This is a very popular hike to the Croix du Reculet, the second highest peak in the Jura, offering superb views of Geneva, Lake Geneva, Mont Blanc and the entire Alps in good weather. For geocachers, there are a few caches along the hike.

Hiking on the lower Jura mountains, on wide paths through fields and forests, connecting the heart of two villages in the Pays de Gex, partly following an ancient Roman road. Throughout the hike, you will see old buildings (Gex farms, castle, churches), views of the Pays de Gex plain, and further afield, the Salève, the Alps and Mont Blanc in particular. This route can also be done by mountain bike.

Erratic boulders transported by the Rhône Glacier to the foot of the Jura.

From Saint-Jean-de-Gonville, I suggest heading up to the Monts Jura and its higher ground: after climbing to the summit of Le Reculet, the route continues along various ridges to the Passage des Chézerands, offering some lovely views. Navigating unmarked sections, walking on steep or even very steep slopes, and a fairly exposed but avoidable section are the main difficulties.

A walk that varies between forest paths, following streams and crossing vineyards, and the old village of Dardagny.Can also be done by mountain bike (except for one section - from point (7): bypass via Essertines).

This circular route, just a few kilometres from the city, immerses you in nature in a surprising way, allowing you to discover two rivers in the Canton of Geneva, then the vineyards of Dardagny. It can be done in either direction.

A short walk along the river that offers a gentle invitation to slow down and reconnect with the landscape. From the moment the path meets the water’s edge, the steady flow of the river sets a calm rhythm, guiding each step forward. Sunlight glints on the surface, shifting with the breeze, while reeds and grasses sway quietly along the banks. Even in familiar surroundings, a riverside walk can feel like a small journey, revealing subtle changes in light, sound, and colour as the route unfolds.
