The Kniepsand, located adjacent to the dunes, is not technically an island-based dune but a massive wandering sandbank that has gradually attached itself to the west coast of Amrum.
The shifting sand patterns mean the dunes are in a constant state of morphological change, often burying older vegetation while revealing new topographical forms.
The dunes host specific flora such as the sea buckthorn and salt-tolerant grasses that are critical for stabilizing the sandy terrain.
The AOK-Dünen section is named after a former children's sanatorium that once occupied the site, taking advantage of the high-aerosol maritime air.
The Amrumer Dünen are a sprawling, protected dune belt on the island of Amrum that separates the island's western sandy beach, the Kniepsand, from the residential interior. Spanning approximately 12 kilometers in length, the dunes reach heights of up to 32 meters at the AOK-Dünen. The area is characterized by shifting sands, marram grass, and unique scrub vegetation adapted to salt spray and high winds. Extensive wooden boardwalks cross the landscape, protecting the fragile ecosystem from foot traffic erosion. The dunes act as a natural coastal defense barrier for the island, preventing storm surges from reaching the villages. Many sections are designated as nature reserves where human activity is strictly limited to marked paths.

Stay strictly on the designated wooden boardwalks to avoid damaging the sensitive dune vegetation and risking fines.
Wear wind-resistant clothing as the exposed nature of the dunes makes them significantly windier than the inland forest areas.
Bring binoculars, as the dune landscape provides excellent visibility for birdwatching during migration periods.
Walking through unmarked areas, which damages the dune structure and is prohibited by environmental regulations.
Stay on marked paths at all times; do not pick flowers or vegetation; dogs must be kept on a leash to protect ground-nesting birds.
