How to get there
Thassos may be reached in different ways, but you always have to take the ferry because the island has no airport. 

You can book flights - among others - with

The nearest airport.
With Thomson from Birmingham, London Gatwick, Manchester.
With Aegean from London Heathrow.

There are more possibilities to fly to Thessaloniki. 
With Thomson from East Midlands, London Luton + Gatwick, Manchester.
With EasyJet from London Gatwick.
With Aegean from London Heathrow.
With German Wings from London Stansted + Heathrow, Manchester.
With Ryan Air from London Stansted.

From Thessaloniki you will have to drive another 2 hours to the ferry.  It is a nice and easy drive because recently a new motorway has been opened.
It is possible to rent a car in advance from  Potos CaRental at a reasonable price, (either for the days of arrival and departure and throughout your vacation), which will be waiting for you at the airport of Thessaloniki. Or you can take the bus or a taxi. 

From the airport Megas Alexandros (Kavala) you take a taxi to the ferry in Keramoti. You buy your ticket there and wait till the ferry leaves.  In the summer season normally every (half) hour, outside season every one or two hours.  It takes approximately 40 minutes to reach Limenas. Your holidays starts before you arrive in the capital of Thassos! There you take another taxi, which will take you to your accommodation in Kalivia/Limenaria in approximately 40 minutes. Or you arrange a rental car to be waiting for you and drive yourself! 
You can also make arrangements with us to transfer you from and to the ferry port.
We can provide you with a clear itinerary or help you in reserving a rental car.
