Here is a tip that maybe has more value than the one above. Buy and use Michelin maps only! They are the best. Not only do they give the best information, scenic routes are marked with a green line. Over 35 years of experience has learned me that wherever Michelin draws a green line, it is indeed beautiful. Wherever that line stops, immediately the scenery becomes less interesting. That's why I choose Michelin maps for all destinations. Even in faraway countries like Marocco it was true: green is stunningly beautiful. You can count on it.
