Head to Commelle and park in front of the church, not far from the town hall and the cemetery.
(S) Head south towards the Liers plain. Cross the D51 departmental road. Take Rue du Château to reach the hamlet of Grand Battoir. Cross through it.
Yellow markings.
(1) At the exit of the hamlet, take the dirt track on the left (opposite Chemin de la Rivière) and continue, leaving two paths on your left. When you come to another path (T-junction), turn left to cross the D51.
(2) Cross and continue straight ahead, climbing northwards this time (sign for Villarnoud le Bas). Follow a small tarmac road (Chemin de Pocon) and take the first small road on the right. Pass a dead end on the left, then one on the right. Pass a small road that descends towards the plain on the right.
(3) About 50 metres further on, take the first path on the left towards La Grande Chaume. It appears to lead to private properties, but it continues. Begin the climb up the hillside via a steep little path. You will come out onto a meadow and continue along the side of the field, if there is hay. Continue to follow the yellow markings until you reach a small tarmac road which almost immediately becomes a stony track (signposted "Étang La Grande Chaume"). Pass by the "Petit Étang" on your left (don't miss it, you can only see it from one spot...) to reach the Étang Malymorte on your right (there are four small steps to access it).
No more markings.
(4) At this point, leave the main path and take a more secluded path on the left. Walk along the Étang du Mucillon, which you can see on your right. After the pond, pass two forest paths on your left and reach a clearly marked fork.
(5) Ignore the left fork, which leads to the Étang de l'Émina, and take the right fork. Go around the Étang de l'Émina (you will see it towards the end, on your left between the trees).
(6). Take the only path on the right that descends steeply into the valley. Once at the bottom, cross a small stream that is sometimes dry (signposted "Forêt communale de Chatonnay") and further on, ignore the path that branches off to the right and climb up to the left towards the wreck of a Renault 4 (how did it get here?). Once you have climbed the steep slope, descend again.
From now on, it's mostly downhill. Follow the valley, ignoring the paths that branch off to the right and left. At first, follow the left bank of the stream, then very quickly, and for a long time, the right bank. After a long pond hidden behind a hedge, you will come to a fork.
(7) Take the left fork. At the end of the path, you will come to a small road. Continue straight ahead, heading south. Finally, turn left onto thesecond small road (Chemin de l'Église) to return to the starting point.
