The Hörfeld Moor lies south of Mühlen on the border between Styria and Carinthia in a depression that was carved out by the ice age glaciers. Since then, a moor with adjacent wet meadows has developed. Because of its importance for nature, it was declared a European protected area.
This means that you can discover such pretty moor plants as the white-flowered marsh trefoil, the pond horsetail, the yellow-flowered marsh marigold and the yellow-flowered tongue buttercup. Shrubs and trees, such as the buckthorn and the downy birch, are often mixed in.
The small lakes provide the common frog, yellow-bellied toad and common toad with their spawning waters. The flower-rich tall shrubs provide a habitat for numerous, colorful butterflies, including the large meadow brown, which is endangered throughout Austria, and the fritillary. The Valerian fritillary is particularly pretty with its orange-black mottled wings. There are also over 130 species of birds to observe: Whinchat, Common Rosefinch, Lapwing, Corncrake, Teal and Water Rail are some of them.
The starting point is the car park on the B92 south of Mühlen. To the southwest, the path leads directly into the moorland.
