The city of Mojokerto, which since 1999 has been administratively independent of the Regency (although the regency administration remains at present centred on the city), virtually divides the regency into two zones - the southern zone comprising the first 14 districts listed above, and the smaller northern zone, comprising the last 4 districts listed above.
Mojokerto Regency’s area is 872 km², located between 15 m and 3,156 m above sea level. It is divided into northern and southern regions by the Brantas River. The southern region has several mountains, which includes Welirang Mountain (3,156 m), Anjasmoro Mountain (2,277 m) and Penanggungan Mountain (1693m).
One of the several beautiful locations in Mojokerto is Pacet; it has a magnificent mountainous view.
