Large car park below Lac du Ronzey (an anagram of Yzeron).
(S/E) Climb up onto the dam and cross it. Turn right and follow the lake, then the picnic area.
(1) Pass the lake enclosure and take the path that climbs up to the left towards the forest. Stay on this path, which winds between deciduous trees on the right and conifers on the left. Ignore the paths that climb up to your left.
(2) At the pumping station, continue straight ahead, ignoring the marked path that branches off to the right. After a bend, the path, which is shaded and very pleasant, runs along the edge of the forest. Turn right at the first intersection.
(3) You will find yourself on theGR®7. Turn left at the first intersection, after about 250 metres.
(4) Take the path that descends to the right and continue straight ahead.
(5) When you reach the road (D489), follow it to the left for 300 metres. Take the path that branches off to the left and runs alongside the departmental road.
(6) When your path reaches the crossroads with the departmental road, take the narrow path, which is sometimes hidden by grass, that descends directly to your left. After 100 metres, you will arrive at a small road which you follow straight ahead until you reach the hamlet of Jayoud. After the farm, at the crossroads, take the path on the right. At the edge of the forest, it will lead you to a small road which you take to the right for about 200 metres.
(7) Take the road that descends to the left. After the Pocachardière farm, the road turns into a dirt track and descends towards the stream. After crossing it, continue straight ahead until you reach a paved road, ignoring the marked path that branches off to the right. On the road, climb to the left, then turn left towards the Ruillardière farm.
(8) Just before the farm, a path branches off to the right and passes behind it. Take this path. The path climbs gently through a beautiful pine forest.
(9) The path bends to the right. When we passed through, a tree was blocking the way at this exact spot. Go around it on the right, which will bring you back to the path. The path passes along market gardens and leads you to theGR®7, which you take to the left.
The wide path passes through woods and a large, recently cleared area.
(10) When you reach an intersection with several paths, continue straight ahead, ignoring the marked paths that branch off to the left and right. Your path descends down the slope. Continue straight ahead towards the village of Yzeron.
(11) When you see the lake, take the path that turns left towards it (or cut across the meadow). Cross the dam again and you are back at the car park (S/E).
