Features: Forest – river – history – panorama view
Overview: I will say it is a medium to difficult walk, mainly because of the crossing of the scree
Time: around 3-4 hours Km: 10 Hight to climb: 568
You will find the map at the bottom of this page.
This walk brings you to the heart of the Semine valley, and you will be able to explore its hydraulic heritage.
The staring point is in the centre of Saint Germain-de-Joux where it should be relatively easy to find a parking spot for your car. I found ample parking right next to the church.
To find the start of the walking path you’ll have to walk 50 meters down in the direction of Bellegarde on rue de la Gare.
You will soon see the familiar yellow signpost which is right after the petanque area on your left-hand side. The path will take you down to the Giant kettles – but before going there, you should take some time to explore the old sawmill.


The water wheel, which has been completely restored, measures 7,54 meters in diameter and has 96 blades. This makes this water wheel the biggest in the department de l’Ain.
Back in the good old days this little village had no fewer than eight sawmills along the two rivers that connects here, and the last one closed as late as 1998.
One of these sawmills also used to cut stone coming from a neighbouring quarry, and most of the churches in the area were then build with these stones coming from Saint Germain-de-Joux.

When crossing over the bridge you will see a new yellow sign indicating the hiking path. Follow the path down along the river to Les Arcis.
From Les Arcis, follow the signs towards Combe Michel and Marnod,
until you reach this signpost:

The first time I tried to walk this route I was not able to find the path. I admit I was very badly equipped, with no good map, but to my excuse there was also a lot of forest work going on which has changed the original pathway. The trick is to not be tempted to walk down, to walk no longer than 100 meters in a straight line from the sign and keep your eyes to the left. Then, in between the trees, you will see a small path. When you’ve found it, it will take you up into the forest of Beloz.
After some minutes you will reach Pierrier du Rocher de Beloz. This is a mass of loose stones that cover the slope of the mountain. Such masses are also called screes.
Crossing this scree can be daunting. My friend who came along with me was very quick and focused on a rapid crossing, and we were both happy to put our feet back on an earthy path after the approximately 50 meters walking on loose gravel. The forest itself is amazing, with threes overgrown with moss. Bring a camera because with the right light you can take amazing photos here. You will also get a really good view of the motorway and viaducts and witness how it is sculpted into the landscape. I have so many times seen the nature from a car window along the highway. Looking at the highway from another viewpoint enables you to admire the great engineering knowledge that’s made this highway possible.

Moving on along the path takes you up and over to Combe Michel, before you start to descend back to Saint Germain-de-Joux past the small hamlet of houses in Marnod.
In Petit Marnod, we started to wonder if we’d lost track of the path, since we were faced with a barrier across the road. The trick is to walk past it and continue until you see a wall of three logs. The path follows these logs to the left. You will soon be rewarded with another great viewpoint of Saint Germain-de-Joux, the highway, and some small summits.

The Marnod is a really charming hamlet of houses and you will be walking along the road that connected these houses to St. Germain-de-Joux. If you are lucky and find some of the locals out and about enjoying their coffee or a glass of wine, they’ll be happy to talk with you. They also have a really great sense of humour and could end up asking you to watch out for crocodiles and toy cars!
Follow the signs down to Longefand and then back to Saint Germain-de-Joux.
Happy walking, and feel free to share!
