Sonthonnax-la-Montagne walks

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!

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

An alternative route from Granges to Heyriat, descending to Bonbois. This path is in better condition than the descent near the chapel. This route takes a short detour to the Pisse-Vache waterfall, which is featured in guidebooks. It is interesting during rainy periods but only a trickle of water when the previous weeks have been dry. Return via the village of Bonbois and along the River Ain.

A magnificent hike with panoramic views of the Ain and the Jura plateaus, caves and waterfalls.

A lovely educational trail for families with two viewpoints overlooking the Ain valley.

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.

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.

A variation on the classic Mont Balvay hike, with a detour via Vers. This route offers a different perspective with a route across the plateau from Vers. The climb up to Vers through the woods is pleasant, well marked and picturesque. The descent to Napt is also very enjoyable.

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.

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.

Hike on the heights overlooking Lake Nantua with beautiful views of the lake. The areas sheltered under the trees provide respite from the summer sun. The hike can be rounded off with a refreshing dip in the lake. Some sections are a little technical.

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.

Hike with panoramic views of Lake Nantua and the cliffs in the first part, then descend along the Landéron, which you will cross twice.

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.
