La Buisse walks

This low peak and its twin opposite on the Vercors side, the Dent de Moirans, watch over the exit of the Isère as it flows quietly towards the Rhône and the entrance of rain and snow clouds pushed by the north winds. A remarkable viewpoint over the valleys, it is an ideal half-day walk.

A beautiful loop around the Grand Ratz, passing by the Roche Brune viewpoint with its breathtaking view of the Isère valley.

A lovely but fairly strenuous hike. Return via the same route.

A challenging and demanding hike through the impressive scenery of sheer drops and cliffs typical of the Chartreuse foothills, ancient high-altitude meadows, and a descent into the torrential basins of Charminelle and La Roize, passing through the peaceful haven of Chalais Monastery before returning to the starting point.

A very beautiful route for exploring Voiron and its surroundings, with stunning views over the Grenoble valley, the Chartreuse, the Vercors and Belledone.

An easy hike to discover the statue towering above Voiron. A real treat, especially in snowy weather. The statue of the Virgin Mary was erected in honour of the Iron Virgin of Le Puy-en-Velay. Legend has it that Bonnassieux committed suicide after sculpting the Virgin. However, he did not commit suicide and died with honours. He deliberately placed Jesus in her right arm so that he would not hide his mother's face as she blesses the town

This walk is ideal for families. It gives you an insight into the age-old struggle of the people of Voreppe against the flooding of their two main rivers, the Roize and the Isère.

As you pass through the hamlet of Gachetière, the original village of Voreppe, you can catch a glimpse of the ruins of Château Vieux, the former Dauphin’s castle.

This walk, starting from Voreppe, takes you through a few old hamlets of Voreppe, through the woodland and along the Roize torrent. The Roize torrent is one of the most powerful in the Chartreuse. In mid-May, it wasn’t showing off its full power. The Roize has powered a number of facilities: mills, sawmills and tanneries, and has helped make Voreppe a small economic hub in the Isère valley.

This peaceful walk passes through the hamlets of the plain.
