How can you travel to Kavala?

There are several ways - beyond driving in (if you're coming from Greece). The first is by air. Then it's by bus or a combination of rail and bus/drive.

1. If you fly into Thessaloniki airport then estimate also a short drive to Kavala. If you are not planning to have a car (if you need one let us know and we might be able to help), you can also take a bus (called KTEL). Usually during summer, they run on the hour every hour with the last one (except on Sundays) being at 10pm. But I would suggest checking the schedule directly at the Kavala KTEL (google KAVALA KTEL dromologia) so that the program is up-to-date. The ticket to Kavala via the KTEL bus costs 15 euros - and there's a discount if you buy a return ticket. Don't forget to estimate the distance from the airport to the KTEL station Macedonia of Thessaloniki (which takes one hour by public transport depending on traffic). For the public transport in Thessaloniki (which is a bus), you can get a ticket from the kiosk at the airport or from inside the bus (it costs 2 euros but I think you should have them precisely because the machine on the bus does not give change).
2. If you fly into the Kavala airport - it usually has flights to/from Athens too - it is a bit more difficult to get to Kavala's city centre than from Thessaloniki. Kavala's airport is outside the city, in Chrysoupoli. And there is a shuttle bus only for Olympic / Aegean flights (usually at 8 am and 8 pm). So if you are not coming with Aegean or another flight around these hours then let us know and we will try to come and get you. Otherwise, there is the option of a taxi or KTEL bus with a transfer (which won't be very comfortable in August). In Greece you won't find Uber but there's another app called beat. A taxi from the airport costs around 40 euros. The journey from the airport to the centre takes 20 minutes by car or 45 minutes by bus.
3. You can come by a KTEL bus from Thessaloniki (from Makedonia station). They take about 2 hours - if you can take the express bus which takes exactly 2 hours. Usually, during summer, they run on the hour every hour with the last one (except on Sundays) being at 10pm. But I would suggest checking the schedule directly at the Kavala KTEL (google KAVALA KTEL dromologia) so that the program is up-to-date. The ticket to Kavala via the KTEL bus costs 15 euros - and there's a discount if you buy a return ticket.
4. If you are coming from Athens, you can come either by bus directly (which arrives twice a day and the single ticket is 55 euros (advance return has a discount) or by train to Thessaloniki (39 euros per ticket) and then by KTEL bus (from Makedonia Station). The train station in Thessaloniki is close to the KTEL Macedonia - it takes a maximum of 20 minutes by car. You can also fly to Kavala or Thessaloniki and follow the above instructions. You can come by a KTEL bus from Thessaloniki (from Makedonia station). They take about 2 hours - if you can take the express bus which takes exactly 2 hours. Usually, during summer, they run on the hour every hour with the last one (except on Sundays) being at 10pm.
