The sub-prefectures of the department are Bédy-Goazon, Guiglo, Kaadé, and Nizahon.

Using current boundaries as a reference, from 1969 to 1988 the department occupied the same territory as Cavally Region plus Duékoué Department of Guémon Region.

[6] In 2011, districts were introduced as new first-level subdivisions of Ivory Coast.

At this time, Guiglo Department became part of Cavally Region in Montagnes District.
