Lake Tsivlou lies at an altitude of 700 m. and it's one of the very few mountainous lakes in the Peloponnese.
It was formed by a landslide in 1912 which blocked Krathis river.
Today the lake's maximum depth is approximately 30 m. and it's a spot of attraction for tourists and naturalists.
Tsivlou lake hosts rich flora and fauna and it is ideal for birdwatching.
