The Yzeron valley from Saint-Laurent-de-Vaux

A long walk through the forest and across fields on either side of the Yzeron valley. Quite a few small climbs and descents, some of which are a little steep (at least one climb is too difficult for mountain bikers)

Description of the walk

Park at the top of the hamlet of La Mitonnière in Saint-Laurent-de-Vaux.

(S/E) Start with a fairly steep climb up Chemin de Château Vieux (first tarmac, then dirt road) until you reach the first fork in the forest.

(1) At the crossroads, head towards Le Giraud and follow the almost flat path through the forest to reach this hamlet.

(2) Continue downhill and to the left towards Yzeron on the tarmac road, until you reach a fork with a path near a house.

(3) Turn right onto this path which descends towards the river. Cross it (photo), continue straight ahead on the path which climbs up to the hamlet of Les Roches, then La Brally.

(4) Cross the D489 and take the small path that climbs quite steeply (photo). At a four-way crossroads, join the Aqueduc de l'Yzeron path. During this climb, there are other small paths that also climb, more or less parallel. In any case, when you reach a fairly wide and almost flat path, you are on the Aqueduc path.

(5) Take this path to the right, cross the small stream and you will come to another five-way crossroads (Crêt de Piraluron).

(6) Be careful here to take the middle path. A few metres further on, you will see a sign for Les Arnauds. Walk down a slight slope, then take a short climb to reach Les Arnauds.

(7) Continue towards Samazange by turning left and following the Ruisseau de la Milonière stream to enter Samazange

(8) Take the path down towards the ponds (photo), walk along the lower pond and you will come to a barrier at the end of it.

(9) Go through it, then follow the path on the left down to the river, cross the small footbridge, then go back up the road and turn left until you reach another bridge.

(10) Don't miss the path on the right that goes up towards Saint-Laurent-de-Vaux. At the church, turn right immediately and continue uphill until you reach the car park of the hamlet of La Mitonnière (S/E).

Practical information

The Yzeron river can be crossed at points suitable for pedestrians. The river is very pleasant in summer for cooling off.

A very beautiful hike with a large shaded section and no major difficulties
The section after the pond would benefit from a little more signage

First of all, regarding points 8 and 9, as already mentioned in point 8, I continued along the road for about 320 metres until I reached the crossroads, where I took the path on the left, and it was really perfect.

A beautiful route, what a pleasure to walk in the woods in the slightly sunny weather today.
A nice climb from km 4 for about 600 metres, after which it was pure bliss.
Superb view of the sunlit Alps.
A few short sections of road (fortunately with no traffic)

The route is sometimes poorly marked, especially at marker 8, where you really have to search for the path.
A few steep climbs

A beautiful, fairly short hike (2 hours and 15 minutes for us) with a few challenging climbs.
We particularly enjoyed the sound of the numerous streams on this sunny December Sunday and the mainly rural route.
Contrary to the warning, at point 9 a (large) tree has fallen across the fence, restoring the path after the pond without the need for a detour.

I was able to pass between 8 and 9 as indicated in the route map today. The passage was a bit tricky but passable, as the fence was no longer there or had been stretched out at ground level.
A beautiful route, completed in 2½ hours, but the steep climbs are tough on the legs

As indicated in comment 69, the section between 8 and 9 is no longer accessible.
We think the suggestion to continue along the road and then the path is a good solution.

The instructions are clear but could be more precise at certain multiple-choice intersections.
Please note that the section between points 8 and 9 is no longer accessible, as the barrier at point 9 has been replaced by a fence.
It seems better to continue on the road at Samazange and then, after the hamlet, take a path on the left which appears to be signposted (according to Open Street Map).
Apart from this point, the walk is very pleasant, alternating between pretty forest paths and clear trails that even offer views of Lyon in places.
There are a few slightly steep sections (especially after La Brally), but nothing too challenging over the course of the route.

A beautiful hike, which we did in July 2020 in glorious sunshine. We enjoyed the many sections through the woods. There were two steep climbs and a few tricky sections. Good footwear is essential. Some stunning views.

We loved it
