Park in the free car park on the edge of the D538 (Montée Saint-Marcel to Vienne) at number 51 (new building).
(S/F) Head down the D538 to Vienne town centre for about fifty metres. At the traffic lights, leave the D538 to take a slight right uphill along a small road (Chemin de l'Octroi Oest) towards the Pipet viewpoint and the Delay nurseries.
At the end of the lane, take Chemin de Pipet to the left towards the Pipet viewpoint. Continue on Chemin de Pipet for 400 m, then when borders the cemetery, slightly left towards the Pipet viewpoint. Go up to the viewpoint, enjoy the views over Vienne, the Rhône Valley and the Pilat massif.
Retrace your steps, and arrive at Rue Pipet, then continue on the right. Immediately after this, turn right at a right angle, and take a paved staircase (Chemin des Amoureux). At the bottom of the stairs, cross the D538 (Montée Saint-Marcel), follow the small road opposite that goes to the right (Montée des Tupinières).
After a 400 to 500 m climb, just after number 23 (2), follow a hairpin turn right and take the first small street that descends sharply (Montée Beaumur). Downhill, the street takes at right angled turn to the left and along the old odeon forum.
Turn left at the first street corner to continue following Montée Beaumur (just after the opening of the wall surrounding the forum (works)). At the next junction, turn slightly left to take Chemin Coupe-Jarret.
Continue to head uphill, pass the hairpin bend on the left, 25 m away, completely turn around in a hairpin bend on the right to take the tiny lane uphill called Grapillat de Coupe Jarret (3).
Upstairs, reach Chemin Coupe-Jarret and follow it for 20 metres, then immediately turn right on Chemin de la Corniche (4). Continue on this path with its changes of direction and slopes, and its beautiful views of the Rhône valley to the south and over the Pilat massif.
At the top of the Chemin de la Corniche, at the crossroads, turn right onto Chemin des Murieux. At the next junction, turn to the left onto Chemin des Centaures. Follow this slightly tortuous path that makes a wide curve to the left. At the end, at the intersection with Chemin de Charvanay, turn right and follow this road for 200 m to reach Chemin de Coupe-Jarret ahead. Pass the Viennoise horse club of Les Charmilles.
Continue on this road for 250 m and take the first left, on Montée des Grands Prés (5). At the next Y-junction, follow the main road on the right (Chemin de Beauregard), which offers sweeping views of the Viennoise hills for almost 1 km.
(6) Take the first right (dead end), Chemin de la Musardière, for 100 m. Where the paved road ends, continue straight through the path downhill ahead. At the bottom of the road, turn to the left on Chemin des Cirelles and follow it to its end.
At the end, turn right on Chemin de Beauregard (7). Follow it for about 500 m, then take the first road on the right, Chemin Passardière (8). Head down until you reach the D538 (Montée Saint-Marcel). Turn left (note that there is only one pavement on the right side of the road) and down to find the starting point (S/F).
