Agger Tange

Furthest south of Thy National Park lies the Agger Tange isthmus, surrounded by dykes and protected against the North Sea by breakwaters. From the sea wall and the inlet embankment there is a full view of the sea, the Limfjord and the beautiful moraine landscapes to the north and the east. 

Rich birdlife

The open landscape is an Eldorado for many birds, not least during spring and autumn when thousands of web-footed birds and wading birds rest on their way to breeding grounds and winter quarters. There is rich birdlife on the isthmus because the area is located on the birds' migratory route along the west coast of Jutland, and it is not without reason that Agger Tange has been appointed as an EU Bird Protection Area.

Flocks of mallard, Eurasian teal and wigeon - and in the autumn also common pochard and common goldeneye - take up residence in the shallow lagoons. Moreover, flocks of mute swan reside here, and during the winter also Beckwick's swan and whooper swan. Pink-footed geese and brent geese can be seen in spring as well as autumn. Wading birds also use the salt meadows and the flat coasts of the lagoons. Here you can see flocks of golden plover, lapwing, oystercatcher, dunlin, Erusian curlew and whimbrel as well as common snipe. During the breeding season the number of birds decreases, but you can still see some of the web-footed birds and wading birds that breed in the area, for example mute swan, mallard, shelduck, pintail and coot. You can also see dunlin, oystercatcher, avocet, redshank, ruff and black-tailed godwit, as well as colonies of gulls and terns.

The purpose of the conservation of Agger and Harboøre isthmuses is to improve conditions for the birds. The area is managed by the Danish Nature Agency and this work primarily includes grazing the salt meadows to prevent them from becoming overgrown with reed, willow and buckthorn.

The cattle used to graze the isthmus develop good quality meat which you can buy from the local butcher in Vorupør.

The southern point of Agger Tange is a good place to see the common seal. The seals take up residence on the sand banks and reefs in the Limfjord. From the ferry to Tyborøn, you can also see groups of seals resting with flocks of cormorants on the sand banks east of the ferry route.

Visit the isthmus and the information house

The national park's information house, which was built at the ferry dock in 2012, introduces the entire national park with special emphasis on the nature on Agger Tange. From the roof of the building you can watch birds and seals. From a number of lay-byes along the ferry road and from the bird watching post on Arbejdsvejen south of Agger, you can study the birdlife in the lagoon. These places also offer a golden opportunity in September at sunset when thousands of greylag geese fly in from east to spend the night in the lagoon.

Access rules: Passage on the water bodies of the isthmus is prohibited all year round. Passage on the low-lying meadows and wetlands is prohibited in the birds' breeding season from 1 April to 15 July.
