From the start, follow route no. 4 to "Les Guillets", then descend through the village of Novalaise. The itinerary is rolling, climbing up to the halfway point, then taking advantage of the slightly technical descents to reach the village of Ayn. The link between the Col de la Crusille (572 m) and the Col du Banchet (590 m) is shaded by forest. At Banchet, a beautiful viewpoint invites you to take a break. At Ayn, plunge into a small combe before climbing back up... hard. A short turn onto a plateau with an unobstructed view, and you're off again for a descent that will remain in your memories.
Rejoin circuit N° 3 at the end of the route to cross the Nances forest, making sure you follow the direction of traffic!
