Dilek Peninsula National Park is located south of central Kusadasi, on the Aegean coast. It was established in 1966, and later the Buyuk Menderes River delta was included in the protected area. As a result, the park brings together not only a mountainous peninsula with forests and coves, but also one of the important wetlands of western Turkey.

The park covers an area of about 277 square kilometers. It is valued for its variety of natural conditions: there are slopes with pine and mixed forests, areas of Mediterranean scrub, rocky shores, beaches, and parts of the delta where birds stop and nest. This combination of landscapes makes the area appealing both for peaceful relaxation and for nature observation.

Wild boars, wildcats, and other mammals can be found in the park, while in the delta area you may see pelicans, herons, cormorants, and flamingos. The vegetation is typical of Turkey's western coast: pines, oaks, cypresses, junipers, ash trees, and oleanders. For tourists, the park is attractive for the opportunity to combine a nature trip with walks, swimming at the equipped beaches of the peninsula, and visits to scenic viewpoints.

Near the entrance is Zeus Cave, a well-known natural site with a cool pool. At the same time, part of the territory is under a strict conservation regime, so access to certain areas may be restricted. Before traveling, it is worth checking the current visiting rules, opening hours, and access conditions.
