Why Natura 2000 Area No. 51 Begtrup Vig and Coastal Areas at Helgenæs stands out
The area is best known for hosting some of the largest connected stretches of coastal dry grassland in Denmark, particularly the sandy and calcareous coastal slopes between Sletterhage on the southern tip of Helgenæs and the northeast of the peninsula. These open grasslands, set against the backdrop of the Kattegat, sit alongside impressive recurved spit systems and raised seabed formations that document the slow rise of the Danish landscape since the last ice age. Equally central to the site's identity is the combination of cliff, dune, and marine shallow-water habitats along Begtrup Vig. The contrast between the steep coastal cliffs on the west side of Helgenæs and the flat, heath-clad marine foreland on the east side gives the site a strong sense of physical and ecological variety, while the narrow land connection to Mols adds a distinctive geographic framing.

The physical landscape of the site is shaped almost entirely by the interaction of glacial inheritance, land uplift, and ongoing marine processes. Helgenæs itself represents a peninsula carved out of the broader Mols moraine landscape, with its axis bending southward toward the Kattegat. About three quarters of the protected area is marine, covering Begtrup Vig and surrounding shallow waters out to a depth of ten meters, where light penetration allows submerged sandbanks, lagoons, and reefs to develop.
On land, the western coast of Helgenæs rises into steep coastal cliffs between Fejrup and Ørby, exposing geological sequences tied to the Pleistocene history of eastern Jutland. Below these cliffs, narrow boulder and shingle formations meet the sea, often lined by rows of beach ridges that mark former shorelines. In the north, the coast near Strands and at Stavsøre shows extensive raised seabed with curving recurved spit systems, where former seabeds have been lifted into dry land and shaped into large coastal arcs.
The eastern side of the peninsula tells a quieter morphological story. Here, the older Stone Age sea cliff forms a backdrop to a flatter marine foreland where wind, grazing, and time have produced dry heath and grassland mosaics. South of Sletterhage, sandy slopes open into broad coastal dry grasslands that extend toward the lighthouse area, forming some of the largest connected grassland surfaces in Denmark. The narrow land bridge of Draget between Helgenæs and the Mols mainland adds a final defining element to the landscape, with shallow marine waters and tidal flats on either side.
Natura 2000 Area No. 51 Begtrup Vig and Coastal Areas at Helgenæs ecosystems, habitats, and plant life
Ecologically, the area is defined by an unusually rich meeting zone between marine, littoral, and terrestrial habitats. The marine side includes sandbanks, coastal lagoons, bays, and reefs supporting diverse submerged and semi-submerged communities, while the shoreline transitions into beach-ridge formations, shifting dunes, dune heath, grey and green dune vegetation, and dry heath further inland.
The grasslands of south and east Helgenæs are particularly significant at the national scale. Dry calcareous grassland and dry calcareous sand grassland are present alongside more acidic dry grassland communities, while inland the habitat network also includes nutrient-rich lakes, flushed springs, and rich fen vegetation. These habitats support specialized flora adapted to the dry, sun-exposed coastal environment, and they form the backdrop for the area's strong invertebrate and bird populations.
Wetland habitats are present in lower but ecologically important amounts, including freshwater meadows, raised bog patches, and coastal meadows along the bay edges. Together with mires and source springs around the cliffs, these humid pockets add microhabitat diversity to an otherwise open coastal landscape. Roughly 295 hectares of land habitats across the site are protected under Section 3 of the Danish Nature Protection Act, which underlines the integrated mosaic approach to habitat conservation here.

Although the area is primarily described through its habitats rather than its fauna, the mosaic landscape supports several characteristic coastal species groups. The freshwater and wetland components, including ponds and springs, provide suitable breeding habitat for the great crested newt, which is the species explicitly listed in the site designation. Coastal meadows and reed belts around Begtrup Vig also offer feeding and resting areas for waterbirds and waders.
The dry coastal grasslands and heath zones around Sletterhage and eastern Helgenæs are typically rich in insects, including butterflies and other pollinators that depend on the open, sun-exposed structure of these habitats. Gulls, seabirds, and migrating waterbirds make regular use of the marine shallows and bay edges, while the varied cliff and beach-ridge landscape creates nesting and shelter opportunities for several coastal bird species across the seasons.
Natura 2000 Area No. 51 Begtrup Vig and Coastal Areas at Helgenæs conservation status and protection priorities
Conservation significance here is rooted in the size and connectivity of habitat patches that are rare at the Danish national level. The site contains priority habitat types including coastal dunes, calcareous grasslands, calcareous sand grasslands, acidic dry grasslands, and source-spring communities, marking it as a national-level stronghold for these ecosystems. The combination of marine, coastal, and inland calcareous habitats in a single designation creates a conservation area that responds to changes in sea level, land use, and grazing management in an integrated way.
The Natura 2000 plan adopted in 2011 and continued in later planning cycles has structured ongoing management through binding action plans prepared by the municipality and the Danish Nature Agency. The site is also coordinated with the relevant water plan for Aarhus Bay, recognizing the strong hydrological coupling between Begtrup Vig and the surrounding land. The northern part of the designation overlaps with Nationalpark Mols Bjerge, expanding the conservation context from a strictly habitat-area setting into a broader landscape-scale approach.
Top sights and standout views in Natura 2000 Area No. 51 Begtrup Vig and Coastal Areas at Helgenæs
The site's strongest distinguishing features include the large, nationally significant coastal dry grasslands around Sletterhage, the dramatic cliff coast between Fejrup and Ørby on western Helgenæs, and the extensive raised seabed and recurved spit systems around Strands and Stavsøre. The marine belt of Begtrup Vig adds shallow sandbanks, lagoons, and reefs that anchor the area ecologically.
Cultural-geographic features also play a role, particularly the narrow land bridge of Draget between Helgenæs and Mols with its protected historic earthwork Dragsmur, and the Ørby Klint area, where a long stretch of cliff coastline is under formal protection. The connection to Nationalpark Mols Bjerge in the northern portion of the area adds an additional layer of landscape-level recognition.
