The source of the Aroanios river lies in a forest of plane trees close to the village of Planitero. It comprises waters from the Feneou basin which rise from sink holes joined by streams in the Langada and Haliki valleys and they flow Southward for some 10 km until they join the Ladon river.

A visitor can enjoy the beauty of the plane trees and the food in the taverns of the village .

Small nearby shops sell aromatic honey and walnuts.

Fish farms in the area breed perch and salmon.
