The Ilmenau originates in the Lüneburg Heath, south of Uelzen, as confluence of the rivers Gerdau and Stederau in, a district of Uelzen. It is a left tributary of the Elbe near Winsen.
The Ilmenau is long, including its source river Stederau. The largest towns along the Ilmenau are Uelzen and Lüneburg.
