Aroania is situated in southeastern Achaea, near the border with Corinthia. The slightly higher Kyllini mountain is about 15 km to its east, separated from Aroania by the valley of the river Olvios. The mountain Erymanthos is about 30 km to the west, across the valley of the river Vouraikos. The rivers Krios, Krathis and Vouraikos drain the mountain towards the Gulf of Corinth in the north. The river Aroanios drains the mountain towards the southwest, to the Ionian Sea.
The mountain is the site of the Aristarchos telescope and of a ski resort. Points of interest on the mountain include the Cave of the Lakes (Spilaio ton Limnon), the monastery of Mega Spilaio and the mountain town Kalavryta. Mountain villages on the mountain are Planitero and Peristera. There are several protected areas on Aroania.
