Corinthia borders on
Achaea to the west and southwest, the
Gulf of Corinth and
Attica to the north, the
Saronic Gulf to the east,
Argolis to the south and
Arcadia to the southwest. The
Corinth Canal, carrying ship traffic between the
Ionian and the
Aegean seas, is about east of
Corinth, cutting through the
Isthmus of Corinth. Corinthia is increasingly seen as part of the wider metropolitan area of
Athens, with municipalities, such as
Agioi Theodoroi in the easternmost part of the regional unit, being considered suburbs of Athens. The area around Corinth and the western
Saronic including the southeastern part are made up of fault lines including the
Corinth Fault, the
Poseidon Fault and a fault running from Perahcora to Agioi Theodoroi. More faults are near
Kiras Vrysi and Sofiko. The eastern coastlands of Corinthia are made up of pastures and farmlands where olives, grapes, tomatoes and vegetables are cultivated. The rest of Corinthia is mountainous. Its tallest mountain is
Kyllini in its west and the largest lake is
Lake Stymphalos, (important in Greek mythology and a bird resort, protected by
Natura 2000) situated in the southwest. The reservoir will become one of the largest lakes after its completion. The climate of Corinthia consists of hot summers and mild winters in the coastal areas and somewhat colder winters with occasional snowfalls in the mountainous areas. ==Administration==
