The lake

Springs from the mountains feed the lake in winter; by summer the level drops and a strip of pale sand appears along the shore. The water changes colour from turquoise to deep green through the day. Its ancient name was Koresia, and locals once believed it had no bottom.

Wildlife

Look for freshwater turtles near the pedal-boat jetty, as well as herons, cormorants and ducks. Please do not feed the animals bread.
