La Grotte à Corail

The site lies on the south-facing limestone cliff front of the Calanques massif west of Cassis, so the towering rock wall to the north blocks the dominant Mistral (NW), which is exactly why the dive is reliably sheltered and beginner-friendly. The open exposure is to the south and southwest, where Libeccio (SW) and the long-fetch Scirocco (S–SE) build the wind-waves that reach the coast. The eastern sectors are partly shadowed as the coast curves back toward Cassis and Cap Canaille; being a microtidal Mediterranean cavern, swell is modest but surge inside the vaults amplifies when a southerly is running.
