Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - BJORNO offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
Bjornø isn't a dive you pick for dazzling corals, but it offers a fascinating glimpse into history, a stark, often dramatic dive in the North Sea. The wreck itself, a dangerous tangle of steel, lies in just 11 metres, making it accessible to many, though we’d suggest some solid cold-water experience. We love how the sea has truly claimed this site, turning the wreckage into an artificial reef, dark and full of character. Descending onto Bjornø, you’re met with a silhouette of steel, often shrouded in that atmospheric North Sea green. Visibility can be a challenge here, sometimes dropping to a few metres, which only adds to the wreck's eerie charm. Our favourite moments are picking out the details of the ship's structure, seeing the robust plating and the way marine growth has softened the edges. You'll spot crabs scuttling through the crevices, and various fish flitting in and out of the shadows. It’s a dive for those who appreciate the story beneath the waves, for wreck enthusiasts who don't mind a bit of a current, and for anyone keen to experience a slice of Danish maritime history, wild and untamed. Go on a calm day, and bring a good torch; it makes all the difference.
