The relief is rugged, constituted mostly of hilly units belonging to Someș Plateau and, to a lesser extent, of mountain portions that represent the northeastern part of Apuseni Mountains.
Fields are missing on the territory of Cluj County, being replaced, as step of relief, by well developed terraces and floodplains in the lower sectors of Someșul Mic and Arieș rivers.
The hilly area, extended in the central northern and southern part of the county, include several subunits of Someș Plateau (Cluj, Feleacu, Dej hills), among which are individualized numerous depressions (Apahida, Bonțida, Gilău, Dej, Turda, Câmpia Turzii) at the edge of which there are some contact depressions (Huedin and Iara), at the limit of the mountain.
The mountain sector, located in southwest, belongs to Apuseni, mountains group of Western Carpathians, represented by sectors of Vlădeasa Massif (peak Vlădeasa – 1,836 m), Gilău Mountains and Muntele Mare, as well as narrow portions of Trascău, Plopiș, Meseș and Bihor mountains.
In the eastern part of Cluj County, east of the river alignment Valea Florilor–Maraloiu–Someșul Mic, is located a part of the Hilly Plain of Transylvania, special unit of relief, with mountainous character, partially overlapped by some gas-condensate domes.
