Mount Aenos or Ainos is the tallest mountain in the island of Kephalonia, Greece. Its bedrock is dominantly dolomite and limestone of Cretaceous age.
Most of the mountain range is designated as a National Park area and is covered with Greek fir (Abies Cephalonica) and black pine (Pinus nigra). Pine forests are found between the elevations of 700 to 1200 m. Semi wild ponies inhabit its forest.
On clear days, the view includes the NW Peloponnese and Aetolia along with the islands of Zakynthos, Lefkada, and Ithaca.
No ski resorts are found on this mountain range, but there are beautiful caves to be seen in the north. A highway passes over the mountain range connecting traffic from southwestern to the eastern part of the island is one of the few roads going into the mountain range.
