There is no airport on Thassos. Flights go to Kavala International Airport on the mainland opposite the island. Olympic Holidays offer an optional “taxi” extra which includes taxis and the ferry between airport and the accommodation. There’s a 15-minute taxi ride from the airport to the port at Keramoti and a 40-minute ferry crossing to Thassos Town. Ferries from the port in Kavala take an hour-and-a-half and go to Skala Prinou, the other port on Thassos.
