Welcome To Athens!!!
Just in front of each terminal there are plenty of taxis for your demand responsive transport.
If you are more than one or maximum two persons we recommend you the demand responsive transport with a taxi-bus.
For that purpose you will have to visit one of the many agents that are located in the airport.
If your flight is coming late at night and you need assistance for your transportation, drop us an email and we will take care of that.
Of course the best option is to hire a cheap car as this is something that you will need for your transportation from and to the dive sites, but also it will give you the freedom to visit several Athens sightseeing.
Again you can do it by yourself by going to the agents that are in the airport, but we can assist you too.
