Park in the car park in front of the church in Champier, a small village halfway between Lyon and Grenoble, along the D1085.
(S/E) Look at the front of the church and take the alleyway that runs alongside it on the right. Pass the cemetery on your right. At the stop sign, take the dirt road opposite, to the right of the containers. You will come to a path, which you take to the right. You will arrive at the sign "Vernondière - 493m".
(1) Turn right. You will come to a street; turn left. Once you have passed the sports stadium, turn right. Cross the D1085 and follow it on the left. Turn right onto Chemin des Serves, which climbs towards the hill (yellow markings). It goes around the hill and leads to a pretty valley. A road joins from the left, but continue straight ahead.
(2) When you reach a path that climbs steeply to the right, take it, following the yellow markings (this is the steepest part of the walk). At the top, it leads to a T-junction. Turn left. When you reach some farm buildings, take the small road on the left. It zigzags twice. Leave a small road on your right.
(3) When your small road turns 90° to the right, take the dirt track that continues opposite. You will arrive at the sign for "Le Vauchesse - 555m".
(4) Continue straight ahead. You will enter a hamlet, passing a narrow street on your right. At the crossroads that follows almost immediately, turn right onto the D502, which connects Champier to Châtonnay.
(5) Cross the road and continue straight ahead to reach the hamlet of Gerbuat.
(6) Make a left/right zigzag. When you reach a power line, continue along the path in front of you. After passing under the power lines, you will see the sign for "Le Vernay - 560 m".
(7) Turn right to immediately reach the D1085.
Be careful here the crossing is dangerous. The 90 km/h speed limit is not really respected here and there is a bend to the right and a hill to the left. Visibility is quite poor. Be very careful of children (among other things).
Continue straight ahead (Chemin du Vernay). Then take the dirt track overlooking the houses on the left. At a T-junction, turn right (signposted "Plan Martin - 566m" - Flachères 2.7km). 100m further on, turn left, ignoring the grassy path that continues straight ahead. Continue under a power line. When your path branches off to the left, take the path on the right of the line, which climbs steeply. Further on, you will come to a small road. Take it to the right.
(8) You will pass through the hamlet of "La Grand Croix". At a fork in the road, take the right-hand branch towards Flachères (route de la Grand Croix). As you enter Flachères, take the left-hand branch at the fork in the road, which will quickly lead you to a "Stop" sign and the town hall. Cross the road and continue straight ahead.
(9) A little further on, on the left, you will see a sign for "Flachères - 600m". Pass the church (if you have chosen to start your walk in Flachères, you will join us here). Continue straight ahead, ignoring the streets on either side.
(10) When you reach the sign for "Château d'eau - 625m", take the right-hand fork (your path crosses the beautiful Gourand woods, but you can't go wrong, it's straight ahead). You will reach the Étang du Roujat lake.
(11) Turn right onto the road that descends (Montée du Cordier). When it curves sharply to the right and descends steeply, take the lane on the left to reach La Madone.
(12) At La Madone, enjoy the view over the Champier valley and the Liers plain. To set off again, go behind the chapel, on its right-hand side, and take the faint path that descends to the right. It returns in front of the chapel, below. At the end of the field, you will see the rest of the path (anti-motorbike barriers). Descend into the woods. Once at the bottom, walk along the cemetery opposite to return to your starting point (S/E).
