From Saint-Paul d'Izeaux to the village of Plan

A very varied walk. In the first part, you walk alongside magnificent ponds covered with water lilies. The return via Camp de César offers magnificent views of the Bièvre plain and the surrounding mountains.

Description of the walk

Departure from the centre of the charming village of Saint-Paul-d'Izeaux.

(S/E) Turn your back on the church and head straight ahead (signposted "Le Joland"), due west. At the two forks, take the right-hand branch. The road curves to the left, then makes a sharp right turn. You will arrive at a hamlet.

(1) At the hamlet of Les Franchises, follow the small road on the left. A little further on, ignore the path that branches off to the left. Very soon after, you will come to a fork: take the left fork. 500 metres further on, turn right onto a small tarmac road.

(2) Take the road on the left and follow it for one kilometre through a small wood. When you come to a poplar plantation on the right, take the path that branches off at a 45° angle to the right (yellow markings). Be careful, as you will soon have to leave this path and turn right again (it is easy to miss the path as it descends steeply).

(3) Cross the D504b to take the small road that climbs opposite (Chemin du Polonfrey). Leave it very quickly to take a path on the right that is not entirely marked on IGN maps. After a while, ignore a path on the right and you will soon come to a small road, which you take straight ahead.

(4) Turn onto the first road on the left. Follow it, passing three magnificent ponds covered with water lilies. After the third pond, the road turns left. Ignore the first path on the left. When you see a walnut grove on the left, pay close attention.

(5) After the walnut grove and a forest, take the path that branches off to the left. After a while, ignore a path that comes in from the right at a 45° angle and take the next one. It is not very well maintained. At one point, it is even slightly hidden by a hazelnut tree (if it is hazelnut season, take advantage of it...). When you reach a T-junction, turn right. You will come to a small road, turn right, then very quickly left at a 45° angle. You will enter the village of Plan. Walk past the church.

(6) In the centre of the village, at the crossroads, go straight ahead (signposted "Camp de César"). It is marked in yellow all the way to Camp de César. Ignore the small road on the left (the "Camp de César" sign is for vehicles) and continue straight ahead. Ignore a path on the right. The road climbs steeply (170 m elevation gain in 1.3 km). You will come to a small road; follow it to the right until you reach Camp de César.

(7) At Camp de César, enjoy the view. Take the path on the left as you arrive (north-east). Signposted towards Saint-Paul-d'Izeaux. Follow the path, which very quickly descends steeply. At a fork, take the right-hand path (yellow markings). You will come to a small road.

(8) At a place called Girin, turn right (towards "la Tulière"). When you reach a crossroads, go up to the left (again towards "la Tulière"). Follow this small road to the hamlet mentioned above.

(9) When you reach the centre of the hamlet, turn left (signposted "Saint-Paul d'Izeaux 1.3km"). Follow this path down to the village. You will find yourself back at the central square and the car park (S/E).

Notes

Drive to the small village of Saint-Paul-d'Izeaux (between Lyon and Grenoble, at the eastern tip of the Chambarans). Park in the central car park in the village.

At Camp de César, there is a bar serving drinks, crêpes, etc. I passed by four times but never saw it open.

I didn't see any shops in Saint-Paul-d'Izeaux or Plan.

Worth a visit

The charming villages of Saint-Paul-d'Izeaux and Plan, the walnut groves, and the dense vegetation of this part of the Chambarans.

The Étangs de Plan are best seen in early summer when the water lilies are in bloom.

In the second part of the walk, there are a series of beautiful panoramic views over the Bièvre plain, the Pilat mountains, the Vercors, the Chartreuse and the Mont du Chat.

Nice loop!
I think there are too many paved sections for a hike (but fortunately there is very little traffic), but since I ran the circuit, it went by faster...
Some of the paths were not maintained (especially between points 1 and 2) and we had to make our way through tall grass.

Hike completed with GPS tracking in 4 hours, including a picnic. A walk with some beautiful sections (villages, ponds, Caesar's camp, etc.). However, there was too much tarmac for my liking. Mainly frequented by trail runners.

Sorry, Visorando does not plan to create an "Ardéchois" section, nor any other section for specific regional characteristics.

Yes, that's what it's like to live in such a beautiful region and therefore become very particular about the quality of hikes. Have a lovely evening.

Thank you for your comment.
Indeed, Visorando will need to add a special section for the Ardèche region.
Enjoy your walks.

For residents of the Ardèche region, this route is of no interest, both in terms of the scenery and the long stretches of road and lack of shade.

I did this hike a second time and it was just as good. We stopped for a snack in the village of Le Plan in front of the church before the big climb to César's camp. The bistro was closed, so we couldn't have a drink (because César had gone off to conquer the south of France!!!!!!!). Anyway, the ponds with the water lilies were as beautiful as ever. No comment on the rest.

A beautiful hike with no apparent difficulty. At the start, after leaving the road, the path is not maintained and the grass is very tall, so watch your step (tick). When you arrive at the ponds, the water lilies are in bloom and very beautiful, but watch out for gunshots very close to the road, which scared us. When we arrived at Camp Sésar, we asked a forest ranger why he was shooting when hunting season was closed. He said it was to chase away the crows that were eating the corn. (The bar at Camp Sésar is closed).

damn, visorando! I had to rewrite everything because of a banned word (which I wasn't notified about) and now I'm back to square one...

So, from memory:

no particular problems with the description, except at (5), when turning right to go up to Plan.

The description says to ignore a path that comes in from the right at a 45° angle, but there are three paths in a row. The first comes from a meadow, the second is in the forest (and immediately makes a left turn before going uphill) and the third is the most similar to the description (because it is in very poor condition). But after 20 metres, there is nothing but brambles, tangled branches (fall) and no more path.
We continued on the main track; after about 500 metres, there was a post with small yellow signs; one of them, on the right-hand side, indicated "Plan 0.6 km". According to the map, it joins the second path mentioned above. We did not take it because it was a steep, muddy climb due to the passage of machinery.
We turned around and ended up taking the second path, the one in the forest. It was in very good condition, with no hazel trees. We think that this path has been rebuilt since the route was established.

Very pretty passage near the ponds, which were still frozen yesterday. Private ponds. No tables along the route for a snack break. A tree trunk by the side of the road above the ponds did the trick.

Nothing of note in Plan, except for a manor house on the right as you start climbing towards César's camp. Information plaque outside

The bistro/restaurant at César's camp was closed (only open by reservation, as indicated on the door). Tried it in 2011, when the speciality was frog legs + gratin dauphinois. Excellent.
I don't think this small white building with brown shutters spoils the landscape either.

The descent to Girin is indeed partly stony and quite tricky. If I do the route again, I will try to go via "Le Jolland" at César's camp, which will avoid both the stony descent to the hamlet of Girin, its tarmac climb up to La Tulière and its numerous dogs, which have nothing better to do than bark at you before, during and after your passage.
This may seem insignificant to some, but it bothers me because it breaks the peaceful and soothing atmosphere of such a hike. We had already endured two remarkable specimens in Plan, from our arrival in the village to just below César's camp (which is quite a trek) and without interruption.

In conclusion: a nice walk, a bit physical (steep slopes), a pretty passage to the ponds, beautiful views of the Bièvre valley and then a very beautiful panoramic view at César's camp, despite the clouds.
Few people yesterday (no hikers, one brave cyclist, three motocross bikes - long live electric! - and a few cars.
There was only one tree trunk across the path, after Polonfrey, but it was easy to get under.

Thanks to the author.

Hike completed in just under 4 hours.
The second part of the descent to Girin is quite "unpleasant" because there are lots of stones rolling underfoot: 500 metres with gradients of 22 to 28%.
Two interesting climbs
- the climb to Plan: 400m between 23 and 26%
- the climb to Camp de César: 1.4km between 20 and 34%.
Beautiful views at Camp de César over the Bièvre plain, the Chambarans and the Vercors and its foothills.
We didn't think that the bistro at the highest point of the route detracted from the landscape that much...
A short walk enjoyed by the whole group

A pleasant hike with beautiful scenery and panoramic views despite overcast skies.
Some of the slopes are a little steep, including those leading up to César's camp.
We didn't meet anyone and saw very few vehicles.
Overall, a very positive experience.

A lovely walk in this spring-like February, ideal for kicking off the year's hikes and getting into shape (note that the climb to Camp Cesar is a bit of a workout...). Very few vehicles and only one jogger encountered – in short, perfect communion with peaceful and soothing nature. Thank you for this lovely route.

A pleasant route for one of the first days of spring while waiting for the mid-mountain hikes. You walk a little too often on tarmac roads, but as there is very little traffic, you have time to enjoy the landscape, the small woods, the ponds, etc. With the necessary attention when reading the description, you can do the circular route without any problems, as reading the map confirms the text.
Thank you.

hello, today, 2 April, we went on this hike and enjoyed beautiful views of the Chartreuse and Vercors mountains and even the peaks of the Ardèche, which are still covered in snow at the start of spring.
We had a coffee at the Camp de César bar and restaurant, which opened last Saturday. The owners are very friendly
and the restaurant does not interfere with enjoying the scenery.
Coffee is €1, with complimentary biscuits.
Good signage, no problems.
SEE YOU SOON, JEAN PAUL
