Greece brings together ancient history, sun soaked islands, and welcoming towns, which makes planning a trip both exciting and full of choices. A little practical knowledge goes a long way and sets you up to enjoy the country’s archaeological sites, beaches, and lively neighborhoods without stress.
These essentials cover entry rules, money, transport, seasons, and on the ground etiquette across the mainland and the islands. Use them to build an itinerary that fits your budget and pace while leaving room for ferries, long lunches, and time at the water.
Greece and the Schengen Area
Greece is part of the Schengen Zone, which means border free travel for visitors arriving from other Schengen countries. EU and EEA nationals can enter with a national ID, while many non EU travelers either enter visa free for short stays or need a prearranged visa depending on nationality and length of stay.
Your passport should be valid well beyond your planned departure and it is wise to carry a copy or digital scan. Keep the passport with you for hotel check in and domestic flights since identification is required for boarding and for some ticket purchases.
Currency and Payments
The currency is the euro and cards are accepted widely in cities, airports, and most island hubs. Small family businesses and kiosks may prefer cash for low value purchases, so plan to carry some notes and coins for taxis, sunbeds, markets, and tiny bakeries.
ATMs are common in towns and ports. Choose to be charged in euros when a card terminal offers a currency choice so you avoid extra conversion fees, and enable contactless payments on your phone as many terminals support tap to pay.
Language and Signage
Greek is the official language and you will see signage in Greek script along with Latin transliterations on highways and at major sites. In tourist areas many people working in hospitality speak English, and you will often find menus in several languages.
Learning a few basic phrases such as good morning and please makes everyday interactions smoother. Street names can appear in both scripts, so match the Latin transliteration on your map with the Greek sign and confirm with a landmark when in doubt.
Power Plugs and Voltage
Greece uses Type C and Type F plugs on a 230 volt supply at 50 hertz. Bring a compact adapter if your devices have a different plug type and check that chargers and electronics list 100 to 240 volts to avoid damage.
A small power strip can help when outlets are limited in older buildings. Consider a power bank for long days on ferries and at beaches, since shade and outlets are not guaranteed.
When to Go
Summer brings long days and very warm temperatures, especially from late June to August. Shoulder months such as May and October offer milder weather and fewer crowds, and many hotels and ferries still run frequent services.
Some islands wind down in winter as seasonal businesses close. Mainland cities remain lively year round, and you can pair cultural visits with day trips to nearby coastlines without peak season crowds.
Heat, Sun, and Hydration
UV levels are strong and midday sun can be intense. Wear a hat and sunglasses, apply high SPF sunscreen, and plan indoor or shaded activities around noon with more walking in the morning and late afternoon.
Carry a refillable bottle where tap water is potable and add electrolyte tablets during very hot days or hikes. For beach time, alternate sun exposure with shade and check for posted flags that indicate swimming conditions.
Wildfires and Emergencies
Dry summer conditions can lead to wildfires in rural and island areas. If you see smoke or smell strong burning, move away from hillsides and follow instructions from local authorities and hotel staff.
Know the European emergency number 112 for fire, medical, and police. Keep accommodation details and a meeting point handy, and enable government alerts on your phone so you receive local warnings.
Earthquakes and Safety Basics
Greece is seismically active and mild tremors can occur. If you feel shaking, move away from windows and heavy furniture and use the drop, cover, and hold approach until the movement stops.
After a tremor, avoid elevators and check for falling debris when going outside. Hotels and museums post evacuation routes, so take a moment to note the closest exit when you arrive.
Ferries and Island Hopping
Ferries connect Athens and regional ports with the islands on regular routes. Services are busiest in summer, so secure seats or cabins early for popular lines and plan extra time to board at Piraeus, Rafina, or Lavrio.
Weather can affect sailings, especially with strong seasonal winds in the Cyclades. Keep a flexible plan with buffer time between a ferry arrival and flights or onward travel, and print or download tickets in advance for quick checks at the gate.
Domestic Flights and Airports
Domestic flights link Athens and Thessaloniki with larger islands and regional cities. Flight times are short and can be an efficient option when islands are far apart or ferries are limited.
Allow time for security and checked bags even on short hops. Pack valuables and medicine in your carry on and keep photo ID ready, as staff will verify it during check in and boarding.
Buses and Trains on the Mainland
Intercity buses known as KTEL cover most mainland routes and connect towns where trains do not run. Stations post timetables and sell reserved seats, and luggage is stowed underneath with a claim tag.
Rail service links major cities and offers scenic stretches in northern and central regions. Buy tickets ahead on busy weekends, validate any paper tickets if required, and keep a small snack and water for longer rides.
Driving and Car Rental
Driving is on the right and seat belts are mandatory. An International Driving Permit can be required for renters from certain countries, so check your eligibility and carry both your home license and the permit.
Roads range from modern toll motorways to narrow village lanes. Parking is limited in old towns, scooters and ATVs are common on islands, and alcohol limits are strict, so choose a designated driver or use taxis after dinner.
Tap Water and Food Safety
Tap water is generally safe to drink on the mainland and in larger islands, while smaller islands may rely on delivered water. Ask your host or check hotel guidance in each destination and use refill stations where provided.
Fresh produce, grilled meats, and seafood are staples. Choose busy tavernas with good turnover, confirm fish prices which are often listed by weight, and expect bread and water placed on the table to appear as small items on the bill.
Beach Etiquette and Safety
Many beaches offer sunbeds and umbrellas for a daily fee, while public areas remain free for towels and umbrellas you bring. Respect posted swimming zones and watch for local currents or rocks at the waterline.
Follow rules about protected dunes and nesting areas where access is restricted. Music volume and drones are often regulated, and lifeguards may set flags to indicate conditions that limit swimming or water sports.
Cultural Etiquette at Churches and Monasteries
Dress modestly when visiting monasteries and active churches. Shoulders and knees should be covered, and some sites provide wrap skirts or shawls at the entrance.
Photography rules vary and flash or tripods may be restricted. Move quietly, avoid touching icons or frescoes, and follow the indicated path to keep visitor flow steady in small interiors.
Eating Out and How Menus Work
Meals often start later than in northern Europe and a relaxed pace is normal. Meze plates encourage sharing, and house wine or carafes are common choices in casual tavernas.
Fish is frequently priced by the kilo and staff will weigh your selection before cooking. Daily specials and oven dishes may be displayed inside, so look for a counter or ask to see what is available that day.
Tipping and Service Charges
Tipping is not mandatory but is appreciated for good service. Rounding up the bill or leaving a small percentage in cash is typical, especially where card terminals do not include a tip option.
Some restaurants add a cover charge that includes bread or table service. Review your receipt before paying and keep small coins for cafés and snack bars where table staff cycle through many short orders.
Connectivity and SIM Cards
Mobile coverage is strong in cities and popular islands. Tourist SIM packages are available at airports and phone shops and require ID, and many hotels and cafés offer free Wi Fi.
Download offline maps for islands with patchy service and keep ferry bookings and hotel confirmations accessible without a connection. A compact travel router can extend a single hotel login to multiple devices in your room.
Museums and Archaeological Sites
Major sites use timed entry during busy months to manage crowds. Buying a combined ticket can give access to several landmarks within a set period and helps you spread visits across cooler parts of the day.
Opening hours change between summer and winter schedules. Check the first entry times if you want to take photos before groups arrive and expect reduced hours on certain public holidays.
Strikes and Schedule Changes
Transport strikes can affect ferries, buses, and services at ports or airports. Build in a cushion day when island hopping and keep alternative routes in mind, such as an earlier ferry or a flight if weather or labor actions disrupt travel.
Hotels and tour operators usually share updates quickly, but you should also monitor notices at stations and ports. Keep essential items like medication and one change of clothes in your day bag in case plans shift on short notice.
