Sinop is best seen by walking; it's a very nice town of quaint stores, small mosques, hidden tombs, parks and historical sites. Visit the ruined Hellenistic temple and the site where Diogenes, the seeker of honest men, was born. Also see the Aladdin Keykubat Mosque, ruins of the Serapis Greek temple and a Hittite citadel. Sinop merits a half-day visit. 190 mi/305 km northeast of Ankara.
