Most of the territory is flat and has an agricultural character, only the south and northeast are hilly. The territory is located in the rain shadow of the Ore Mountains and therefore belongs to the driest regions of the country. The territory extends into five geomorphological mesoregions: Most Basin (north and centre), Rakovník Uplands (southwest), Džbán (south), Lower Ohře Table (east) and Central Bohemian Uplands (northeast). The highest point of the district is a contour line on the slopes of Ostrý hill in Libčeves with an elevation of 609 m (1,998 ft), the highest peak is Velký les in Blatno with an elevation of 592 m (1,942 ft). The lowest point is the river bed of the Ohře in Koštice at 165 m (541 ft).
From the total district area of 1,121.0 km2 (432.8 sq mi), agricultural land occupies 788.4 km2 (304.4 sq mi), forests occupy 180.5 km2 (69.7 sq mi), and water area occupies 15.6 km2 (6.0 sq mi). Forests cover 16.1% of the district's area.[1]
The most important river is the Ohře, which drains almost the entire territory. Its most important tributaries are the Blšanka and Chomutovka. The largest body of water is Lenešický Pond. However, there are only a few bodies of water.
The D7 motorway from Prague to Chomutov, including the unfinished section, leads across the district. The D6 motorway from Prague to Karlovy Vary passes through the southern part of the district.
