Thassos island is only accessible by ferry boat and has two ports, Skala Prinos and Limenas (Thassos Town) which are serviced respectively from Kavala and Keramoti on the mainland.
The fastest route is from Keramoti to Limenas (Thassos Town), with a journey time of just 35 minutes and frequent sailings, every half an hour during the summer, this is the preferred route of many visitors to Thassos. Once you get off the ferry enter the ringroad & follow the signs towards Prinos or Limenaria. Stay your course and pass through all the other villages until you reach your destination, Potos.
Thassos does not have its own airport but benefits from the nearby Kavala (Megas Alexandros) airport, from the airport to Keramoti port is a short taxi or hire car journey. Many tourists also choose to fly to Thessaloniki airport (International Airport Makedonia), this is the second largest airport in Greece and benefits from many budget airlines. From here you can take a bus to the coach station and from there, it is a 2-hour KTEL coach ride to Kavala, or hire a car and drive to either Kavala or Keramoti ports.
The Odos Ignatia (E90) runs across the north of Greece, from Igoumenitsa to Turkey and passes both Kavala and Keramoti
