The walk starts from the Jambles leisure area. Arriving from Givry, turn left at the Drain vineyard (small sign indicating the leisure area). On the other side of the village, pass the church and turn right (sign indicating the walk parking area).
(1) Climb the path alongside Agorespace and follow it to the left until you reach the first wash-house.
(2) Take the narrow path on the left. When you reach the road, turn left, then right, and at the bend in the road, follow the footpath on the left as it rises and runs alongside the old people's home. Turn right onto the road (Rue de Charnaille) and go straight on to Château de Charnaille.
(3) Make a U-turn, then take the road to the right (Chemin du Grand Ru), which leads to another wash-house (on the left, below the road beside a house). Follow this road to the next junction. At the house and hydrant, turn left down this street (Rue du Chapitre).
(4) When you reach a square with a cross under a tree, turn left into the next street and head for another cross. Behind the cross is a wash-house (dry when I passed). At the cross, take Rue de la Côte Chalonnaise towards the school (signposted) and turn right at the first Junction (Rue du Quart Berry).
(5) At the school, turn left onto Montée de Brochon.
(6) When you reach the top of Brochon, you'll pick up a PR® signposted in yellow. Turn left and follow it down to the road. Turn left to see the wash-house, then retrace your steps and follow the PR® again.
(7) Come to a road, go to the cross and take the road in front of you (you are now leaving the PR®). Follow this road to a cross.
(8) At the cross, turn right into Rue du Mont Cœur, pass a factory and turn left (follow the wash-house signs). Turn right down the street to the wash-house. Make a U-turn at the wash-house, then turn right again and return to the cross.
(8) Back at the cross, turn right and follow the road.
(9) At the fountain, turn left and pick up the GR®7-76. Go up the road, past a wash-house, and continue on the road as it bends to the left (in the bend you leave the GR®°).
(10) At the end of the road on the right is the discovery trail (signposted). Climb this path, which begins with a flight of steps, and follow it to the summit of Mont Avril. The summit features an viewpoint indicator and a cross with a magnificent 360° panorama.
At the summit, opposite a bench and the viewpoint indicator, take the path that descends due east and joins the GR®. Follow the white and red markings through the forest, pass through the fence and continue downhill. Turn right at the second track and return to the car park.
