Ri d'Olon loop

A pleasant walk along the Ri d'Olon stream and then through walnut plantations. The first part of the route is through the woods and the second part is in the shade of walnut trees. This walk is suitable for young children and even pushchairs.

Description of the walk

Access: Coming from Rives, turn right and head down towards Moirans Manguely. Coming from Voiron, Valence or Grenoble, take the Moirans hillside road. Park along the D12C at the only building on this section of road.

(S/E) The path descends along the road from a small building and quickly reaches the edge of the stream. Once you reach the stream, the path branches off to the right and runs alongside it. Follow this path through the woods for a good two kilometres, with the stream on your left. Please note that the path sometimes crosses the stream, leaving it on your right for a few dozen metres. Join the Route du Sabot at the entrance to Vourey.

(1) Continue straight ahead on this road, leaving Route du Point du Jour on your left. Continue along the stream, walking on the wide path. After a few bends, the road ends at a Y-junction.

(2) Turn right onto Route du Moulin. After two large bends, left then right, and about 800 metres further on, you will come to a four-way crossroads.

(3) Turn right onto Route de Cerveloup. Continue straight ahead, passing access roads to houses on your left and then on your right.

(4) At the fork (Couvoir de Cerveloup), continue left on Route de Cerveloup, which climbs slightly. After a right-hand bend, you will see walnut trees. Continue for 200 metres. At a fork, take a path on the left that is just wide enough for a car (Chemin des Acacias). Do not be distracted by the small paths that branch off to the right or left and continue straight ahead on the wide path. Shortly before a farm and some houses, the path gives way to tarmac.

(5) At the crossroads, continue straight ahead and take thefirst right, the D12C. Further down, you will return to the starting point (S/E).

Notes

No specific markings.
The path through the woods may be less passable after heavy rain (mud puddles).
This walk is also part of a mountain bike circuit.

Worth a visit

The only point of interest is a sawmill with its machines powered by the stream, the first building along the stream at the entrance to Vourey.

A pretty route that starts along the Ri, continues through Vourey and continues through walnut groves with views of the Chartreuse peaks.
An easy and varied trail.

The second part is a bit difficult because it's a little steep in places, and on tarmac.
Not suitable for everyone
However, the entire length of the Ri d'Olon is magnificent, green and shaded, quiet and peaceful, etc
For my elderly clients, I do the round trip along the Ri d'Olon and it's very good
Thank you

Great hike; the first part along the river is superb, followed by a bit of road but along walnut trees, which is also nice. We do it fairly regularly.

Inaccuracy in the description: "follow this path through the woods for a good two kilometres, with the stream on your left".
In reality, at the first small bridge, you have to cross the stream, which is then on your right for about a kilometre, then cross it again, so that it is on your left again, just before you reach the old sawmill and join the Sabot road.
If you continue without crossing the first bridge, the path continues for a while and then ends.
There is heavy traffic on the section along the Ri d'Olon, which is very pleasant.

Be careful when walking along the river. It is recommended to keep the river on your left, but when you reach a bridge, you must change sides and not stay on the right side of the river, as it is a dead end. Cross again further on over a bridge to return to the left side of the river...

CAUTION: numerous trees have fallen across the path, which runs through private land. Signs prohibit access to the path for this very reason. Not very inviting.
This hike should be avoided if possible, especially on windy days (high risk of further tree falls).

Easy hike
Along the stream at the start in the woods, making it suitable for a summer outing.
Upon arrival in the village of Vourey, the hike follows a busy road, which is very disappointing as the road is dangerous.
The hike then continues along a dirt track where you are supposed to have a view, but the trees limit the view considerably.
Finally, the return journey is along a tarmac road, which is dangerous.
Conclusion: an easy hike but disappointing compared to the views promised in the comments.

I chose it because of a problem with my knee, modifying it so as not to go through the low, damp area near the stream, but taking a small parallel road higher up on the "plateau" while maintaining the length and loop of the circuit.So it's an almost flat circuit with beautiful parish-specific views of Chartreuse and Vercors, a real treat, these hillsides of Moirans, continuing along the same route either towards Voiron via Le Criel or towards Tullins via the hillsides of Vourey. Very easy, even with children.

A very pleasant loop with beautiful views of the Vercors. However, be aware of a small inaccuracy in the route, already mentioned in other reviews.

A slight hesitation about one spot: you do have to cross the river via a bridge. From this point onwards, the river is on your right. Otherwise, it's a very pleasant path at the start, with the river running through the woods.

As one hiker mentioned, contrary to what we are told, we should never cross, but yes, at point 1, we have to cross the small bridge and then we have the river on our right, but this is only a minor detail because this short, well-shaded hike is very nice. I think it needs to be corrected because it causes hesitation. We came across many families and dogs, as well as a pram
