    The Kattegat is one of our favourite wrecks off Bornholm, despite its tragic story. Sunk in dense fog back in '63 after colliding with the Wilke, she lies upright and surprisingly intact at 20 metres. You can really feel the history as you descend, the hull still holding its shape, a ghostly silhouette against the often moody Baltic light. We love exploring the holds, imagining the cargo she once carried. Look for the deck superstructure, it’s a favourite hangout for blennies and the occasional curious cod. The visibility here can be temperamental, but on a good day, the light filtering through the collision damage is genuinely atmospheric. We'd suggest going in late summer for the best chance of decent conditions, and definitely bring a good torch – there are some lovely nooks and crannies for macro life. The Kattegat is a fantastic dive for those who appreciate a well-preserved piece of maritime history and don't mind a bit of a chill.
