High on the right bank of the Vistula River there are limestone hills, the afforestation of which began in the interwar years. Beautiful walking paths and grottoes add charm to the park. According to legend, Master Twardowski had his sorcerer’s laboratory in one of the caves here. There are other green enclaves in the city, however small in terms of area. Those are: park in Prokocim, Mirowski Park in Prądnik, Kleparski Park and Wyspiański Park
