NABU Water-Bird Sanctuary Wallnau
Extending over almost 300 hectares, the NABU Water-Bird Sanctuary Wallnau on Fehmarn's western coast is one of northern Germany's most valuable regions in ecological terms. Here, you can experience bird life at first hand from observation huts that allow you to get within very close range of these shy creatures, unnoticed. A 10-metre-high viewing tower provides a bird's eye view of the area. Different interactive stations along the "Path of the Senses" invite you to explore the natural surroundings. An exhibition provides detailed information about bird-flight. More information is available here
Equally accessible for visitors is the 134-hectare "Grüne Brink" on the north coast of Fehmarn. This strip of land measuring 2.5 kilometres long and up to 180 metres wide that lies between the dyke and the Baltic Sea was only created when the dyke was constructed in 1872. Changes in the currents created eskers, which subsequently formed small enclosed inland lakes that gradually silted up. Today, the Baltic sea water only flows into the little lagoons during flood tides. Over the course of a year, up to 170 species of birds can be seen here.
Krummsteert / Sulsdorfer Wiek
The "Krummsteert" (a word from the local German dialect that means "crooked tail") is situated at Fehmarn's south-western tip and is off-limits to humans. It is part of the "Krummsteert - Sulsdorfer Wiek" nature reserve, which extends over some 300 hectares, including parts of the Baltic Sea. It is made up of four different eco-systems: a spit peninsula - the "Krummsteert", a shallow bay around salt-water marshes with salt-water ponds, and a former bay reclaimed by the construction of a dyke.
