If you are not afraid of driving in the mountains, you should go by D99, heading west. Then go by D27, heading south. This route twists around between the summits of les Alpilles, and from here one overlooks the Val d’Enfer (Hell’s valley). It is a very beautiful trip, but one must be aware that the road is very narrow. On one side there are steep cliffs and on the other side the deep abyss, so take care.
