrance to the village.
(S/E) From the car park, take the departmental road on the left, then left again onto the path leading to Crissay church.
(1) From the church, return via Rue du Puits Auger to the main road. Cross it and continue straight ahead, uphill on Rue de la Porte Bigot. Ignore the various turnings.
(2) About a hundred metres before the forest, turn left at the hairpin bend, then take the first road on the right towards Avon-les-Roches and La Jolivière.
(3) Leave the road towards La Jolivière after a few dozen metres and take a grassy path on the left. This path meets a road shortly after a small wood.
(4) Turn left onto the small road going downhill. At the crossroads, turn right, pass the wash house on the Quelle, then ignore the side roads until you reach Avon-les-Roches.
(5) At the fork, keep left on Rue du 8 Mai, downhill, until you reach the church. Then take the main street, Rue de Feunet, on the left, and finally the first street on the right, Rue de la Poste. Pass the wash house and the sports facilities. Leave the street leading to the campsite on your right.
(6) At the crossroads, follow the signs for Jautrou on the right.
(7) Pass the path that runs alongside a barn on your left, just before the wash house where the road begins to bend to the right. You will need to come back here, but before continuing on your way, a short detour to the village of Jautrou is a must. To do this, take the right-hand bend and then turn left under the porch to reach the village. Retrace your steps.
(7) Walk along the barn, then cross what appears to be the entrance to a farm, marked by two posts, and take the grassy path that climbs slightly to the right. This is followed by a narrow lane that turns left at La Jouardière.
(8) At the crossroads, turn right onto the grassy path.
(9) The path eventually meets a road, which you take to the right. Leave this road after about 50 metres and take a lane on the left. Turn right at the junction with a crossroads towards Le Puy Chauveau. A small road follows the path as you approach the hamlet.
(10) Turn left at the intersection and then immediately right towards La Touche Hulin. Ignore the first intersection with a path.
(11) At the next crossroads, leave the tarmac road and take the lane on the left towards Les Roches Tranchelion, then keep right at the fork after about 50 metres. Ignore the various turnings and follow the busiest lane, which is mostly stabilised.
(12) Keep right at the junction with Route des Hautes Roche in a bend with a side barrier. This road runs alongside a pond and then curves to the right, passing numerous caves. Route des Hautes Roches eventually joins another road, which you follow until it intersects with a cross road shortly after a picnic area near a wash house.
(13) Follow the signs for Roches Tranchelion on the left, then for Collégiale les Roches, turning left again onto an uphill path that leads to the ruins of the collegiate church. A grassy path takes you closer to the ruins, then back to the main uphill path, first along the edge of the forest, then into the forest.
(14) Keep right at the fork, then right again to join a forest path. Pass the first path on the right.
(15) At the crossroads, turn right downhill. The forest path eventually joins a small road.
(16) At the intersection, turn left to go around the Carroi de la Grange (a public square in the Middle Ages), now a mound covered with vegetation. Pass the first turn-off on the right, then turn right onto a track leading to Puy aux Bœufs. After the hamlet, the lane gives way to tarmac and then intersects with the D21. Turn right onto the departmental road and proceed with caution until you reach the car park, the starting point of the hike (S/E).
