Aix-en-Provence to Cassis: Ultimate Road Trip Guide

The 18-kilometer route from Aix-en-Provence to Cassis follows the D9 and D559 roads, passing through the Massif des Calanques’ northern fringe. This limestone massif, formed 120 million years ago in the Cretaceous period, creates a dramatic transition from Aix’s sun-baked plains to Cassis’s turquoise coves. The drive typically takes 25 minutes without traffic, but the hidden calanques demand exploration.
