Ještěd–Kozákov Ridge

The average altitude is 518.5 m.[2] In the northwest it starts with the hill Ostrý vrch (511 m).

The elevation of the hills gradually increases above 800 metres and culminates with Ještěd.

The largest settlements whose territories extend into the ridge are Liberec, Semily, Chrastava and Lomnice nad Popelkou.

The central part of the ridge (including the Kozákov mountain) intersects the Bohemian Paradise Protected Landscape Area.

In addition to several small-scale protected areas, the Ještěd and Maloskalsko nature parks have been created.
