The first part of the itinerary has a natural charm. The ascent to Allières is rewarded by the arrival at the castle, followed by the panoramic view from the descent. The crossing of the village of Claix brings your walk to a pleasant close.
The shopping center parking lot, the starting point for your journey, is centrally located on the Avenue de la Libération (D1075). It's right next to the Pont Rouge and Pompidou bus stops, served by buses 21, 25, 47 and 48.
You quickly leave the center of Pont-de-Claix to join the Promenade Joseph-Marius Thiervoz and then the Chemin de la Digue, safe, shaded paths that take you along the Drac to Varces. You then gain altitude and reach Allières before a beautiful descent that takes you to the center of Claix, the final stage before returning to your starting point. Balanced between cycle-friendly sections and less-travelled roads, this route is ideal for amateur cyclists.
