Lompnieu walks

This circular route straddling the Séran river is at a moderate altitude and therefore accessible in all seasons. It combines a forest trail with a more open environment, passing by some remarkable sites in Valromey: the Pont des Tines, the Étang des Alliettes, the Belvédère de Châteauneuf and the Puits des Tines.

A walk to discover the highest point of Hauteville-Lompnes and its panoramic views.

A short, quick and very pleasant walk between two passes and along a ridge (Gigimont).

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.

Four viewpoints, of course, are located at the top of the mountains. Expect some steep climbs and significant elevation changes. Be careful, as you will be following mountain bike trails in the opposite direction on part of the route. The viewpoints are at the end: Planachat, Cornillon, l'Haïea d'Amont, and the highlight of the route, the orientation table at the top of the Hauteville Lompnès ski slopes. There, in good weather and with low UV levels, a magnificent view of the Mont Blanc massif awaits you.

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 around the Marais de Vaux lake and its wetlands with the opportunity to admire the Charabotte waterfall.

This is a large circular that allows you to discover the different environments of the Bugiste region. Part of it is dedicated to the Lésines lake and the Marais de Vaux marsh, which can be crossed thanks to the facilities provided. The main part runs along the ridges above Cormaranche, with the climb to Golet Marmier and Planachat, the crossing from Col de la Clye to Col de la Rochette via Gigimont, then the climb to Haiea d'Amont and Cornillon. The descent passes through Notre-Dame de Mazières and Trou de la Marmite.

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.

Open from 1 April to 30 November – subject to snow conditions. The section from the Chalet d’Arvière to Pont de La Loi is the sixth stage of the six-day walking tour “La GTJ from Mijoux”.

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.

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 little-used route offers an original approach to the Grand Colombier, with a rocky final ascent that adds a bit of spice to the hike! Nevertheless, it is manageable for the average hiker. The Chanduraz promontory, overlooking Lake Bourget, is well worth the effort... Not to mention the view from the Granges du Colombier.

The Retord Plateau is ideal for snowshoeing in wide open spaces with, in places and in good weather, panoramic views of the Alps and Mont Blanc. You can enjoy a snack in the picnic room at the Retord farm.

The walk is easy and pleasant in hot weather. It starts at La Bourbellière after Thézillieu; there is little tarmac, and it follows forest tracks and paths that are often shaded. The panoramic view from the belvedere is well worth a visit.
