Description of the walk

Park in the car park in the centre of the village of Lhuis.

(S/E) Leaving the car park, turn left onto Rue de l'École towards the retirement home. Walk past it and continue towards Saint-Martin.

(1) You will come to a fork in the road: both streets lead there, but take the one on the right. In Saint-Martin, the pottery is signposted, so head there.

(2) Leave a path leading up to "la Chèvre" on your left, pass the pottery on your right and turn left onto a good path that runs alongside and then crosses the stream coming down from Creux du Nant. This path is marked in yellow. Leave a water catchment on your right and rejoin the path that climbs up from Ansolin.
Turn left. After 150 metres, leave the path that turns sharply to the left and continue straight ahead along the mountainside, ignoring two paths on the right. At an altitude of 650 metres, the path turns sharply to the left and a little further on describes a large curve to the right, finally joining a carriage road at an altitude of 733 metres (sign).

(3) This is where the Montagne de Tentanet loop begins. Take the road on the right and ignore all the paths on the left and right to descend to a fork at an elevation of 570 metres.

(4) Turn left and walk along the small Lac de Crotel, which is not visible from the path. Continue downhill, then start climbing slightly for 500 metres.

(5) Take a path that branches off to the left with a short but steep climb and joins theGR®59. Admire the view of Conzieu before turning left and climbing theGR®59, which is clearly marked and well signposted.
Along the way, there are some lovely views of the Conzieu Lakes first, then Lake Crotel. Watch out for some slippery rocks in the grassy section! The climb continues to the sign and marker indicating the arrival at the summit of Montagne de Tentanet.

(6) A short descent through the rocks leads to a track that is still marked in white and red. Continue along this track for 500 m until you reach a fork (sign).

(7) Leave theGR® and take the path that branches off to the left, which is poorly marked in yellow. 100 m further on, keep to the left and ignore another path that branches off sharply to the right. Follow the natural path, which describes a large arc and leads to a meadow.

(8) At this point, the path is not obvious: keep to the edge of the forest on the right for about 200 m and you will come to a path that branches off to the left. Shortly afterwards, you will rejoin the yellow markings.
Continue to the right down a steep descent on this path which, after a few bends, leads back to the carriage road at an elevation of 733 metres.

(3) Walk 50 m to the left and rejoin the path you took on the way up. Simply walk back down this path to reach the Saint-Martin pottery and then the starting point. (S/E).

A lovely walk, mostly in the shade, with few views (but they were well worth it).
Take care in wet weather between stages 5 and 6; make sure you wear good shoes and carry walking poles as it is very slippery (as indicated on the GR59 signs). In dry weather, it’s quite a steep climb.
The hike took 4½ hours, not including the sandwich break.

A lovely walk, very pleasant, with beautiful views. We parked in the car park by the cemetery at the top of the village – it’s spacious and quiet, so we didn’t disturb the locals. Conzieu is a very pretty little village.

Discover the Tentanet Massif with these views of the Rhône and Bugey.
A challenging route with the ideal elevation gain for experienced hikers. Steep and slippery paths in wet weather.
I adapted the route by continuing along the GR 59 to descend to Lhuis via the Pré de Lhuis a little further north. (On the LEFT, near the RN 883, there is a sign indicating the location).

Hike completed on Sunday, 4 August 2024, with few people around: we encountered four cyclists and three lone hikers.

Reliable description and GPS track. On the climb up Tentanet, after the pylon, the path is narrow and begins to close in: lots of brambles and scratches at the beginning of August... The summit of Tentanet is in the woods, but 2 viewpoints are marked on the map nearby (short detour).

As mentioned in a previous comment, from point 7, I preferred to continue along the GR, then follow the direction of Lhuis via the yellow marked route, which allows you to make a loop and avoid taking the same path on the way there and back. This descent to Lhuis takes a very pretty path through the woods with a viewpoint over the Rhône valley.

The circuit is mostly in the shade, which is welcome in very hot weather, but there are few clear views, which is something to bear in mind before setting off.

In previous years, some hikers have described sections of the GR59 as poorly maintained and overgrown with brambles and nettles. On this beautiful day of 2 April 2024, the entire route is perfectly clear, with well-marked, clean and easy-to-follow trails.
The entire route is in the undergrowth, and this hike must be pleasant in summer when you are looking for shade from the trees.
The highlight is the section along the GR, with a beautiful panorama when you reach the pylon. Then, at the start of the climb along a beautiful trail, short cross paths offer interesting views of the Rhône plain and the Alps.
A few steep and somewhat challenging sections on this GR trail, which can be slippery in wet weather, require a little caution.
For the descent, from point 7, I preferred to continue along the GR, then follow the yellow marked route towards Lhuis, which allows you to make a loop and avoid taking the same path on the way there and back.
A pleasant walk, without meeting anyone, completed in less than 4 hours.

I admit I hesitated a little before choosing this loop as a prelude to New Year's Eve, but it turned out to be an excellent surprise because the climb on the GR59 is steep, let's be honest, but there are no brambles. Despite the rain that preceded it, the trails are not muddy at all, and the ridge section at the end is very interesting, especially in winter, as the vegetation is bare and offers a superb view all the way to Mont Blanc. Best done in good weather to take in the full view. I will do it again on a mountain bike in the other direction to enjoy the rolling climb. Have a great hike!

Hike completed on 24/10/2021. There were two of us, and we found this hike very interesting, with a few caveats: the first climb (300 m elevation gain) sets the tone: a continuous climb but in pleasant surroundings and on a pleasant path. However, the last climb, which is very steep with some frankly steep sections on the GR 59, takes place in a frankly unpleasant environment: you can't see anything and you're walking through brambles, etc. Finally, contrary to what has been described in other reviews, we found the descent bucolic, even when doing all the points (7 and 8 then back to point 3). The hike took 4 hours and 15 minutes, including a break of about 15 minutes at the summit.

This loop is a change from the more well-known Chèvre trail. However, you must wear trousers, as the GR59 is no longer maintained and the first 2 km at the bottom of the GR are difficult to walk on.
Possible alternative: at the point (6), go straight ahead rather than keeping to the GR on the right. The trail passes by the best viewpoint of the hike, which can also be used as a picnic spot. The trail then quickly rejoins the author's route.
Note: the loop can easily be completed in less than 5½ hours.

The route is indeed well shaded, but it's still a beautiful walk. The GR-59 is overgrown in places, but the route remains visible. The climb is challenging and there aren't many views, but the scenery is nice.
However, we personally added a small variation that extends the route by about one kilometre.
before point 7, follow the GR along a forest path and descend to LHUIS, arriving in the vineyards just north of the village..
A beautiful walk, admittedly without much in the way of views, but a nice 16 km training hike with a nice elevation gain.

The route is well shaded, but the GR59 is a bit neglected in places. Brambles and nettles have taken over the path, which is a shame.
There are no yellow markings on the descent, but otherwise there are beautiful views of Mont Blanc and the Bugey plain.

A beautiful route offering views of the Conzieu lakes, the Innimont plateau and the Rhône plain. The climb is challenging, but the path is well marked and there are no risks. To finish and avoid the road, return via the top of LHUIS and discover the arboretum that has been planted above LHUIS.

Hello,
I have just returned from this hike. The description is accurate and the map is precise. I also had an altimeter (which must be set at the start in Lhuis at an altitude of 394 m), which is more than sufficient.
The description no longer matches the terrain on the descent: the explanations are vague (points 7 and 8) and led me down the wrong path; whereas (this must be new since 2014), all you need to do for the entire descent (from point 7) is follow the clearly visible yellow markings.
One disappointment: the almost complete absence of views along the route, which is entirely in the forest. The opportunities are well marked in the description: don't miss them!
In summary, a lovely walk to stretch your legs at the end of winter in a mountain range where the snow melts very quickly
