This walk goes through a wide basin, slightly hilly, consisting of a real landscape mosaic. This diversity is related to the sporadic presence of rock and water that allowed the development in certain areas of lush farming. This bucolic landscape is embellished with vast panoramas of the Luberon to the south, the Lure mountain to the north and the Alps to the east. The villages, with their well marked outline, are located on rocky spurs on the outskirts of the valley.
