Introduction: From Alpine Peaks to Mediterranean Shores
The drive from Chambéry (elevation 270 m) to Sète (sea level) spans 380 km via the A43 and A9 autoroutes, typically taking 4 hours without stops. However, the real adventure lies in the 90 km section between Grenoble and Orange where the route follows the historic Route Nationale 7 — often called the 'Route des Vacances' — punctuated by the dramatic descent from the Vercors Plateau into the Rhône Valley. A local driving quirk: the A43 through the Chartreuse massif has several sharp tunnels requiring speed reduction to 90 km/h, and mist can suddenly reduce visibility even on clear days.
