The Dill flows exclusively through the Lahn-Dill-Kreis district in Hesse. The river originates at about 567 m above sea-level north of Haiger-Offdilln on the eastern slope of the Haincher Höhe (heights that reach 606 m), where the mountain ranges Rothaargebirge and Westerwald meet. During its course, roughly from north to south, the Dill passes the towns of Haiger, Dillenburg, Herborn, Aßlar, and finally empties into the Lahn at Wetzlar.
Many places on the banks of the river draw their names from it. On the river's upper reaches these are Offdilln, Dillbrecht, Fellerdilln, Dillenburg, and further downstream Dillheim. Dillenburg was the seat of the former Dillkreis district and residence town of the House of Orange-Nassau.
Going downstream, the Dill's largest tributaries are: Roßbach, Haigerbach, Aubach, Donsbach, Dietzhölze, Nanzenbach, Schelde, Aar, Ambach, Rehbach, Lemp, and Blasbach.
