The neighbouring countries of Maintal are Niederdorfelden and Schöneck in the north, the city of Hanau in the East, Mühlheim am Main and Offenbach am Main on the other bank of the river Main as well as Frankfurt am Main in the west.
The city was artificially created in 1974 in the course of the Hessian administration reform by merging the city of Dörnigheim (now Maintal's biggest district) with the nearby towns of Bischofsheim, Hochstadt and Wachenbuchen.
Maintal is connected with Hanau and Frankfurt by the so-called nordmainische Eisenbahn (northern Main railway) and has two stations (Maintal-West in Bischofsheim near the Main river and Maintal-East in Dörnigheim)
