Starting from Vizille and the Place du Château, embark on a 58km road bike loop on mountain roads.
At the top, you'll have a magnificent view of Grenoble and the surrounding mountains.
From Place du Château, where you can park your bike, head for Le Péage de Vizille, Bourg d'Oisans on the D101 (approx. 1.5 km).
