The Flechtingen Hills are bordered by the River Aller to the west, the Spetze, a right-hand tributary of the Aller, to the north, the valley of the Ohre to the northeast, through which the Mittelland Canal also runs, and by the Beber, a tributary of the Ohre, to the south.

One of the highest elevations in the Flechtingen Hills is the Butterberg near Ivenrode at 176 m above sea level (NN).

Unlike the surrounding region, geologically old rocks reach the surface of the Flechtingen Hills.

Regionally the ridge is part of the Flechtingen-Roßlau Scholle, that runs in the northwest from the depression of the Drömling towards the southeast to Magdeburg and the river Roßlau.

Another well-known ridge in this Scholle is the Magdeburg Domfelsen, which acts as a sill to the Elbe and markedly raises its water velocity.
