The five last-mentioned districts in the table constitute the folded limestone hilly region in the north, separated from the rest of the regency by the Brantas River. The rest of the regency to the south of the river is more low-lying and constitutes good agricultural land, although the south-east corner (Ngoro, Mojowarno, Bareng and Wonosalam Districts) is more mountainous.
