The subject of protection is the valleys of the Warta, Widawka and their tributaries together with the surroundings, as well as the natural vegetation accompanying these areas.

In the central part of the park, there is an interesting hydrographic junction formed by the converging rivers: Widawka, Grabia and Nieciecz.

The area of the park is distinguished in its surroundings by a varied topography, especially the picturesque gorges of the Warta River, where the relative heights of the slopes reach 45 meters (between Beleń and Strońsko), and old limestone formations appear on the surface.

From the high shores, you can observe the vast panoramas of the valley, meandering sections of rivers, oxbow lakes, dune areas, peat bogs, wetlands with an abundance of marsh plants.
