In Ereğli, the rush of a major industrial city and the vacation mood of a long coastal stretch of beaches happen at once, and somehow you get used to it. Most evenings you'll drift from streets near the old castle down to the water, or just linger by the harbor. It's crowded, but calm in its own way. Not sure what to do? Pick a number — sea or city, Ereğli will take you there either way.
