The Kielce-Sandomierska Upland in its central part turns into an old rock mass - the Świętokrzyskie Mountains. The highest range is Łysogóry (with the peak of Łysica 612 m), to which the primeval landscape is created by the gravel area, that is, the debris of hard quartzites. The peak parts of the ridge are covered by the Jodłowa Primeval Forest, which is part of the Świętokrzyski National Park. The Lublin Upland is part of the great Black Sea plate. It is made of chalk tracks, has a varied sculpture. The deep valleys of the Wieprz and Bug rivers are characterized by specific beauty. The highlands include Roztocze - a narrow upland belt, in some places having the character of a mountain landscape.
