Parsteiner See - Bornholm

Lagoon Mounding isn't about dramatic drop-offs or roaring currents. It’s the kind of site we return to when we want to slow down and really look. Think of it as a sprawling, sandy treasure hunt. We’re talking about a shallower, protected lagoon environment where the true stars are often overlooked in more 'exciting' places. We love spending time here just poking around the sand and rubble patches. This is where you’ll find an incredible concentration of shell life; Variable Strombs and Maldive Cones are everywhere, but keep an eye out for the more elusive Triton's Trumpets. The visibility is usually excellent, letting you spot a Blue-spotted Stingray half-buried in the sand, or the delicate movements of a Little Post Horn Squid. It’s also fantastic for wrasses – Goldbar Wrasses zip past, and the Spottail Coris are always a joy to watch. It's a photographer's dream for macro and wide-angle shots of the calm, sun-dappled bottom. Our favourite time to dive it is late morning, when the sun is high and brings out all the colours.
