The rocks, with their cracks and small caves in the calcareous wall, provide an important nesting site for numerous bird species such as jackdaws, house martins, fulmars, kestrels, gulls, terns and herring gulls. As part of a renaturation project in 2006, a section of the asphalt road leading to the summit and the parking spaces there were completely removed. Instead, a parking lot about 300 meters inland was significantly expanded.

Incredibly beautiful paths - partly on wooden planks, partly through fine sand. A small, hidden natural paradise that can be wonderfully explored on a circular hike.
