[1] The parish is divided into three areas: the north, composed of schist and carbon greywacke (dating to 360 Ma), the south, characterised by limestone deposits from the Jurassic period (200 Ma), and a narrow area that separates the two composed of reddish sandstones from the Triassic (230 Ma.

Above these carbon cliffs, which comprise the ancient massif, is a plateau of sandstones from the Pliocene (5 Ma.

The Mediterranean climate is heavily influenced by the Atlantic Ocean.

The winters are mild, with little precipitation, but elevated atmospheric humidity, with temperatures starting at 12 °C (54 °F).

In summer, the cool dry air, owing to the winds from the north, maintain temperatures around 20 °C (68 °F).
