Česká Lípa District briefly borders Germany in the north. 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). The highest point of the district is the mountain Luž in Mařenice with an elevation of 793 m (2,602 ft), the lowest point is the river bed of the Liběchovka Stream in Dubá at 222 m (728 ft).
From the total district area of 1,072.9 km2 (414.2 sq mi), agricultural land occupies 430.8 km2 (166.3 sq mi), forests occupy 506.6 km2 (195.6 sq mi), and water area occupies 25.8 km2 (10.0 sq mi). Forests cover 47.2% of the district's area.[1]
The most significant river is the Ploučnice, which flows across the district from east to west. Its longest tributary in the district is the Svitavka. The largest body of water is Lake Mácha.
There are no motorways in the district territory. 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.
