Historically and culturally, the commune is in the Aspres region, a small Roussillon territory between the Têt valley in the North and the Tech valley in the South.

Exposed to a principally oceanic climate, it is drained by the Canterrane and Ample rivers, and various other smaller ones. The commune has a remarkable natural heritage made up of three natural areas of ecological, faunal and floral interest.
