Site details

A dive site in France.

wreck

Deep technical dive — the wreck sits on a roughly 58 m seabed, well beyond recreational Open Water and even standard Advanced limits, and sources recommend Niveau 3 Nitrox-confirmed or Tek-certified divers only. The site is only diveable in calm weather and trips can be called off for conditions. Resident conger eels and moray eels around the wreckage present an entanglement/bite risk on close approach.
