The Harbour itself is not particularily attractive, being a functional busy port, however, there are plenty of oportunities to take a good look at the variety of ships in port, from the pleasure cruisers of the rich, to the rusting ships of old cargo companies.
The port has very good security with police and luggage scanners at the terminal building. For passengers wishing to go freestyle and explore on your own, there are maps on the termianl wall to help and a large taxi rank outside the terminal door.
There are also trains into Athens, as roads can get very busy at peak times. Athens has a huge host of ancient buildings to visit and explore, some of these are instantly recognisable, such as the Acropolis, which dominates the skyline for miles to the National Garden and the Zappeion
Transport is easy to find and use and although most taxi fares are standard, there is some room for haggling. For instance, on one ship, the tour to the Corinth canal was cancelled. The trip had orginally been sold by the shore excursion staff as £40 per person, we managed to do a deal with a driver for €80 for three of us. This included the 60 mile drive to the canal, but also some time on the bridge and a look around the old city.
By undertaking the more personal small trips, especially in taxi's, it's possible to see more and get a veyr personal service. We were able to pause and watch the bungee jumpers over the canal, and watch local people going about their business rather than being herded as a large group.
