Hidden off-route spots: The medieval hilltop village of Châtillon-sur-Chalaronne (Dombes region) is 20 minutes off the A6, featuring a covered market and half-timbered houses.

The backbone of this itinerary is the A4 from Vicenza to Turin, then the A5 and tunnel to Aosta. After crossing into France, the A40 and A6 dominate, with toll costs around €65 total.
