You'll not only be attracted by the magnificent beaches of the Flensburg Firth holiday region; its underwater world also has a lot to offer: In addition to the varied plant and animal life, numerous wrecks are also waiting to be discovered on your dives. Tours of these wreck sites are also available. The historical background to this is also gripping. This is the location of the “Rainbow Campaign” in which more than 60 submarines were sacrificed towards the end of the war. Many of them were lifted, some were bombed – some remnants remain at the bottom of the sea.
