The Aschau Lagune is a nice area for some mixed birding. The lagoon, beaches and offshore areas can hold many species of waterbirds. Most species of dabbling and diving ducks can be seen here and many geese rest on the meadows.
During winter a large population of Razorbill enter the bay daily to feed and can be observed together with loons and diving ducks when sea watching from the dunes.
Access by public transport possible (Bus stop Aschau-Altenhof bei Eckernförde). Parking available. Nice bike ride from Kiel and Eckernförde
