Around Oignin

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!
Petit tour de Granges à Heyriat

Je vous propose un petit parcours permettant de rejoindre Heyriat à partir de Granges situé pas très loin des bords de l'Ain.
From Saint-Maurice d'Echazeaux to Montdidier Castle

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.
Overhangs of the Ain Gorges: Bolozon - Balvay - Solomiat - Napt

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 Jarbonnet Rocks

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.
Overview of Nantua

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.
Roche d'Au-Delà

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.
Hautecourt Cave Loop

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.
The Pic d'Oliferne

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.
Molard de Netru from Chancia

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.
Semine Valley

A refreshing short hike with multiple panoramic views.
Tour of the Cerdon heights

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 before returning to the starting point via the Combe Cugnat and a slight detour via Mont Carmier.
Please note: access is currently blocked at the Pont de l'Enfer (11) and therefore indirectly from Labalme (8). An alternative route avoiding this area is suggested. See below.
Mont Rignat and the springs of the Reyssouze

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.
La Quinquenouille and Dramelay

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.
Ferme du Crime - Lake Antre

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