The Montagnette is a 6 000 ha massif whose relief is of low altitude (150 m approximately), but relatively abrupt. Dating from the Neocomian secondary era, 70 million years ago, it is marked by a series of hills and valleys essentially oriented north-west / south-east, parallel to the axis of the mistral. With a significant agricultural and pastoral activity, the Montagnette massif has a relatively low afforestation rate (30%), mainly composed of Aleppo pines.
