The ridge, which runs from northwest to southeast at heights between 400 and 700 metres, is a fold mountain range consisting of limestone, slate and dolomite. In the west the Bober separates the range from the Jizera Mountains and Jizera Foreland; to the north are the Katzbach Foothills; to the east the Raging Neisse / Nysa Szalona forms the boundary. In the southeast, the Katzbach Mountains merge into the Waldenburg/Walbrzyskie Highlands. To the south, the Landeshut Ridge / Rudawy Janowickie and Jelenia Gora Valley form the transition to the Giant Mountains.
