Description of the walk

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.

Notes

The description was thoroughly revised on 29 May 2019.

There is a water source at the end of the route, at the entrance to the cemetery (you can quickly go there at the start).

At certain times of year, the forest paths can be very muddy.

Worth a visit

The Liers plain.
Some ponds and the Bois de Commelle woods.
The charming valley of the Ruisseau du Moulin.

I get the feeling that at some point you strayed from the original route... sorry to hear that.

After point 6, you have to cross the stream several times, which is very difficult as the stream was deep and wide in places. It’s not as straightforward as others have noted. In particular, the GPX track is incorrect along the stream as it doesn’t go via the final climb. Making your way through the undergrowth is a bit of a struggle!!!
The start of the hike, from the departure point to point 2, is of no interest.

I’m revising my review because I got the walks mixed up – I did two in the same area over two days. I admit that, up to point 2, it’s not particularly interesting. At point 6, it’s at the bottom of a valley and it’s not easy to find the path, especially as the route isn’t on the right side. As for the streams to cross, I did get my feet quite wet, but I’d expected as much given the rain we’d had. Still, overall I really enjoyed this hike exploring the ponds. Thanks to the author

The route begins along the edge of meadows and fields being prepared for cultivation, continuing uphill with a glimpse of the Alps, through an impressive forest of bare trees of various shapes. Along the edge of the paths, you will discover ponds and pretty streams in a peaceful setting punctuated by birdsong.
There is a beautiful church with pebble walls laid in a herringbone pattern, like many buildings in the Nord-Dauphiné region.
Thank you to the author for this nature walk.

A very pleasant hike that goes from the plain to a wooded area after a good climb and the discovery
several peaceful ponds, a bucolic passage through the valley adorned with beautiful little streams that meander through it.
Thank you to the author.

This gentle stroll through nature is easy going!
Flowers, birdsong, frogs croaking, peace and quiet... in short, everything we love about hiking.
We had a picnic on a bench next to the fishermen's hut on Malymorte Pond: very nice
Thank you for this circular.

A pleasant hike, except for the beginning, where the route across the plain is uninteresting except for adding kilometres. A pity

The hike is pleasant this afternoon. However, the path mentioned in the comments to avoid crossing the main road is not usable as it is private.

Indeed.
And from the satellite view, it appears to be operational. That could be a solution.
Thank you for that suggestion.

Looking at the map, you could perhaps head directly east from the starting point; there is a path marked out that joins the route between points 2 and 3. I didn't take this path, so I don't know if it's pleasant. It would shorten the walk a little, but it would avoid having to cross the main road twice and walk through the fields.
Best regards
