A local boat operator is the practical way to reach the wreck and time the dive to the weather.
The Dalton is a well-known Planier wreck off Marseille, broken across a rocky field and best suited to experienced divers. The bow sits in rubble while the stern, engines, and boiler remain recognizable, so the dive moves from wreck debris into a clearer hull outline. It is a boat dive that rewards calm seas, good buoyancy, and comfort around depth and wreck structure.
