A mysterious old city Have you ever wondered what it would be like to step back in time and live like a Greek in an ancient place? Kavala is the place to do exactly that (and more). Northern Greece’s second largest city is just a few hours by car from Thessaloniki and as it’s a hilly, port city it’s vibe is (for lack of a better term) romantic. A mere 62 miles from the Bulgarian border, It’s the gateway to the island of Thassos, famous for its snow white marble. A mysterious old city with winding cobblestone streets and a real Greek flavor, it’s a dreamy place where in summer ferries embark to the island of Samothrace.
