Stymfalia is a swampy lake in mountainous Corinth. It is located on a plateau at an altitude of 600 meters between the mountains Kyllini and Oligyrtos. It retains water mainly during the winter months and its area reaches 3.5 sq.km. The depth of the Lake in the places where it is permanently covered by water ranges from 2 / 2.5 meters in the Spring and about half (0.5) meter in the beginning of Autumn.Lake Stymfalia is associated with the sixth feat of Hercules who in the area faced the Stymfalides Hens. Hercules managed to lure the hens out of the dense vegetation of the lake, thanks to the copper rattlesnakes given to him by the goddess Athena. Then Hercules succeeded the hens that were revealed with his arrows.
