Ambodimanga is situated at the Ramena River, at its outlet to the Sambirano River. The valley of the Sambirano is the main cocoa producing area of Madagascar. 60% or 7500 to 10 000 ton yearly provide from this area. There is an unpaved piste from Ambanja to Marovato, via Benavony, Ambodimanga Ramena, Bemaneviky Ouest, Maevatanana that is hardly practicable. Most of the exported cocoa is therefore transported with boats on the Sambirano River.
