The short version
Greece follows Schengen area rules. For a great many nationalities that means travel without a visa for up to 90 days in any 180-day period, as a tourist, to visit family or friends, to attend business meetings or cultural or sporting events, or for short-term study or training. Working is a different matter and needs a different permission.
The ninety days are not Greek
This is the part worth reading twice, and the reason a Greek page has to talk about other countries. The allowance belongs to the Schengen area as a whole. Time you have already spent in any Schengen country during the previous one hundred and eighty days counts against your ninety, and if your trip continues into Italy, France or anywhere else in the area, the whole visit has to fit inside the same limit.
It is also a rolling window rather than a calendar year: the one hundred and eighty days are counted backward from whichever day you are standing on. For a single holiday the arithmetic will never trouble you. For repeat trips, or a long run around Europe, it is the constraint that decides the itinerary, and border officers do the sum properly. Overstaying can bring a ban of up to three years from Schengen countries.
For a longer stay you must apply to the Greek authorities for a national visa. A residence permit or long-stay visa does not count toward the ninety days.
Your passport has to pass two separate tests
Both of these are in the FCDO's guidance for British citizens, and both are easy to fail while holding a passport you think of as valid:
- the date of issue must be less than ten years before the day you arrive. A passport renewed before October 2018 can carry extra months and therefore an issue date more than ten years old, which makes it invalid for entry however much time is left on it
- the expiry date must be at least three months after the day you plan to leave the Schengen area
You will be refused entry without a valid travel document, or with a passport that has been reported lost or stolen. Check with your travel provider that your documents meet the requirements, and renew early rather than late.
If you are not a British citizen
Everything above is the UK government's understanding of the rules for people traveling on a full British citizen passport. The Greek authorities set and enforce entry rules, and the terms differ by passport. If you hold a US passport, a second nationality or a residence permit rather than a citizenship, confirm your own position with the Greek Embassy before booking rather than assuming the rule transfers. We do that check with you as part of planning.
You may be asked to prove the trip
The FCDO notes that you may also need to show a return or onward ticket and prove that you have enough money for your stay. Carry both where you can reach them rather than in checked baggage.
The Entry Exit System
The European Union's Entry Exit System, or EES, is being implemented across the Schengen area. We publish no start date for it, because the source does not give one and a date remembered from a news story is the fastest way to be wrong in print.
What the guidance does say: registration is free; on a first visit you may be asked to register biometric details such as fingerprints and a photograph at a booth before the immigration desk; you may be asked for a fingerprint or photograph when you leave; children aged eleven or younger will not have fingerprints taken but can be asked for a photograph; a digital record lasts three years; and the system replaces the manual passport stamp for short stays. Nothing needs doing in advance, but allow extra time at the border in both directions, and extra time to reach a departure gate, because checks can happen before boarding.
There is a Greek footnote worth knowing. Greek authorities have indicated that they will not collect biometric data from UK travelers as part of EES. That is an indication rather than a promise, so follow the instructions of the officials in front of you. Long-term residents of a Schengen country are exempt from EES everywhere in the area and should carry the documents that prove it.
Customs, food and cash
There are strict rules about what may be brought into and taken out of Greece, and anything prohibited or liable to tax or duty must be declared. You cannot take meat, milk or products containing them into EU countries. The exceptions are narrow: powdered baby milk, baby food, and special foods or pet feed needed for medical reasons.
Money has a threshold. Declare cash or traveler's checks at your point of entry if you are carrying a value of 10,000 euros or more, complete the forms the customs authority gives you, and ask for a certified copy to keep. Without it, your money can be seized when you leave.
