La Roselière: Between Sausset-les-Pins and La-Couronne lies a jewel: the "reed bed", the only wetland on the Côte Bleue. Initially exploited for water supply, breeding and the collection of rushes, it is a wild, natural site, very attractive in particular for the birds which play a major role all year round.
A large valley with a flat bottom called the Grand Vallat valley, which comes down from the Estaque mountain range, leads to the Boumandariel cove.
While the bottom of the valley is occupied by a reed bed, the rest of the biotope is formed by a small beach of sand and rocks bordering the sea.
Further west, in the direction of Tamaris, the coastal rocks are dominated by a hill where the Mediterranean vegetation is very rich.
