Dilek Peninsula-Büyük Menderes Delta National Park , established on May 19, 1966, is a national park in western Turkey. It contains within its borders the entirety of the Dilek Peninsula as well as the large delta of the Büyük Menderes River. It is located in the Kusadasi district of Aydin Province, and as such it is also within the bounds of Turkey's Aegean Region. Directly west of the national park is the small coastal town of Güzelçamli, where several shuttle buses and ferries operate to and from the district's center of Kusadasi, approximately 30 km (19 mi) from the park.
