Wreck of Mars
Why dive here
With 66+ marine species recorded in the area - including jellyfish lake - Wreck of Mars offers some of Bornholm's richest wreck diving. Water ranges 3-18°C, warmest July, August, September.
Forget your usual warm-water wreck dives; the Mars is a different beast entirely. Lying off Bornholm, this isn't just a sunken ship, it's a cold-water time capsule. We're talking about a 16th-century Swedish warship, mind you, and the sheer scale of it hits you first. As you descend, the sheer timbers emerge from the gloom, still holding the ghost of battles long past. Our favourite part has to be finning past those ancient cannons, often draped in kelp, with the occasional cod peering out from a dark corner. The visibility here can be tricky, so pick your day carefully, ideally with minimal swell. When it's good, though, exploring the intact sections of the hull, still bristling with artefacts, is an incredible experience. You'll often find ling and conger eels making homes in the deeper parts of the structure, and the occasional curious seal might even join your dive. It’s a dive for those who appreciate history and don't mind a bit of a chill; a drysuit is definitely recommended. It’s a privilege to see a wreck this old, this well-preserved, and still relatively untouched.
