Ørnbjerg Mølle is the only preserved functioning water mill in Djursland. It lies south of Feldballe, is surrounded by forest and gets water from Ulstrup River. It can be difficult to find, but cars are allowed through the forest to the mill.
The Mols route, which is a hiking route from Grenaa til Aarhus, passes by Ørnbjerg Mølle. If you follow the route marked going east, you will have a very nice walk along the river valley through a varying landscape. After around 3 km you get to Stubbe Lake, the largest lake in Djursland.
