Chancia walks

The village of Chancia, dating back to Roman times, stretches lazily along the lake formed by the junction of the Bienne and Ain rivers and the Coiselet reservoir. Here, everything encourages relaxation. On this route through the hills above Chancia, you will be enchanted by this little corner of paradise.

I suggest a short hike (about 1 hour) from Chancia to the small summit of Molard de Netru (491 m). There are some beautiful views to discover.

From Chancia, I suggest you return to Montcusel via a pretty loop trail: first, you follow the Bienne River at a distance, then you climb a few hills with beautiful views, especially towards Lac de Coiselet.

I suggest a route that is almost a loop, with some beautiful views, to reach the Pic d'Oliferne from Lac de Coiselet (Condes). There are no major difficulties to encounter. At most, there are a few passages that require caution if the ground is slippery (see below).

The aim of the hike is to complete a circular route overlooking the village of Dortan and Lake Coiselet. There are many beautiful viewpoints along the way.

Interesting viewpoint offering views of the Ain valley (Vouglans Dam, the Haut Jura mountain range and Mont Blanc in good weather). The ruins of Oliferne Castle are now of considerable interest following restoration work carried out by volunteers.

Discover Oliferne Castle via the ridge paths. Forget the wide, uninteresting track and enjoy the pleasant paths and panoramic views, where it is practically impossible to go wrong if you follow the yellow markings. Please note: some areas require extra attention when walking with children.

Starting from the workers' village of Dortan, this walk takes you through the Bois de Chatelard forest to the Pierre-qui-Vire and its rocky promontory overlooking Lac de Coiselet. Then, in the intimacy of a rocky cirque at the end of a shady valley, you will discover the waterfall of the Ruisseau de Maissiat, which has been building a pyramid of tufa for thousands of years.

This hike begins with a steep climb, rewarded by numerous panoramic views of Lake Coiselet. It continues along a pleasant ridge with beautiful views and ends with a visit to the ruins of the medieval castle of Oliferne, which offers a 360° view, before descending back to the starting point.

A circular route starting from Martigna and passing by four viewpoints overlooking the lakes of Chanon and Vouglans. From the top of the cliffs, the viewpoints invite us to contemplate the lush greenery and the reflection or sunset on these lakes.

Hike punctuated by beautiful views, following the route of ancient rutted tracks. Passage at the Pierre Énon.

Walk in the forest with a view of Lake Antre and the Jura Mountains

Il est proposé un parcours en boucle un peu sportif, dont la finalité est de rejoindre à partir d'Oyonnax la Prairie d'Echallon, puis de revenir via le Lac Sous les Mousses (et à proximité du lac de Viry) puis le Mont de la Chaux et la Pointe de Biez.

The aim of this hike is to take you to Lac Genin from the centre of Oyonnax. The route is mainly a loop. Once you arrive at the lake, you are free to spend as much time there as you like.

An easy hike around Villards-d'Héria with superb views of Lake Antre, the town of Moirans-en-Montagne and Lake Vouglans.Please note that access is currently prohibited: following a landslide, access to the Lac d'Antre viewpoint is prohibited until further notice. From point (2), go directly to point (4). Please note: there has been a forest fire between points (4) and (7) since 17/08/2025 at 7 p.m. Do not attempt this route

This easy hike is best enjoyed in spring and autumn if you want to make the most of the second part, which is also the most beautiful: the waterfall and stream. It's guaranteed to be cool in summer, even with just a trickle of water. Amazon rainforest atmosphere before the waterfall. Moderator update on 24/09/2020: Please note! Change of route at the end of the trail, after the waterfall. To return to the car park, follow the diversion and the yellow markings.

From Matefelon-Granges, I suggest you take a 11 km circular trail through the Ain Valley, then the Oignin Valley. Along the way, you will enjoy views of Thoire, the Château de Coiselet (private), the Saut de l'Oignin waterfall and its potholes, and finally the lake upstream.
