The terrain in the central lowlands is flat, cut by several major rivers, including the Odra (Oder), which defines the Silesian Lowlands in the southwest, and the Wisla (Vistula), which defines the lowland areas of east-central Poland.
To the south are the lesser Poland uplands, formed by the gently sloping foothills of the Sudeten and Carpathian mountain ranges and the uplands that connect the ranges in southcentral Poland.
The third topographic area is formed by the Sudeten and Carpathian ranges. Within Poland, these ranges hold substantial human habitation, the Carpathians being densely populated. The rugged form of the Sudeten range derives from the geological shifts that formed the later Carpathian uplift. The highest elevation is in the Sudeten at 1,602 meters, in the Karkonosze Mountains.
The Carpathians in Poland are the highest and most picturesque mountains in the country. They are the northernmost edge of a much larger range that extends into the Czech Republic, Slovakia, Ukraine, Hungary, and Romania. In Poland the range includes two major basins, the Oswiecim (Auschwitz) and Sandomierzs. -text edited from Wikipedia.
Mount Rysy 2499m (8119 ft) in the Tatra Mountains, near the Slovak border, is the highest peak in Poland.
