The Jizera Foothills is a mesoregion of the Western Sudetes within the Bohemian Massif. The mesoregion is a foothill area of the Jizera Mountains and extends north of the mountain range. The relief is slightly undulating with low but prominent hills.
The highest peaks of the Jizera Foothills are: Andělský vrch, Hřebenáč, Sroczka,
Geology The bedrock is mainly composed of gneisses and biotite granites, supplemented by Neogene basalts and phonolites. There are also Quaternary sedimentary rocks here, which are a remnant of the Pleistocene glaciation.
