    StandoutRich in charismatic marine life

    The Dalton sits in serious depth off Medes, a proper technical dive at 45m. We love it because it’s a wreck with real history, not just some random pile of metal. She went down in 1928, a steamship carrying ore, and you can still make out the bones of her, even though she’s well-colonised now. Dropping down, the visibility here often pushes 20 meters, letting the full length of her, 71 meters, slowly materialise from the blue. The compound engine is a highlight, and we always spend a bit of time picking out the details on the stern. Over the decades, schools of barracuda have claimed the superstructure, and if you hover quietly, you’ll often see dentex patrolling the edges of the wreck, sometimes surprisingly large ones. It’s a dive for those comfortable with deeper profiles and a bit of current, which can sometimes sweep through. We’d suggest going early in the morning for the best chance of calm conditions before the dive boats from L’Estartit really start moving. It’s not an easy dive, but the sense of history, paired with the marine life that has made it home, makes it a standout for us.
