Thoirette walks

A pleasant, easy circular walk, mainly through woodland. The charming church of Saint-Maurice-d'Échazeaux (or des Chasaux), which overlooks the confluence of the Valouse and Ain rivers, and the ruins of Montdidier Castle are worth exploring.

Je vous propose un petit parcours permettant de rejoindre Heyriat à partir de Granges situé pas très loin des bords de l'Ain.

The route follows the course of the Oignin river on the edge of the Gorges de l'Enfer, then goes around the Lac de l'Oignin, all with some pretty nice scenery!

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.

This is a circular route from Bolozon, passing through pretty villages (Balvay, Solomiat and Napt) and overlooking the Gorges de l'Ain. This is a "classic" route (often suggested in the opposite direction) that does not present any major difficulties.

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.

After an initial wooded section, you will be rewarded with a beautiful view of the Ain river valley from the top of the Jarbonnet rocks. The river winds its way through the valley below. The summit is not very popular and is mainly known to climbers who enjoy the routes offered by the cliff.

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.

A panoramic walk overlooking the town of Nantua and its famous lake, in an exceptional environment that alternates between countryside and coniferous forest. The mountainous route retains a good sporting aspect.

A beautiful, moderately difficult hike with panoramic views overlooking Lake Nantua and the Autoroute des Titans. At the summit, weather permitting, you can see Mont Blanc.

Short loop passing through the Hautecourt Cave Nature Reserve. Hike with no technical difficulty, alternating between woodland and open spaces. The climb up to the Mont Rosset plateau is a little steep, watch out for cows, but you'll be rewarded at the end. Please note that the cave itself is not open to visitors, even though it was France's first underground nature reserve in 1980. Don't be disappointed, though, as there are a dozen information panels on the surface explaining the cave's biodiversity and its exploration in the past. For those interested, there is a 3D tour on the LPO Aura website.

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.

A refreshing short hike with multiple panoramic views.

Walk in the Revermont between Revonnas and Ceyzériat via the Montagne Noire. Beautiful view of the plain and, to finish, a detour to the Ceyzériat waterfall.

A beautiful loop passing through a small, easy, unobstructed peak offering a wide panorama of the Bugey, the Bresse plain, the Beaujolais mountains and the Lyon region. The springs of the Reyssouze reward us at the end of the hike.

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

The aim of the route is to complete a beautiful loop overlooking the Cerdon: after crossing the vineyards overlooking the valley, the route continues on the plateaus of Saint-Alban and Labalme, returning to the starting point via the Combe Cugnat and a slight detour via Mont Carmier.

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

The view from the lookout point is always impressive. Along this trail, you will overlook the beautiful landscapes of Lake Vouglans, observe its colourful surroundings and contemplate its wooded shores, remarkably preserved from unsightly urban development. This route is also suitable for trail runners.
