The *Blue Mist* is one of those wrecks we keep coming back to. No, it's not a massive freighter, but this sailing vessel, sunk by an explosion in '74, just has a certain charm. Sitting upright in only 18 metres, it’s a brilliant dive for those looking for a relaxed exploration. The visibility here can be surprisingly good, letting you see the whole shape of the hull as you descend, a dark outline against the blue. We love finning slowly along the deck, imagining the final moments. The explosion ripped through the stern, leaving a dramatic tangle of metal and twisted wood. It's an easy swim around the whole structure, and you'll find clouds of damselfish flitting in and out of the broken mast sections. Look closer in the shadows; moray eels often peer out from under the collapsed decking, and the hull is now home to countless tube worms. Our favourite trick is to go early, before the dive boats from Marseille clog the surface. It gives the wreck a quiet dignity it deserves. Bring a good torch; the interior, though small, offers some interesting dark corners for curious eyes. It’s perfect for divers who appreciate history and don't mind a compact, characterful wreck.

Cause
unknown
The story of the Blue Mist is one of sudden violence and lingering mystery. In July 1974, this sailing vessel was cruising in the beautiful Marseilles Bay when it was torn apart by a massive explosion off Port du Frioul. The vessel sank immediately, leaving questions about the cause of the catastrophic event unanswered to this day.
Located at a very manageable depth of 18 meters, the wreck is accessible to most certified divers, but it comes with a significant warning: it is classified as a 'Dangerous Wreck'. The force of the explosion likely left behind a chaotic field of sharp, twisted metal and potential entanglement hazards. Cautious divers will find a fascinating, if somber, site to explore, piecing together the vessel's final moments from the scattered evidence on the seafloor.
