At the exit of Aix-en-Provence, take the road for Le Tholonet (D17), the same one that Cézanne traveled on so often. Once in the village of Le Tholonet, in front of "Le Relais Cézanne" (restaurant), take the Route de Langesse (D64e) on right handside. It will lead you directly to the Château Crémade.
