    Sjaelland off Bornholm is a shipwreck dive with plenty of history. The wreck sits upright, largely intact, offering swim-throughs into the cargo holds if you’re comfortable with overhead environments. We’ve seen cod and flatfish around the structure, occasionally a conger eel peeking from a crevice. It’s a solid dive for those who appreciate maritime history and are comfortable with cold water wreck diving.
