Piraeus, Greece (Athens)

Cruise ships dock at the New Passenger Terminal, one mile from the center of Piraeus and eight miles from Athens. The 2 terminals A and B are less than a half kilometer apart. Free shuttles, if you are docked further away will drop you off at the main cruise terminals buildings.
Cruise organized shuttles to Athens will be announced the night before.

Athens Hop-on Hop-off Tour starts at about 200 meters from the cruise terminal. Turn left from the cruise terminal building (lower level) and walk over the parking lot. There is also a little tourist train here, but only travels through Piraeus.

Metered taxis are generally available just outside the terminal building. Prepare to negotiate.

Sights

  • Acropolis - No visit to Athens is complete without heading to the Acropolis. There are a few temples at the top with the most famous being the Parthenon. Your ticket will include entrance to other archaeological sites including the Agora and South Slope of the Acropolis/Theatre of Dionysos. Since you will pass the South Slope entrance if walking from the Akropoli metro, buying your ticket here could bypass the potentially longer lineups at the main Acropolis ticket office. Getting to the Acropolis early will avoid the crowds, tour groups, and hotter weather later in the day. Admission is €12. Opens at 8am daily in the summer but later at 11am on Mondays. Main entrance is on the west side signposted from either Thissio or Akropoli metro. Link here.
  • Acropolis Museum - This new museum at the foot of the Acropolis showcases some of the site's treasures still remaining in Greece. Be sure to catch the film on the top floor and the original Erechteion statues. Open Mondays for summer tourist season only but not late. Admission is €5. Link here
  •  Syntagma Square - This is the city's central square. Beside Syntagma are the parliament buildings where you can catch the changing of the guard. If you are there on a Sunday, there is a more elaborate ceremony at 11am. Syntagma Square is also the site of most government protests so check the news before you visit unless you like the smell of tear gas.
  • National Archaeological Museum - This museum houses Greek's famous antiquities. Five minutes from Metro Viktoria. Admission is €7. Opens later at 12:30pm on Mondays. Link here.
