The massif of the Estérel has a fertile ecosystem of birds, mammals and insects of all sizes. Stags and hinds are the main attraction, but it is also a paradise for entomologists and bird lovers. The region is home to hundreds of birds of prey and a range of other bird species from common to rare.

The multitude of habitats also supports remarkably diverse vegetation representative of the Mediterranean ecosystem. Oak groves and pine forests thrive, while the invasive mimosa is closely monitored to prevent its proliferation.
