Near the village of Parzeńsko, close to Nowogródek Pomorski, you can see the spring of the Kłodawka river. As it flows through these lands, it fills up numerous fishing ponds, and its downstream section flows through Gorzów Wielkopolski and into the Warta. There is a grove with a waterfall at the ruins of the old Prostki water mill. The waterfall is fed by one of the streams springing from the marshes and swamps of Trzciniec.
