In the northwestern Peloponnese, between the county of Achaea and Ilia is the mount Erymanthos.

Erymanthos is the fourth in height mountain of the Peloponnese and is among the alpine mountains of Greece. Its highest peak is Olenos with altitude 2224 meters that is located in the region of Achaea, almost bordering with Ilia. Other peaks are Mougila (2169 meters), the Prophet Elias (2125 meters), the Pyrgakos (2050 meters), the Neraidovouni (the mountain of the fairies)(1923 meters), the Psili Tourla (1891 meters) and the Lepida (Blade) (1541 meters). From Mount Erymanthos several rivers derive such as Penaeus, the Selinountas, Erymanthos and others.

Erymanthos mountain is characterized by the wild natural surroundings and the dense vegetation with about a thousand different species of plants. The slopes of the 800 m and above are filled with forests reaching in some cases up to 1700 meters, but from then on the mountain is bare, thus creating a spectacular natural contrast.

According to mythology it was here that the famous hero Hercules made one of his labors by killing the Erymanthio Boar. If you are into hiking, mountaineering and climbing in a beautiful setting, you have to pass by Mount Erymanthos.
