Best for technical divers, 2-141m, shore entry, strong current.
Source de Marnade is a technical shore dive located in Marseille and Calanques, France, offering a depth range between 2 and 141 metres. This site features an overhead environment that requires advanced technical certification and full redundancy in equipment to manage entanglement risks. Divers must navigate variable visibility that can drop to near zero and contend with strong currents throughout the water column. Due to the complex nature of the caves and swim-throughs, precise gas planning and navigation are essential. The habitat supports various temperate freshwater fish and invertebrates, though environmental conditions often limit observation. This site is strictly for experienced technical divers.
