Heraea was favourably situated in several respects. Its territory was fertile, and it was situated on the high road from Olympia into the interior of Arcadia. From the north of Arcadia a road led into the valley of the Alpheius, near Heraea; and two roads led into the Heraeatis, one from Megalopolis, and the other from Messene and Phigalia, which joined the former close to the town. There was a bridge over the Alpheius close to Heraea, which Philip restored in 219 BCE. The Heraeatis was separated from Pisatis by the river Erymanthus, and from the territory of Megalopolis by the river Buphagus. The famous Tabula Peutingeriana shows a road system connecting Heraia with ancient Olympia, Melaneae and Megalopolis.
