    Trolle is one of those sites we always recommend, especially for newer divers looking for a proper wreck experience without the big depths. She’s a motor vessel, went down in a collision back in '47, and now sits in a shallow six metres of water just off Bornholm. You'll find her broken up, but still very much a wreck, scattered across the seabed. The bow section is particularly intact; we love poking around the hold, imagining the cargo she once carried. The ambient light here is remarkable, even on an overcast day, filtering through the water and illuminating the metal. We’ve spent hours just watching the schools of juvenile cod dart in and out of the twisted frames. Those spaces have become home to so many small critters – crabs scuttling in the shadows, blennies peeking from crevices. It’s a busy ecosystem. Trolle is genuinely fascinating, a real piece of history that’s now a thriving artificial reef, perfect for long, relaxed dives and photographers keen on playing with natural light.
