From Palazzo Canavese you roll out toward the Serra di Ivrea nature reserve, then follow the Canale Depretis and the Naviglio di Ivrea as the route unfolds. The Lago di Viverone nature reserve comes next, before the castle Castello d'Harcourt rounds things off. With 743 m of climbing across 60.7 km, it's a steady day out, and the loop brings you back to Palazzo Canavese where you started.
