The Zittauer Gebirge, also called the upper Lusatian, are a part of the Sudeten which extends through areas of Germany, Czech Republic and Poland. The Sudeten divides itself into several branches and stretches in the northwest southeast directions to the valley of the river Elbe to the mährischen gate. The highest elevation is the Schneekoppe in the Sudeten Mountains at 1.602 m.
Isergebirge forms the connection between the Sudeten Mountains and the Zittauer mountains. The highest mountain, the Iser (1.127 m) gives its name to the mountains. The Lausche (793 m) and the Hochwald(750 m) are the highest mountains in the Zittauer range. These make up a large part of the mountains of volcanic origin.
