Erdek is Balikesir's district on the Marmara coast. With fine sandy beaches, clear water, and clean air from the Kaz Mountains, it has long been a favorite family holiday destination. The town center and surrounding villages — including Turankoy, Narli, and Zeytinli — form a wide accommodation network.

Erdek Bay offers shallow, calm water ideal for families with children. Islands in the bay — especially Pasalimani — host day-trip boat tours. The district has local markets, fish restaurants, and coastal walking routes.

Erdek is reachable by road from Istanbul and Bursa in a few hours. Ferry connections via Bandirma and bus links make travel practical. Turankoy's proximity to Erdek center makes it an ideal base for exploring the region.
