I've given you your options for getting from Piraeus to the city on your other thread. With the tickeybyou can use it anywhere within the city.
I Know i can use it to athens major areas as in fact we bought that ticket and also used it on the coastal Road .... what i wish to know is if from pireaus we can use it to go somewhere furthur of piraeus not to Athens Centre ...We can have only one day to visit Athens main centre .. as we are planed to use the other 3 day to explore the islands
5-day ticket is valid for all modes of transport in the generic Athens and Piraeus areas, except for Airport lines and bus line Χ80. By Athens and Piraeus we don't mean strictly the municipality areas but the generic metropolitan area, so you may visit outer suburbs such as say Perama or Glyfada or Voula or Kifissia or MAroussi or whatever.
