A gentle start along the Isère which will lead you without difficulty by the Col de la Placette to dominate the hills of Valdaine and the blue waters of Lake Paladru.
From Grenoble, from the Quai de France, take the lane on the bank of the Isère right bank to the Veurey Bridge. After the bridge, join Voreppe by taking the Roise footbridge on the right.
In the village turn left on the D520 and attack the Col de la Placette (the climb is pleasant thanks to the corridor fitted out for cycle tourists). From the pass, go down to the Demay bridge and turn left towards St-Etienne-de-Crossey, then in the village take the D49 opposite towards St-Nicolas-de-Macherin and Chirens by a small portion of the D1075.
At Chirens, turn left towards Clermont and Colletière and take the D50d to reach Paladru and follow the lake towards Charavines. Shortly before Charavines, turn right on the D50e towards Oyeu, then left on the D520e towards Colombe and Rives, and finally left towards Renage.
Descend towards Tullins along the Fure, in the village, take the D1092 at the traffic lights on the right, and then shortly after on the left take the D45 in the direction of St-Quentin-sur-Isère.
Before the Isère Bridge, find the cycle path on the bank on the left for a return to Grenoble by the opposite route.
