The Terrain des Peintres is a wonderful terraced garden perfect for a picnic, from where Cézanne, among others, painted the Montagne Ste-Victoire. The view of the jagged mountain is inspirational. The gardens are opposite 62 av Paul Cézanne. You'll find it a 10-minute walk uphill from the Atelier Cézanne stop (bus 1 or 20).
