Lhuis walks

Starting from Cerin, this mainly wooded marked trail takes you through several valleys with streams offering several waterfall passages. After rainy weather, the waterfalls are magnificent but the ground is then more slippery.

Circuit of the Chosas and Brive waterfalls, starting from Marchamp via the Lac de Cérin, the fossil quarry, the Palaeoecological Museum via the "sur les traces des carriers" (in the footsteps of the quarry workers) trail and the old mills.

Passing over the Cols du Grand and Petit Pertuis, you'll be amazed by this route along the ridges, which offers 360° views of the Alps, Massif Central and Jura. An easy hike for regular walkers.

A lovely, gentle walk, part of which is along the Rhone, which you can do as a family.

A beautiful hike, fairly well marked in blue with directional signs (sometimes a little faded), between 630 and 900 metres above sea level, easy, mostly on good, well-shaded paths. On very clear days, there are views of the snow-capped Alps and the villages of Marchand and Cerin. For flower lovers, between May and July, there are martagon lilies, orchids, snowdrops and erythronium. And for those who like the cool air, they can go to the Grotte de la Jaquette cave near the path.

An all-season looping route in the Bugey region, starting from Colomieu. Taking in the Furans and Gland basins, it is a pleasant walk with its marshes and lakes, and an original one with its passage through the Roche Percée de Corne-Bœuf. Beware of water levels, which can vary considerably. Diversions to (13). Moderator on 06 June 2025. Pending action by the author.

This is a very beautiful hike, especially after a few days of rain, which feeds the many streams. The first part up to (1) is not very steep but quite long, so it is best to be in good shape.

This trail allows you to discover the three rivers: the Tréfond, the Arodin and the Perna(z), the biodiversity of the site, and its geological and heritage riches, explained by six information panels.

A marked trail allows you to explore several water-related areas (hillside, stream, marsh) around Glandieu and its waterfall. Some paths are not maintained, see notices.

A lovely walk starting from the banks of the Rhône, leading to the Mont de Cordon viewpoint (altitude 400 m) and offering a beautiful panorama of the Rhône and the Izieu mountain. During the climb, you pass a beautiful private castle and on the way back, you can see three caves that were inhabited during prehistoric times: the Bonne Femme cave, an unnamed cave and the Liévrin cave.

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

This is an easy, well-known walk that allows you to discover the surroundings and heritage of Saint-Chef. In particular, it takes you past the abbey church.

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 loop starting from the village of Grésin allows you to discover the site where the Italian engineer Galetti installed his harp antenna. Today, the site on the edge of a cliff offers a beautiful view of the Rhône canalised between the departments of Savoie and Ain. It then follows a section of the Way of St James. The route is dotted with shells, of course, but also with stone and metal crosses.

A very pleasant trail from Saint-Sorlin-en-Bugey leads first to the old village of Souclin and then to the Roche de l'Église, which overlooks it. This hike will appeal to lovers of old stones: old villages and paths often lined with timeless stone walls. This route has few paved roads and offers many panoramic views of the Rhône between Bouvesse and Vertrieu, the north of the Isère and, in good weather, even Lyon.
