Lake Stymphalia (Greek: Λίμνη Στυμφαλία - pron. "Límnē Stymphalía") is located in the north-eastern part of the Peloponnese, in the Corinthia prefecture. Other wildlife, such as weasels, can also be seen.
The area is also mentioned in Greek Mythology, due to the Stymphalian birds, which infested the Arcadian woods near the lake. Heracles' 6th labour was to exterminate them.
