SEINE
Why dive here
With 50+ marine species recorded in the area - including dwarf minke whales and jellyfish lake - SEINE offers some of Baltic Coast's richest wreck diving. Water ranges 1-17°C, warmest July, August, September.
The Seine is a dredger that capsized and sank while under tow back in 1927, now resting upright at 28 meters. You’ll find her 13 miles southwest of Utö, and she's surprisingly intact, offering plenty of nooks and crannies to explore. It’s a proper wreck dive, with that eerie, historical feel you get from old vessels. Visibility here can vary, but on a good day, the structure itself is quite striking, attracting cod and wrasse that dart in and out of the metalwork. We’d say it’s best suited for experienced divers comfortable with deeper wrecks and cooler water.
