The Aroanios (Greek: Αροάνιος; Ancient Greek: Ἀροάνιος; Latin: Aroanius) is a river in the southern part of Achaea, Greece and a tributary of Ladon river. The water comes from the carbonate mountain range Aroania (1500-2300m). After 12 km, it meets the Ladonas (near to Pangrataika Kalyvia) in the area of "Helongospilia” (Χελωνοσπηλιά).[1]
