Limni Kourna (Kournas Lake) is one of two freshwater lakes in Crete, in the prefecture of Chania. It has an area of 160,000 square metres, which varies seasonally. Sheltered by surrounding hills, the lake has an idyllic setting that contains interesting flora and fauna.

The other is Limni Agias (Agia Lake) in Kydonia, also a wild life refuge, where many birds nest and wildflowers abound in spring. Agia Lake is in the middle of the fertile plain of Kydonia near the village of Agia.
