Public transportation has improved rapidly after Olympics of 2004, especially with the operation of Metro Lines. Except Metro there is also a tram system, suburban train, and a large network of buses and trolleys. Buses and tram are an excellent way to move to the south coastal route and arrive at the beaches outside Athens. Tip: the updated site of OASA (Athens Urban Transport Organization. You will find there, all the information you may needed about routes, tickets and times regarding all means of public transport: metro, train, tram, buses, and trolleys. Information about traveling from Athens airport to the center or port (or wherever). Also on some bus stops there is a timetable which shows what time the bus will come.
