We have travelled from Portugal to Perpignan on Spain’s toll free roads. We are now looking at route options to Chatel to meet up with family and friends at the weekend. Google maps are quoting 4 hours difference (only a few miles difference on mileage) between taking the toll road via Annecy or the D roads and I understand the cost is over €100. So does anyone have any tips or tricks for this route, is there are particular part to avoid and take the toll?
