La Cathedrale - Marseille & Calanques
La Cathédrale is a dive that truly lives up to its name, an impressive cavern system just outside Marseille. You’ll find large, open chambers with light filtering down from the surface, creating an ethereal glow. It's a great spot for advanced open water divers comfortable with overhead environments, offering a unique architectural dive rather than a coral-focused experience. Bring a torch to explore the darker corners, though much of it is well-lit by the entrance.
