Diving the Fehmarnsund Bridge

Site Overview

Fehmarnsund Bridge is a wall and reef dive site in Baltic Sea – Schleswig-Holstein (Ostsee), Germany, reached from the base town of Fehmarn. The Fehmarnsund Bridge is a current-swept shore dive where the bridge pylons drop into a kelp-fringed wall alive with cod, pollack and nudibranchs. The tidal flow brings plankton and feeding fish, making it a favourite for underwater photographers and training groups willing to time the slack. The site reaches a maximum depth of 28 m with an average profile around 16 m and a shallow start near 3 m, which places it firmly in the intermediate category and means divers should hold at least an Advanced Open Water certification. Conditions are typical of the Baltic Sea environment: visibility generally runs from 4 to 15 metres, the current is strong, and the water temperature ranges between 6 and 20 degrees Celsius with moderate surge exposure. The marine community is centred on Atlantic Cod, Pollock, Common Cuttlefish, Nudibranchs (Flabellina spp.), Spider Crab, Moon Jellyfish, and the full species list is detailed below for divers planning a trip. The combination of wall, pier topography and rock and concrete substrate gives Fehmarnsund Bridge its distinctive character within the Baltic Sea – Schleswig-Holstein (Ostsee) region. Fehmarnsund Bridge is a strong representative of why German diving is so highly regarded, blending the geology, history and biodiversity that define the country's underwater exploration. It pairs naturally with the other sites of the Baltic Sea – Schleswig-Holstein (Ostsee) region for a varied holiday, and with the right thermal protection and, where relevant, the correct specialist training, it offers a memorable dive for photographers, naturalists and wreck, reef or freshwater enthusiasts alike. As with every German dive, a drysuit and a careful respect for cold-water limits turn a good day into a great one.
