Mount Erymanthos (Greek: Ερύμανθος, Latin: Erymanthus) overall is an irregular massif of peaks connected by ridges embedded in the mountains located in the north of the Peloponnese, Greece. Erymanthos is on the west side. Its highest peak, Olenos or Olonos (Ωλενός or Ωλονός), Olenos original and preferred, elevation 2,224 m (7,297 ft), is often called Mount Erymanthus, and conversely, Mount Olenos can be used for the entire range, although the customary usage is Erymanthos for the range and Olenos for the peak.
