It starts in Marseilles and finishes in Nice. Total trip distance: 640 km.
Provence region is plenty of what to see and to do. If you have your own car, one week should allow you to comfortably cover the highlights. Provence is a place for soaking up atmosphere, rather than racing from sight to sight.
