The landscape is mainly deforested with flat or slightly undulating terrain, but in the north it turns into a hilly terrain. The territory extends into five geomorphological mesoregions: Jičín Uplands (most of the territory), Giant Mountains Foothills (northeast), East Elbe Table (south), Central Elbe Table (southwest) and Ještěd–Kozákov Ridge (small part in the north). The highest point of the district is the hill Kozinec in Vidochov with an elevation of 608 m (1,995 ft), the lowest point is the river bed of the Mrlina in Kopidlno at 206 m (676 ft).
From the total district area of 886.9 km2 (342.4 sq mi), agricultural land occupies 601.4 km2 (232.2 sq mi), forests occupy 193.3 km2 (74.6 sq mi), and water area occupies 14.1 km2 (5.4 sq mi). Forests cover 21.8% of the district's area.[1]
There are no significant rivers and bodies of water. The longest river is the Cidlina, which crosses the territory from north to south. Another notable rivers in the district are the Mrlina and Bystřice. The largest body of water is the pond Zrcadlo with an area of 60 ha (150 acres).[3]
