A lovely walk, but quite sunny... I think it’s best to start from Romanèche; otherwise, the final hour’s walk to Cize, on a gentle incline in the sun, was quite a struggle for me. Starting there, however, gives you a chance to warm up and see Cize Church before the short climb. For a picnic, either at the various viewpoints or at the start of the descent through the rocks, which offers a superb view. Next, don’t miss the viaduct, as well as the copper works – steeped in history, entertaining and, on a human level, a wonderful story.

We started from "Cize". There's no point in starting from Grand-Corent. Beautiful views of the ridges. The route is slightly technical in places. Best done in dry weather as the rocks are very slippery. From the viewpoint, take the forest path rather than the road to reach "Romanéche"
The return trip from Romanéche is a bit tedious and not very interesting, but it's part of the loop
Take the time to visit the Cize Boloron viaduct, which is very impressive and spectacular

A very pleasant loop with no major difficulties except perhaps the climb up the large scree slope, where you will get your heart rate up a little. Otherwise, there are beautiful views of the Rock

Beautiful views of the Ain River with the cliff-side passages of the Jarbonnet rocks.
After the viewpoint, we continued on to see the dinosaur footprints at Villette.
The climb back up to Grand-Corent doesn't offer much apart from the elevation gain and distance
It would be better to start and finish in Cize.
There is no good viewpoint of the Cize Bolozon viaduct.

An easy and varied hike, we set off in the mist and the sky cleared as we walked along the trail. The autumn colours gave the landscape a mysterious atmosphere.
Definitely worth repeating!

Following Koalak's suggestion (12/08/24), we started the hike in Cize, at the church car park. And as suggested by Hervé49 (29/07/24), we didn't take the road between the viewpoint car park and Romanèche. We easily found the path/trail at point 7, which took us to the church in Romanèche.
Note that there is a small accessible arch between points 6 and 7, coordinates N46.19018, E5.45851 (approximately)
A beautiful hike.
However, you will need hiking boots, or even walking sticks, and avoid taking children under the age of 7. The terrain on the ridge, often sharp limestone pavement, is difficult, and you often walk along the cliff edge.
Thanks for the route.

Nice hike, especially the part with the view of the Ain River, which is magnificent.

This is a pleasant hike if you want to visit villages, but personally, I don't see the point of starting in Grand-Corent, except to add more walking time, as it means driving up and then walking back down (and vice versa on the return trip). It's better to start directly in Cize!

However, the trail is very quiet, which is a plus for peace and quiet, and the view from the top is very pleasant. It's not particularly difficult, which is good for those new to hiking.

Beautiful hike with stunning views of the Ain River.
Don't hesitate to follow the edge of the cliffs, which are not very dangerous and offer the best views.
The viewpoint is of little interest except for the picnic tables.
However, why go back down the road to Romanèche when there is a shaded path in the forest that runs parallel to the road and takes you there?
Just ignore the yellow and red cross just before you reach the viewpoint and follow the yellow-marked path that leads to the church.

A great hike that we were able to follow for the most part thanks to the red and yellow markings, only as far as the viewpoint (point 7) because after that you can't get back to the car. It's still worth continuing a little further along the yellow and red markings after the viewpoint for some beautiful views, then retracing your steps to find point 8.

Be careful between points 3 and 4, though, as there is a gate blocking the road at the hairpin bend. We would have liked to go through it, but there was a herd of cows with horns standing there. When we reached the gate, we turned back and took a small path that leads into the forest on the right. The path is fairly well defined, then continues over stones. It climbs a little, and once the stones are over, we took the path on the left to return to the Tour du Remontant and thus bypass the cows, arriving at point 5.

A beautiful hike with no difficulty. The main attraction is the magnificent view of the river from the Rochers de Jarbonnet.
The only downside: the box tree moth caterpillars falling from the trees, which are unfortunately still very much present...

The path leading out of the cliffs is not very visible... no signs...
