Both, depending on the itinerary. Many Eastern Mediterranean and Greek Isles cruises homeport in Piraeus, so it's your embarkation or disembarkation day. Others stop here as a regular port call for Athens. Check whether your day in Piraeus is a full day or a six-hour window — it changes how much of Athens you can realistically see.

Budget about three to four hours for both — the Acropolis itself is a steady uphill walk and gets brutally hot and crowded by midday, and the Acropolis Museum at its base deserves at least an hour. If your ship is in port for a short call, prioritize the Acropolis and skip Cape Sounion.

Yes, but only with a full day. Cape Sounion and its Temple of Poseidon sit about an hour and a half south of Athens by road, so it works best as a private transfer or organized excursion. If you only have a standard port call, it's tight — most people pair the Acropolis and Plaka instead and leave Sounion for a longer stay.

Generally yes — Line 1 to Monastiraki is straightforward and well used by tourists and locals alike. The usual big-city advice applies: watch your bags and pockets on crowded trains and at busy stations like Monastiraki and Omonia, where pickpocketing is the main nuisance. Buy a ticket before boarding and keep it until you exit.

If you have spare time before sailing, head to Mikrolimano — a small, curved harbour ringed with fish tavernas, far quieter than the cruise terminal. The Archaeological Museum of Piraeus is also nearby. But be realistic: Piraeus is a working port town, and most of what people come for is up the road in Athens.

Greece uses the euro (EUR). Cards are widely accepted at museums, larger restaurants, and shops, but carry some cash for small tavernas, kiosks, metro tickets from machines, and tips. ATMs are easy to find in central Athens and around Piraeus station.
