Isparta
Lake Eğirdir is in Isparta province, in the Lakes Region of southwestern Anatolia. It is the second-largest freshwater lake in Türkiye. The town of Eğirdir stands on a peninsula at its southern end, about 35 km from the city of Isparta.
Eğirdir Castle stands on the peninsula; its surviving walls date from the Byzantine period. In the town, the Dündar Bey Madrasa was built as a han in 1237. Dündar Bey of the Hamidoğulları turned it into a madrasa in 1301. A short causeway leads to Yeşilada (Green Island), formerly called Nis. Greek families lived there until 1923. Today wooden houses on stone bases, guesthouses and fish restaurants fill the island.
The walk from the castle across the causeway to Yeşilada is short and level. Altınkum Beach lies just outside the centre. Restaurants in town and on the island serve fish from the lake, such as carp.
