Zonguldak is a Black Sea province in northwestern Turkey celebrated for its rich coal-mining heritage, dramatic coastal scenery, and lush forested hills. Carved out of Carboniferous rock over millennia, the region boasts the Gökgöl Cave — one of Turkey's largest and most spectacular stalactite caves — along with ancient ruins at Filyos (ancient Tios) and rugged Black Sea beaches. The provincial capital sits on a steep peninsula jutting into the Black Sea, giving it a distinctive character quite unlike Turkey's sun-belt resorts.
