Sokolov District borders Germany in the north. The terrain is characterized by two mountain ranges with a forested landscape, between which there is an unforested depression. The territory extends into five geomorphological mesoregions: Ore Mountains (north), Sokolov Basin (centre), Slavkov Forest (south), Cheb Basin (small part in the west) and Fichtel Mountains (very small part in the northwest). The highest point of the district is the mountain Špičák in Stříbrná with an elevation of 995 m (3,264 ft). The lowest point is the river bed of the Ohře in Loket at 374 m (1,227 ft).
From the total district area of 753.7 km2 (291.0 sq mi), agricultural land occupies 209.0 km2 (80.7 sq mi), forests occupy 390.1 km2 (150.6 sq mi), and water area occupies 17.4 km2 (6.7 sq mi). Forests cover 51.8% of the district's area.[1]
The most important river is the Ohře, which flows across the district from west to east and drains the entire territory. Its longest tributary in the district is the Svatava. The Teplá River forms part of the southeastern district border. There are several water reservoirs and artificial lakes created by reclamation after coal mining. The largest body of water is Medard Lake.
