The Mangoro begins northeast of the town of Anjozorobe in the Analamanga region, at approximately 1,100 meters. Its primary tributaries are the Onive River (which joins on the right bank at 200 km from the river source) and Nosivolo River.[3][1] Its mouth is at the Indian Ocean near the town of Ambodiharina.

Owing to its many tributaries, the Mangoro maintains a high flow year round, making it an ideal river for rafting.[4]

As of 2012, the Sherritt International Corporation planned to use the Mangoro River as a source of water for a slurry pipeline carrying ore for the Ambatovy project mines, raising environmental concerns.<ref>"Another Mining Horror Story?

There are small populations of crocodiles in the more placid sections of the river, but their population is minimal and continues to plummet.[4]
