Les Rosiers

Les Rosiers sits offshore at the seaward edge of the Baie de La Ciotat, southeast of Île Verte. Land shelters it through the northern half of the compass: Île Verte and the town lie immediately NW-N, the Bec de l'Aigle / Cap de l'Aigle massif blocks the W-WSW, and the eastern arm of the bay shadows the NE-E — so the offshore-blowing Mistral (NW-N) and easterly winds reach it only weakly. The exposed window is the open Mediterranean to the SE-S, which is fully open, with the SE-SSE sector taking the brunt of any sea. Because it stands unprotected in this seaward gap, a Libeccio (SW) or Marin/Scirocco (SE) blow, or any open-sea swell, quickly builds surface waves and chop over the rock — the reason this "most exposed" of the Pierres du Large is only diveable in genuinely calm weather.
