(S/E) Head west towards the basilica for a tour of the interior. Go around the building on the left. Return east towards the school. Before the school, follow the street "Route de Bergerandière" to the left. At the next intersection, you will reach an area of houses.
(1) Turn right and continue straight ahead through the residential area. The road turns sharply to the left. After the last house, the road becomes a grassy path. Follow this grassy path through the meadow, ignoring a path leading off to the left. After Les Mouilles, you will reach a road near some buildings.
(2) Take the road going up to the right at a right angle. Walk alongside the buildings. Ignore a path coming from the right of the Epinouse chapel (option to go to/return from the chapel). You will reach a crossroads at an elevation of 495 metres.
(3) Turn right onto the road going up to the left and walk alongside a house. After 200 metres along the edge of a walnut grove, take the grassy path turning right towards the south-east in the direction of the Madonna statue and the orientation table. After admiring the views, retrace your steps back to the road. Follow the road to the right until you reach the next houses 700 metres away at an altitude of 517 metres.
(4) Turn right between the houses and reach a dirt track. Ignore a path going up to the left.
After a meadow area, you will reach the forest, which curves to the left. The path is marked in red/yellow here. Cross a deforested area with buildings on the left (at the time of writing, herbs were being grown here).
(5) The path climbs then descends in curves to the right then to the left and leaves the forest to reach walnut groves. At Landan, turn left and walk flat between the walnut trees. Cross the forest again, climbing then descending in curves to the right then to the left towards Les Amandes. Reach a road near the village of Chantesse.
(6) Follow the road to the left for 100 metres, then take a path to the right, marked in red and yellow, leading into the forest. (Here you can take a detour to the pond on the right.) After 700 metres, on a slight slope, join a path coming from the left.
No markings
(7) Take a hairpin turn up a path to the left. You will reach a road at a hairpin bend. Follow the road to the right. Ignore a road leading off to the left and follow the bend to the right. The road then curves to the left towards some houses. You will reach a crossroads with several roads at Le Rif.
(8) Take the D210C road to the right for 20 metres, then take the road on the left to continue on flat ground. After 50 metres, ignore a road going uphill to the right. When you reach some houses, take a short grassy path on the right that leads to a road. Take the road uphill to the right. Go around a house on the left. Reach the forest and, following a curve to the right, arrive near the Grand Champ buildings opposite, but do not reach them.
(9) Take the sharp left turn. After 400 metres, you will arrive near the houses on the left, where the path becomes a road and you will rejoin theGRP® Tullins-Vinay.
Red and yellowGRP® markings
(10) Follow the road straight ahead, ignoring the road going up to the left, which is theGRP®. Near an urbanised area, you will reach a crossroads and a road coming from the right (the D201) and continue downhill to the left. After 100 metres, ignore a road coming from the right. You will reach the Col de la Cassière and a crossroads near the houses.
(11) Continue straight ahead uphill on the "Chemin du Plancher". At the top, take the path on the right opposite a gate, ignoring the road leading off to the left at elevation 524. The markings here are still red/yellow. Cross the meadow, then continue downhill until you reach the forest. Please note: 100 metres after entering the forest, turn left through a gate.
(12) Cross the meadow, then enter the forest and continue almost straight ahead, ignoring the paths on the left and then on the right. Near the buildings and elevation 454, you will reach the road. Follow it straight ahead, ignoring a path and then a road on the right. The road curves to the left and then makes a hairpin turn to the right where it meets a road coming from the left at Les Endeyés.
(13) Take the road coming from the left. Walk past the house on your right. 20 metres after the house, turn right downhill into the meadow and walk along a fence. Join the road and follow it to the left. Please note: 400 metres further on, take a very small path climbing steeply to the right up the road embankment.
(14) Follow the path up to the right and then to the left to reach a road. Cross the road and take the path almost opposite on the left. After a few bends, you will reach and walk along the fence of a house. Reach the cemetery and the village level.
Walk along the cemetery on your left. Reach and visit the Bon Rencontre chapel. Continue opposite the basilica and at the corner of the retirement home, turn right and return to the starting point
(S/E).
Beautiful route with no difficulty in finding your way with the Viso trail. Nothing to complain about, perhaps a few too many small tarmac roads, but with no traffic.
