The terrain is very diverse, with large differences in altitude, and hilly landscape prevails.

The territory extends into four geomorphological mesoregions: Ralsko Uplands (most of the territory), Central Bohemian Uplands (west), Lusatian Mountains (north) and Jizera Table (small part in the southeast).

There are three protected landscape areas: Lusatian Mountains, Central Bohemian Uplands and Kokořínsko – Máchův kraj.

The most important roads that pass through the district are the I/13 (part of the European route E442) from Liberec to Karlovy Vary, and the I/9 from Prague to the Czech-German border via Česká Lípa.
