Description of the walk

(S/E) Leave the car park and head up towards the D41 road that connects Saint-Jean to La Côte. Take the road down to the right (east). Cross the road and take the first street on the left (signposted Chemin du Nemoz), which climbs up towards the hillside. The tarmac gives way to a gravel path. Follow this wide path, ignoring any paths branching off to the right or left (even the one on the left, which is closed to all vehicles and where mushroom picking is prohibited by municipal decree...). When the slope levels out, you will come to another path of the same size. Turn left.

(1) You will soon arrive at Étang Commelas, which is on your right. It is open to the public. Continue along the path. You are now on a plateau, and the path is relatively straight. Ignore any paths branching off to the right or left. The path then descends to the D518 road.

(2) Cross the road. Be careful, as traffic travels fast and you are on a bend. Take the small tarmac road on your right (sign: Route de Semons). Further on, ignore a road that comes in at a 45° angle on your left. At the next crossroads (sign: La Croix), turn left. Go down to a T-junction. Turn left.

(3) On your left, you will see Étang Cadenas, which is relatively hidden by vegetation and very enclosed. Drive past the pond.

(4) You will come out onto the D41, which you take on the left. Take the first path that goes uphill, also on the left (ignore the yellow cross that tries to dissuade you). When the path stops climbing, you will see several private ponds on your right. You will come out onto a small road (the tarmac ends when you reach it...). Take it on the right. You will come to an accessible pond.

(5) At the end of the pond, turn left at the sign: "Étang Gonnet - 530m". Follow the direction of Semons, opposite you, slightly to the left. The path climbs up to a meadow. Go around this meadow.

(6) At the end of the meadow, you will come to a T-junction, where you turn right. When you return to civilisation, at the first fork, take the small road that goes down to the left (despite the yellow cross). At the next T-junction, turn left again. At the "Stop" sign, you will, of course, turn left again to return to your starting point at the Semons car park (S/E).

You will find shops and basic services either in La Côte-Saint-André or in Saint-Jean-de-Bournay.

Worth a visit

You will pass several ponds.
The Semons forest is very welcoming (please note that mushroom picking is regulated by a municipal by-law).
At the end of the walk, if the weather is clear, you will have a beautiful view of the Vercors peaks.

A walk that must be beautiful in fine weather but which has its charm in this season because there is calm everywhere and it is restful by the ponds.
There are numerous woodcuts and a large area of young plantations. The vegetation is still dormant, but there is plenty of holly and broom.
At the end of the walk, there is a slight glimpse of the Vercors peaks.
Magnificent!!! The walls of the church, the town hall/school and some of the houses are made of pebbles laid in a herringbone pattern.
Thank you to the author for this route, which I really enjoyed.

A pleasant, easy walk. A bit overcast today, so not much of a view. But the forest trail is nice. Not too muddy.

Hello,
I went over the walk again. There was indeed some ambiguity.
I think the new version of the description is clearer.
Happy walking.

Sorry,
As soon as possible, I will repeat the walk, at least the beginning, to try to see where there is a risk of ambiguity.
No hard feelings, I hope.

For the first time since I started following Visorando routes, I was unable to complete this hike. I took the Nemoz path, but then I couldn't find the fork indicated. I should mention that I don't have a GPS. Please indicate the distance from the Nemoz path.
Nevertheless, I would like to thank Yannick Josset for his accuracy, as I have enjoyed many of the walks he has suggested.

A peaceful walk, mostly through the woods and along a few small roads! Varied woodland: conifers, but also chestnut trees, birches... For those with a sweet tooth at the end of summer, there are blackberries along the way. Ponds, views of the countryside in this corner of the Dauphiné region. And at the end, even a "panoramic" view! Very nice...
