It flows through the Polish Jura, after which it enters Central Polish Plains. Pilica flows into the Vistula near the village of Ostrowek, in a geographical region of Central Vistula Valley. In 1974, a dam was built near Sulejow, resulting in the creation of man-made reservoir Sulejow Lake, which has the area of 2,700 hectares. The region in the basin of the Pilica is sometimes called Nadpilicze, and the river itself marks boundary between Lesser Poland, and two other historical provinces of the country, Greater Poland and Mazovia.

The first "open-air river museum" in Poland, the Open-air museum of Pilica river, is located on the waterway and the Blue Springs nature reserve lies next to the river.
