Ørnbjerg Mill lies low by Ulstrup Å, east of Stubbe Sø, where forest, water and old working buildings still hold the mill environment together. The small whitewashed half-timbered building with a thatched roof is not just a backdrop: the mill functions as a museum mill, and on special occasions grain can still be ground here.
In the past, farmers came here to have their grain ground, and the wait could be long because milling was carried out on a first-come, first-served basis. That detail fits the place almost too well, where the calm today is part of the experience. In the picnic room, also called Svinehuset, there is an exhibition about the mill and the nature around it.
The area around the mill is part of Nationalpark Mols Bjerge and Ørnbjerg Naturperler. The landscape bears traces of the last ice age with hills, valleys and dead-ice holes, while the mill pond and the damp surroundings provide space for insects and small animals. The national park material mentions, among other species, moor frogs, adders and slowworms in the area, so good footwear and attention on the paths is not just practical common sense. From the mill, Stubbe Sø lies to the west, as a large, shallow lake in the hilly landscape.
