Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - Alssundbroen offers some of North Sea Coast's richest channel diving. Water ranges 3-19°C, warmest July, August, September.
Alssundbroen offers a straightforward shore dive, often used for training or a quick local dip. You'll find a silty bottom around the bridge pylons, attracting small crabs and flatfish. Visibility can be hit or miss, typical for inland waters, but it’s an accessible spot for newer divers looking to practice skills or just get wet.
