Crete's only freshwater lake, Lake Kournás (GR: Λίμνη Κουρνά), is relatively large, with a perimeter of 3.5 km. Although almost all touristic leaflets say that it is possible to walk around the lake, that is not true. At least not at the end of the rain season (winter). There is a nature preserve on the Southwest of the lake. But there is a rustic road from the North of the lake to the Hills on the West of the lake too.
The lake used to be called 'Korisía' after ancient 'Korion', a city thought to be in the area with a temple to Athena. The lake reportedly used to be full of eels but now is better known for its terrapins and tourism. Tavernas and pedalo rental shops line part of the shore. Overall, however, the lake retains its beauty, the White Mountains reflected in the mirror-like waters.
