Trelde Næs lies north of Fredericia, tucked between Vejle Fjord and the Little Belt, and quickly changes character along the way: forest, coastal meadow, coastline, bathing beach and steep cliffs are all close together. This makes the area suitable for both a short woodland walk and a longer trip around the headland.
Along the coast, it is especially the cliffs that give the place its character. On the southern side facing the Little Belt, the plastic clay can slide, causing entire sections of the cliff and trees to move down towards the beach. This is not only dramatic to watch; the landslides also expose new material, and fossils such as crabs, shark teeth and shark vertebrae can be found along the coast.
The Trelde forests are known for an unusually rich fungal flora, and Østerskov is home to many orchid species. Also look for the gnarled trees in Troldeskoven, where oak and beech grow among thickets of hawthorn, hazel, blackthorn, willow and blackberry, among other species. Several colonies of sand martins can be found in the cliffs, while the forest is home to birds of prey, tawny owls, ravens and green woodpeckers, among others.
