Tornowsee - Bornholm

Blue Water Diving Safari isn't a single spot, it’s more an experience we chase off Green Island’s eastern flank. Think open ocean, big pelagics, and a feeling of genuine wildness. We’re talking about drifting along a deep blue wall, often with a decent current pushing you, so it's one for those comfortable with their buoyancy and a bit of movement. What makes it standout? The sheer scale of the place. You often drop in over a deep reef, then drift out into the blue. We’ve seen oceanic triggerfish here, big schools of fusiliers, and once, a fleeting glimpse of a hammerhead way down deep. The feeling of being suspended in that limitless blue, with the sun's rays spearing down, is something we really love. Our pick for a top day here is to go early, before the thermocline settles too deep, and keep an eye out for those bigger shapes materialising from the gloom. It's a proper adventure dive, not one for just admiring static coral, though the wall itself has some impressive hard corals, particularly brain coral and sprawling staghorn formations.
