Geding-Kasted Mose is a bog about 7 kilometers north-west of Aarhus, in the western section of the Egå river valley though which the river Egå runs. The bog covers about 30 hectares of which a sizable portion is used as meadows for grazing cattle. Other parts are cultivated but as the area is low-lying it is more or less flooded during winter. The bog has some waterholes and old peat pits which are now mostly concealed by thickets of primarily downy birch and grey willow.

Geding-Kasted Bog is one of the most important catchment areas for the water supply in Aarhus Municipality and the city of Aarhus.

Geding-Kasted Bog has a major biodiversity with many different plant and animal species. Especially downy birch and grey willow dominate but on the meadows there is also globeflower, branched bur-reed, western marsh orchid, saw-wort and Irish fleabane. Insects are important pollinators for the flowers in bog and as prey for toads, reptiles and birds. Due to the location between the nesting grounds Egå Engsø and Brabrand Lake there's an especially varied population of birds including thrush nightingale eurasian penduline tit, water rail, western marsh harrier, common kestrel and grey heron.

The bog was used for grazing cattle for many years which was maintained by a local group of volunteers. In the 2010s the bog will undergo a rewilding project that will introduce Galloway cattle and later possibly water buffalo and wild horses.
