On the newly constructed road "Egnatia Odos" on the way to and from Alexandroupolis there is only ONE petrol station. To reach this petrol station you have to follow the sign "exit" at MOUSTHENI (a village between Kavala and Thessaloniki). The prices of the petrol station, run by SHELL (service 24 hours), are a little bit higher than normal prices. So, it is more wise to fill up the tank of your car before the trip to and from Alexandroupolis, instead of searching for petrol station in any junction (this purposes that you get out of "Egnatia Odos" and then you come back on it). Beside the petrol station there are two restaurants serving coffee, meals, snacks, sandwitches, sweets and local products ("kourabies" and "tsoureki"). Toilets in both of them are clean and safe. The regular bus line between Alexandroupolis and Thessaloniki stops here, too.
Car hire and taxi services are available to get from the Airport to the city.
Use buses or taxis if you want to get around.
