The Conzieu lake tour

Hike around the Conzieu Lakes, visible from the heights, and Lac de Crotel, which cannot be seen. The hike takes place on good paths and a few steep trails. Spring or autumn in dry weather is preferable, as the few difficult passages can become slippery.

Description of the walk

Park in the car park at Conzieu cemetery.

(S/E) Walk past the cemetery. Take the path down to the village of Conzieu. At the bottom of the path, take the road on the left for 30 metres, then turn right into Rue des Lacs and walk down to the river.

(1) Cross the bridge and take the road on the right. After a hairpin bend, you will come to a fork.

(2) Leave the road on your right, which you will return to later. Follow the road straight ahead, which will become a good path: you are now on theGR®59(red and white markings). Follow theGR® along the Lacs de Conzieu until you reach a road, where you leave it.
Take the road on the right until it ends, 100 m further on.

(3) At the end of the road, take a path on the right, which quickly begins to climb.
The slope becomes quite steep for 300 m.

(4) As you pass, a small gap allows you to see the Conzieu Lakes.
You will reach a pine forest and the path will become almost flat. After 300 m, on a path littered with trees felled by previous storms, you will come to a beautiful carriage road.

(5) Turn right. The path descends for 750 m and arrives at a fork.

(6) Leave a good path that descends to the left towards Saint-Benoît, and also leave a poor path that branches off to the right. Continue straight ahead on the good path that leads to Mont Pela, which you will leave on your right.
After another kilometre, you will reach a fork where the road from Groslée joins.

(7) Take the path on the right that descends for 500 m until you reach another fork.

(8) Take the path on the right and follow the small Lac de Crotel, which is almost invisible through the trees. After 1 km on this path, when it starts to climb slightly, a trail branches off at a 90° angle to the left and climbs very steeply. Take this trail and, after 30 m, join theGR®59.

(9) An electricity pole marks the point where you start to descend back onto the GR®. The path descends through the rocks, where a few steps have been carved out. Be careful, as some sections are slippery.
Follow this path downhill until you reach a good track that takes you back to the bridge in the village of Conzieu and the car park (S/E).

A really lovely route with varied scenery, though the signposting is indeed very poor, so thank you, Visorando!! Especially around point 9 – I’d gone straight on, but luckily the trail was there. The descent is steep and can indeed be dangerous in wet weather!
A bit more monotonous between points 6 and 8, but a lovely view of the River Rhône.
And as I walk a bit faster... I did it in under 3 hours... but I stopped for lunch in the wooded section, which was lovely at this time of year when there’s no one around.

a pleasant, easy walk to get some fresh air, with a view of Lake Conzieu at one point. At one place, the trail is blocked by a cable, probably to prevent motorbikes and quad bikes from passing. I stepped over it (it appears to be private property), even though the GR trail has been there for years

Nice hike, except that the lakes are not very visible . There is a steep climb above the lake, where the vegetation tries to prevent you from passing. Then, at the end, there is a nice descent down a staircase carved into the rock.
Enjoy the hike.
Thanks for the route info

The section in the woods is very pleasant on this hot day.
The section between 6 and 7 is a bit monotonous.

Easy hike
The path between points 6 and 7 is pleasant with unobstructed views
Point 8 is not very clear; you need to pay attention so as not to miss the path that climbs up to the left
please note that if you arrive at the junction signposted "la grange de l'orme", you need to turn back as you have gone too far!
Did not see "le lac du Crotel"
On a positive note, the box trees attacked by the box tree moth are recovering and turning green again...

hello, the route is nice with a slightly steep climb for children, but once you reach the top, there are no more markings, so take the main path on the right. At point 9, you have to guess which paths cross, as there are no signs, so I followed the main path, which ended in a dead end and the other paths lead nowhere, so I had to find another path further down, crossing through brambles (ouch, my arms and hands!). Otherwise, at the top there's a beautiful view of the Rhône and the Alps, as you can see on both sides
a lovely walk.

hike completed in 2015 and repeated on 6 December 2019. Very good route, weather just as we like it (a little sun), but be careful at the arrival point at electricity pole no. 10, where there is a large sign warning of rockfall. We passed through without incident. Good hike

We expected to see more of the lakes. They are only visible at certain points, but the walk is very pleasant with a varied route and beautiful views in good weather.

Easy hike to follow, with directions and a map.
The views of the lake are rather limited, but there is a beautiful viewpoint just before descending at the end of the walk.

Hello,

Thank you for taking the time to give your opinion.

when you arrive at the pine trees, there is no visual indication, and the same applies at the fork with Groslée

As the signage is not the responsibility of the author or Visorando, "Route on map" is not intended to evaluate the signage, but rather to assess whether the route shown on the map corresponds to the actual terrain.

Visorando does not recommend signposting as it can be modified or removed, whereas information about the terrain is stable.

Visorando provides a detailed description (which can be improved) and an IGN map at a scale of 1:25,000. And if signposting is essential for you, Visorando provides virtual signposting: a GPS app.
This tool, offered free of charge by Visorando, allows you to validate waypoints and thus clear up any doubts about the route.

See you soon!

access to the lakes is no longer possible. It is a huge quagmire due to the tractors pulling the wood
furthermore, the path is impassable due to deep ruts filled with water a little after Rubieu, all the way to the bottom of the lakes
when you arrive at the fir trees, there is no visual indication, and the same applies at the fork with Groslée
the same applies to the small path leading to the electricity pole
