The peninsula is a geologically active sand spit that is constantly reshaped by currents, moving noticeably over decades.
It supports a unique transition habitat known as a 'Salt Marsh' or 'Salzwiese', which tolerates occasional flooding by brackish water.
The reserve is a critical stopover on the East Atlantic Flyway for migrating birds moving between the Arctic and Africa.
The iconic thatched-roof houses located at the base of the peninsula are private property and sit on a narrow strip of land protected by dikes.
During the nesting season, large portions of the reserve are strictly off-limits to humans to protect ground-nesting bird eggs.
The Graswarder Nature Reserve is a 230-hectare protected peninsula located between the Baltic Sea and the Heiligenhafen inner lagoon. It serves as a vital breeding and resting ground for numerous coastal bird species, including avocets, ringed plovers, and sandwich terns. The NABU center functions as an educational facility providing insights into the region’s unique salt marsh ecology and sand spit formation. A marked nature trail leads visitors through diverse habitats, including dunes, brackish meadows, and sandy beach sections. Access to the core protected zones is restricted to guided tours to minimize disturbance to local fauna. The area is defined by its dynamic coastal morphology, which continuously shifts due to currents and wind. It is one of the oldest nature reserves in Schleswig-Holstein, established for its ornithological significance.
The wooden observation platform overlooking the inner lagoon provides the best vantage point for capturing the landscape and local birdlife.
Bring high-quality binoculars, as most bird activity happens at a distance to prevent disturbing the wildlife.
Check the NABU center notice board for the daily schedule of guided interpretive walks.
Stay strictly on marked paths to avoid stepping on well-camouflaged ground nests during spring and early summer.
Attempting to walk through the restricted, fenced-off nesting zones or wandering into the private residential area at the peninsula entrance.
The nature trail may be temporarily restricted or partially closed during the peak breeding season (spring to early summer).
Keep dogs on a short leash at all times, remain on marked trails, and maintain a quiet volume to avoid spooking birds.
