Diving Le Dalton

Site Overview

Le Dalton is a wreck and reef dive site in Provence & Calanques, France, reached from the base town of Marseille. Le Dalton is a wreck in 18-30 m off Marseille, now an artificial reef rich in macro life and small fish. It is shallower than the city’s big wrecks, making it a good intro wreck for intermediate divers. The site reaches a maximum depth of 30 m with an average profile around 20 m and a shallow start near 14 m, which places it firmly in the intermediate category and means divers should hold at least an Advanced Open Water certification. Conditions are typical of the French coastal coast: visibility generally runs from 12 to 28 metres, the current is mild, and the water temperature ranges between 14 and 25 degrees Celsius with low surge exposure. The marine community is centred on Conger Eel, Two-banded Seabream, Common Octopus, Common Cuttlefish, Mediterranean Cardinalfish, Dusky Grouper, and the full species list is detailed below for divers planning a trip. Le Dalton is a strong representative of why Provence & Calanques diving is so highly regarded, blending the geology, history and biodiversity that define French underwater exploration. It pairs naturally with the other sites of the Provence & Calanques region for a varied holiday, and with the right thermal protection and, where relevant, the correct specialist training, it offers a memorable dive for photographers, naturalists and wreck or reef enthusiasts alike.
