France
If you're planning to drive in France, consider avoiding the toll roads and taking the local roads instead. Toll roads are quick but they are deadly boring and expensive - they add a lot of euros to the price of your holiday. Local roads are more interesting to drive and allow you to discover France's best hidden gems: ancient churches, vineyards and olive groves, winding rivers and fantastic bakeries. Be careful though: exploring the backroads could be so much fun that you don't leave time to reach your final destination!
