Best for expert divers, Up to 60m, shore entry.
Source de l'Esperelle is a shore-entry cave dive located in the Marseille and Calanques region of France. This technical site features a complex overhead environment that descends to a maximum depth of 60 metres. Due to the nature of the cave, divers must possess full cave certification and technical diving competence. Conditions are variable, with unpredictable currents and visibility that can drop to near zero within the cave structure. Divers should carry redundant lighting, a primary reel, and safety reels. Strict buoyancy control and careful navigation are required to manage entanglement risks and avoid disorientation in this challenging, lightless environment.

A shunt discovered in 2002 allows divers to bypass a difficult, narrow section of the cave, avoiding a tedious portage.
