Beysehir lake is the third largest lake in Turkey, and as a result of chemical reactions it has formed many islands, which are the remains of cavernous geological structures. The lake was accepted as a first grade natural site area in 1991. Lake Beysehir ,which has the largest freshwater reserves of Turkey,has a rich biological diversity both in the water and in the islands and coasts. The islands provide a home for thousands of water birds which nest there, including swans, cormorants, ducks and divers. Species of trees here include juniper, blackpine, firs, cedar and oak. In addition to the natural beauty of the area, it also has an interesting history as it was governed by Hittites, Friesian, Lydias, Persians and Byzantines. Finally, the Anatolian Seljuks conquered the area, and since then it has been under the reign of the Turks. Beysehir is 90 km from Konya.
