(S) Park in front of the church of Saint-Pierre-de-Chandieu. Walk past the notary's office to reach the east side of the church. Walk a few steps south, cross the road and turn left at the three-way junction. At the intersection, continue uphill to the right (Chemin du Sablier). The road begins to curve to the right.
(1) Admire the view, then take the small grassy path down to the left. Ignore a path on the right and continue to an intersection after a house. Turn right onto Chemin de l'étang. Continue straight ahead.
(2) Shortly after a shed and a horse sign, take the path on the right. Continue right on the path that climbs into the forest. Further on, you will come to a field. Keep following the path that takes you to Chemin des Crêtes (paved).
(3) Take this small road on the left to descend to a roundabout.
(4) Turn right and then, immediately after, take Chemin de Chantemerle on the left. At the fork, turn right. Follow the road downhill, which becomes paved further on. At the crossroads, continue straight ahead until you reach the entrance to Rajat Castle.
(5) Turn left and immediately right. Just after the fork, follow the path on the right that goes around the park in a heart shape (a romantic gift from a bourgeois Lyonnais to his beloved wife). Admire this beautifully maintained château.
(5) Back on the road, as you leave the estate, cross the road and take the path opposite, slightly to the left. You will then follow the departmental boundary between the Rhône and Isère rivers. Be warned, the climb is long and difficult. Further on, you will reach some houses and the path becomes a road. Continue to a four-way intersection.
(6) Turn left towards "Les Oranges". At the entrance to this hamlet, take the path that descends to the right and ends in front of a beautiful private lake.
(7) Leave the lake on your right and continue straight ahead on the path. At the next intersection, turn left. At the junction with Chemin des Oranges, continue straight ahead. At the next intersection, take the road on the right. Further on, it turns right and then left to join a road. Turn right to come out onto another road. Continue left until you reach the intersection with a path, shortly after the entrance to the village of Heyrieux.
(8) Turn right onto Chemin de Périquet. At the fork in the woods, continue in the same direction, taking the path on the right. Ignore a path on the left. Shortly after, cross the Ozon. Immediately after, ignore a path on the right. Further on, the path widens at Maison Prat. Continue straight ahead until you reach a paved road. Continue straight ahead and ignore a path on the right.
(9) Turn right into a small housing estate (Impasse des Châtaigniers). At the end of this road, turn right in front of the last house and take the path on the left. Further on, turn left and then right onto the path. You will eventually come to a wider path. Go down a little to your left.
(10) Just after this, turn onto the path on the right before the stream. You will be following a high-voltage power line. Continue straight ahead and pass under the power line. Just after this, ignore a path on the right and continue straight ahead until you reach Ozon.
(11) Turn right and follow the stream. Further on, you will find a small wooden bridge that will take you across the Ozon without getting your feet wet. The small bridge may have been washed away by flooding, in which case you can cross the Ozon using one of the many fords with well-placed stones. Continue straight ahead to reach the Combe Pelouze landmark, at the intersection of several paths.
(12) Take the left-hand path and climb up to a paved road. You will reach some houses.
(13) Immediately take the path on the right alongside the house. Continue straight ahead until you reach a paved road.
(14) Turn left heading west and continue straight ahead at the next two intersections to reach a small Nature and Wildlife viewpoint, marked with a cross, on your left.
Continue along the road for a few metres until you reach a bus stop.
(15) Take the small path on the right that runs alongside a property. It descends, is narrow but widens at the bottom of the slope and leads to the end of a street.
(16) Turn right onto the path that joins another street. Continue north on Chemin Sous-Vignère until you reach the church, your starting point (S/E).
