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 Kuşadası district of Aydın 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 Güzelçamlı, where several shuttle buses  and ferries operate to and from the district's center of Kuşadası, approximately 30 km (19 mi) from the park.
