About The Place

Aroania, alternatively known as Helmos or Chelmos, is a prominent mountain range situated in the region of Achaea within the Peloponnese peninsula of Greece. Rising to an impressive elevation of 2,355 meters, Aroania claims the title of being the third highest mountain range in the entire Peloponnese, trailing only behind Taygetus and Kyllini, and proudly stands as the loftiest peak within the borders of Achaea. The nearby town of Kalavryta serves as the largest settlement in close proximity to this imposing mountain. It’s worth noting that the municipal unit Aroania derives its name from this very mountain, underscoring its significance in the local geography.

Aroania is strategically positioned in the southeastern reaches of Achaea, where it shares its border with Corinthia. To the east, at a distance of approximately 15 kilometers, lies the slightly taller Kyllini mountain, separated from Aroania by the picturesque valley through which the Olvios river meanders. On the western side, approximately 30 kilometers away, one encounters the mountain Erymanthos, which is situated across the valley carved by the Vouraikos river. Several rivers, including the Krios, Krathis, and Vouraikos, drain the waters from Aroania northward, ultimately pouring into the Gulf of Corinth. Conversely, the river Aroanios flows southwest, guiding its waters to the Ionian Sea.

Aroania is notable for hosting the prestigious Aristarchos telescope, a facility of astronomical significance, and is also home to a popular ski resort that attracts winter sports enthusiasts. The mountain offers a multitude of attractions, including the enchanting Cave of the Lakes (Spilaio ton Limnon), the serene monastery of Mega Spilaio, and the charming mountain town of Kalavryta. Scattered across the mountain’s slopes, you’ll discover quaint villages like Planitero and Peristera, each contributing to the unique character of this alpine landscape.
