Vieu walks

This loop allows you to visit several characteristic sites in this area where the folds of the Jura meet the alluvial plain: the sharp limestone pavement of Fierloz, the Cerveyrieu waterfall, the Turignin Gorges on the Séran, the sources of the Groin and the chasms it forms. In high water, the route can be slippery but it is impressive.

This is a fairly strenuous hike, but without any major difficulties. The climb is very steady, with no respite. From the Grand Colombier, there are beautiful 360° views.

A pleasant ride on an electric mountain bike.Waterfall, Marmites des Géants, lake and castle are all on the agenda.

This is a fairly long hike, which starts off easily along the Arène but quickly becomes more challenging when you leave the D53 to reach the Sérémond viewpoint. The beautiful view at the top is well worth the climb. The second part is easy and descends back to the village, partly following the same path used on the way up.

The hike starts in Béon and aims to reach the summit of Grand Colombier (1,534 m) with a quasi-circular route. It can be classified as somewhat challenging due to the elevation gain and distance covered. The ascent includes a few fairly steep slopes overall. Otherwise, there are no major difficulties (at most, it should be noted that orientation can be a problem around point (9) and that the markings are less precise at the end of the route).

Hike from the Chalet d'Arvières with a gradual, shaded climb to the Col de Charbemènes. Then follow the marked trail, which will take you to the Grand Colombier at 1,525 m in about an hour. You will then have a magnificent view of the Alps, Mont Blanc, Lac du Bourget, the Rhône, and more.

To complete the hike (Le Grand Colombier from the lodge d'Arvière n°1241202), you can extend it from the pass by returning via the Griffe du Diable and Grange d'en Bas ridges. This trail is less frequented than the one leading to the cross and then to Le Grand Colombier itself, offering you more distant views. Best done in good weather without snow, this trail seems less suitable for snowshoes.

Circular trail exploring the Lavours Marsh and its nature reserve, via the boardwalk, then along the Séran river before climbing the Courbettes hill to return to Ceyzérieu.

A beautiful hike at the foot of Mont Colombier, with panoramic views from the start and of Mont Blanc at the summit. Bucolic landscapes and pastures.

A short walk to discover this Sensitive Natural Area, with 2 km on stilts. Numerous information panels and superb views of the Grand Colombier.

A summit and vistas in a site dominated by pastures.

At the southern end of the Jura mountain range. A scenic route from Sur Lyand to Grand Colombier and back via Les Crêtes.

This hike is based on the 4 belvederes walk. The route has been modified to take into account the opinions of hikers who have given their feedback. In particular, the trail is more precise and the parts considered less interesting have been removed. We are delighted with this new version, which is particularly suitable for hot days (tested during the heatwave of August 2025).The route is mostly through woods and on unpaved paths or tracks. It offers splendid panoramic views from various viewpoints as well as iconic sites: Trou de la Marmite, Notre-Dame de Mazières Chapel, etc. On a clear day, you will have the pleasure of admiring Mont Blanc.

An easy route to discover the Bas Bugey. Pass by Lac de Barterand, a small, refreshing lake (fishing and swimming), Marignieu with its wines, honey and an almost 800-year-old chestnut tree, and the nearby Marais de Lavours with its discovery trail. Not forgetting Vongnes, its Bugiste wine cellar and the Ecomuseum on the trades of the vine and wine.

Pleasant, shaded hike Few markings at the start of the route, yellow markings in the undergrowth, cairns to cross the stone plateaus.

This is a very beautiful hike, featuring landscapes of pastures and beech and fir forests, along easy paths. Created in partnership with the Museum of Resistance and Deportation in Nantua, it passes by five farms where the maquis settled in 1943-1944, on the Retord plateau between the village of Hotonnes and the Plans d'Hotonnes resort. Five panels describe the history of this maquis.

A short walk for a half-day outing from the tourist village of Chanaz. In the village, directional signs clearly indicate the Circuit de Pierre Noire. Lovely viewpoint over the village and its canal, the Rhône river developments, Mont Colombier, etc.

An autumn walk in the Avant Pays Savoyard, to see something other than mountains, even if Mont Colombier is omnipresent throughout the hike.

An easy walk with beautiful views of Chanaz, then Lac du Bourget on the Chemin de Pomey.

This is a short circular loop on the eastern edge of the Bugey, which allows you to discover a curiosity: arches and a path carved into the rock at Écorche-Bœuf, then a few glimpses of the Alps as you descend from the Col de Richemont.
