First, it should be emphasized that Greece is one of the safest destinations for the traveler: the vast majority of people you interact with will be honest and helpful. The detailed information below is intended to forewarn travelers of risks which they have a small, though not zero, chance of encountering.
Crime and theft
Violent crime and theft rates are very low; public disorder is rare, and public drunkenness is generally frowned upon. Visitors should rest assured that this is an extremely safe and friendly destination, but it is always advisable for foreign tourists to exercise basic precautionary measures just as they would at home. There has recently been a spike in theft (at least a perceived one), which some locals will not hesitate to blame on the influx of immigrants.
The places where the visitor is most likely to encounter crime and theft are probably the handful of overcrowded, and overheated, tourist resorts thronged with younger foreigners attracted by cheap flights, cheap rooms, and cheap booze. The more notorious of such places include Faliraki in Rhodes (calmed down since a new tough mayor was elected), Kavos in Corfu, Malia (currently the “hottest” such destination) on Crete, and Ios (though this last is said to have quieted down a bit recently.) Most visitors to these places return home unmolested, but there have been increasing reports from them of theft, public indecency, sexual assault, and alcohol-fueled violence; the perpetrators as well as the victims are usually young foreigners, though sometimes locals are involved. Authorities have stepped up police presence in such areas to crack down on these activities. Still, visitors to these places would do well to avoid anything that looks like trouble, especially late at night, and to remember that their own overindulgence in alcohol increases their chance of attracting trouble themselves.
Scams
The most commonly reported major scam against travelers is the Greek version of the old clip joint routine. This is reported primarily from central Athens, but also occasionally from other cities and even the larger island towns. A single male traveler will be approached, usually at night in a neighborhood where there are a lot of bars, by a friendly Greek who will strike up a conversation leading to an invitation to go to “this really cool bar I know” for a drink. Once at the bar, they are joined by a couple of winsome ladies who immediately begin ordering drinks, often “champagne,” until, at the end of the evening, the mark is presented with an astronomical bill, payment of which is enforced by the sudden appearance of a pair of glowering thugs. The reason this scam works is because most Greeks have a tradition of being friendly to visitors, and almost all Greeks who strike up a conversation with you will have no ulterior motives. But if you’re a single male traveler approached by a Greek in the circumstances described above, it’s safest to politely but firmly decline any invitations.
Photography restrictions
It is strictly forbidden to take photos of military installations or other strategic locations. Authorities will take violations quite seriously. Obey signs prohibiting photography. In fact, it would be best not to take photographs of anything of military significance, including Greek navy ships, or of airports or any aircraft, even civilian ones: Greek authorities can be very sensitive about such things. Many museums prohibit photography without a permit; some prohibit only flash or tripod photography, and many ask visitors not to take photos of objects (statues, etc.) which include people standing by them, as this is considered disrespectful. But these specific cautions shouldn’t discourage visitors from otherwise taking photos in Greece, which is one of the most photogenic places in the world.
Antiquities
Greece also has very strict laws concerning the export of antiquities, which can include not only ancient objects but coins, icons, folk art, and random pieces of stone from archeological sites. Before buying anything which could conceivably be considered an antiquity, you should become familiar with the current laws regarding what can be taken out of the country. Do not ever think to export or buy any piece of archeological value because it will be either be a fake or you will be arrested promptly at the airport for trafficking of goods of archeological value.
Drugs
Greece has some of the strictest, and most strictly enforced, drug laws in Europe, and tourists are not exempt. No matter what anyone tells you, it is most definitely not cool to do drugs in Greece, including marijuana. Furthermore, such a behaviour is strongly rejected by locals and will almost certainly cause someone to call the Police and have you arrested. Note that even a very small quantity is enough to get you in serious trouble. Don’t even think of offering even the smallest amount of drug to someone else. You risk being prosecuted with charges of drug dealing, leading to several years of imprisonment!
Traffic
The greatest danger to travelers in Greece is probably in the simple process of crossing the street: traffic can be bad even in smaller towns and horrendous in Athens and other Greek cities, and accident rates are high. Caution should be exercised by pedestrians, even when crossing with a walk light.
