Sinop
Castle, prison and fjord at Türkiye's northernmost tip
Sinop is a port city built on the isthmus of the Boztepe Peninsula, just east of İnceburun, Anatolia's northernmost point. Castle walls carrying the legacy of ancient Sinope surround the city; within them, the historic prison, the Seljuk-era Alaaddin Mosque and Pervane Madrasa, and the Archaeology Museum can be explored on foot. Just west of the city lie the fjord-like Hamsilos cove, İnceburun Lighthouse and the lagoon lake of Sarıkum. Inland, the Tatlıca Waterfalls in Erfelek, climbed step by step, Boyabat's castle on a rocky hill and its basalt columns, and the forests of Ayancık complete the nature routes. Dishes such as lakerda (cured bonito), mantı and nokul are highlights of the local cuisine.
