Depending on where the ship docks (we docked in the working docks a free bus took us to the town) a pleasant walk is past Bettys Cafe (pick up a free map this does help) along the quay ,we then went into the town via some steps that went to a monument and wandered around the town, (we did notice that lots of the stores were shut) but if you find the main street, quay at one end fountain at the other, there were quite a few shops open along there.

The ship docked right in the port so it's about a 10 min walk into the town (the ship does organized trips to Olympia if you are not confident of exploring) (or there were loads of coaches offering trips to Olympia or various other tours. Having done research beforehand we knew there was a trolley train that took you to a winery then a beach. To locate this go right to the end of the main street, turn right, and they are located there (the winery is not bad, did not get off at the beach as it was about to rain).

Nice touristy shopping in the town.

You are transported via dedicated tender boats to the port, you then have the option of a walk up 588 steps!! Riding a donkey part way, or cable car (we chose the cable car 6 euros each very quick and very efficient). If you feel up to it there is an option of a very nice walk to the next village (Imerovigli) via the coastal paths we were able to see some of the true beauty of Santorini this way. Or take a lovely boat ride to Oia and a bus ride around the island and back to the top of the hill overlooking the port for about 15 Euros, and just walk/donkey/or cable car down.

We had a map but as the town is so compact and very busy it was not necessary (very touristy and it seemed quite expensive.

Depending on what you wish to do (we opted for the hop on hop off bus the blue one) these are located to the left once you exit the main terminal building about a 5 minute walk.

There are 3 different companies Greyline (yellow bus the one MSC uses)(red hop on hop off)we opted for the blue one as we had picked up a leaflet in a previous port of call.

There was a 40 minute trip around Piraeus (where you could hop on and hop off if you wished) then the main tour started just below the Acropolis, and went around Athens, which took about an hour and 40 minutes

As Athens was so busy we decided just to stay on the bus. The tour was very informative and well worth the money paid.

When we returned to Piraeus we had a look around the local town which is quite pleasant.

We had visited here before and done research so we opted for the local bus no 16 cost 1.70 euros into town (good 10 -15 minute walk from ship to where the bus was located.

Very nice place to walk around good maps on display

The ship docks right in the town again. We had done research and printed up a map This again was unnecessary, just walk to the left were you will locate the ancient town as its very compact. Nice to walk round, lots of history (most shops seemed to be open even though we docked so early.) An open air market with lots of fruits, vegetables, cheeses, flowers etc. was just outside the city walls.

There is a shopping mall about 200 meters to the left good for designer items but not much else.
