Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - U 20 offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
The U 20, a German submarine from the Great War, lies off the Jutland coast. It’s a historical dive, more about the story than the structure itself, given it was blown up in 1925. What’s left is scattered debris, a skeletal outline really, rather than a full wreck. Visibility here can be a bit variable, typical of the North Sea, but on a good day, you can make out some of the larger sections. We've seen some decent crabs tucked away in the twisted metal, and the occasional cod patrols the area. It’s a site for those interested in maritime history and the enduring legacy of these vessels.
Safety Notes
