Greece Travel Essentials: The Complete Pre-Trip Preparation Guide

Most Greece travel essentials guides are packing lists. This one is not. A packing list tells you to bring sunscreen and comfortable shoes — things you already know. What makes the difference between a good Greece trip and a genuinely extraordinary one is the preparation that most guides skip: understanding how Greek money actually works, knowing what the Meltemi wind is and how it affects your ferry, understanding the monastery dress code before you’re turned away at the door, knowing which SIM to set up before you land, and having the specific logistical intelligence about Greek public transport, pharmacies, tipping culture, and emergency contacts that every visitor needs but nobody explains properly. This guide covers all of it. Read it before you go.

Documents and Entry Requirements

Who Needs What to Enter Greece

Greece is a Schengen Area member. EU and EEA citizens enter with a national ID card or passport. No visa required. UK citizens (post-Brexit) enter with a valid passport for stays up to 90 days in any 180-day period — no visa currently required, but the EU’s ETIAS (European Travel Information and Authorisation System) is expected to launch in late 2026. When implemented, ETIAS will require UK, US, Australian, Canadian, and other non-EU visa-exempt nationals to obtain an electronic travel authorisation before arrival (expected cost approximately €7, valid 3 years). Check the current ETIAS status at travel-europe.europa.eu before booking. US, Australian, and Canadian citizens currently enter with a valid passport, no visa, 90 days maximum.

Documents to Carry

Passport or ID card — valid throughout your stay, carried at all times. Travel insurance certificate — carry a printed copy. For EU citizens: EHIC or GHIC card for healthcare at Greek public hospitals. Driving licence if renting a car — an international driving permit is not required for EU/UK/US/Australian licences at most Greek rental companies, but carry your home licence regardless. Ferry booking confirmations — downloaded to your phone before you leave. Accommodation booking confirmations — offline accessible.

Make digital copies of everything. Scan your passport photo page, travel insurance policy, and credit cards front and back. Store them in your email, in cloud storage, and on your phone. If your bag is stolen, these copies allow you to proceed with your trip while waiting for replacements.

Money: How Greece Actually Works

Greece uses the euro (€). This section covers the practical money knowledge that generic guides skip.

Cash Is More Important Than You Think

Greece is more cash-dependent than most Western European countries. The specific situations where cash is essential and cards are not accepted:

Monastery entry fees — all Greek monasteries charge entry in cash only. Budget €3-6 per monastery. ATM cards and credit cards are not accepted at any Greek monastery without exception. Smaller island tavernas and kafeneions — particularly in villages away from the main tourist circuits. The smaller the operation, the more likely it is cash-only. Beach sunbed rentals at smaller, non-commercial beaches. Island bus tickets in some cases. Street food (souvlaki, koulouri, loukoumades vendors). Market stalls at the Monastiraki flea market and equivalent markets on islands. Tips at restaurants and taxis — always cash.

The practical rule: always carry €50-100 in cash when leaving your accommodation for a day of sightseeing or beach-going. Never rely exclusively on cards in Greece. ATMs are widely available in Athens and on major islands. On smaller islands and in inland villages, ATMs may be limited to one or two machines. Withdraw sufficient cash before leaving the main port town.

ATM and Card Strategy

Greek ATMs sometimes offer “dynamic currency conversion” — a prompt asking whether you want to pay in euros or your home currency. Always choose euros. The bank’s exchange rate is always better than the ATM’s conversion rate. Choosing your home currency at a Greek ATM typically costs 3-5% extra. Greek ATMs frequently charge a withdrawal fee of €2-5 on top of whatever your bank charges. Minimise this by withdrawing larger amounts less frequently rather than small amounts multiple times.

Credit cards are accepted at hotels (almost universally), larger restaurants and tourist shops, ferry ticket offices, and car rental companies. Visa and Mastercard are universally accepted where cards work. American Express is accepted at some but not all establishments. Contactless payments work at most urban card terminals.

Connectivity: The Most Important Preparation

Set Up an Airalo eSIM Before You Fly

This is the single highest-impact preparation action for a Greece trip. An Airalo eSIM activates the moment your plane lands at Athens airport — giving you Google Maps, ferry schedule checking, accommodation booking apps, and Beat/Bolt taxi-hailing from the moment you exit the aircraft. Without it, you are navigating an unfamiliar airport with no connectivity until you find a SIM shop or activate international roaming at your home carrier’s premium rates.

The specific Greece case for Airalo: the trip typically covers multiple islands, each with potentially different connectivity from your home SIM’s roaming arrangement. An Airalo eSIM covers all Greek islands on a single Greek data plan without configuration changes or roaming charges between islands. The cost is significantly less than most home carrier international roaming plans. Set it up on the Airalo app, download the Greek or European plan, activate on landing. Compatible with all modern smartphones (iPhone XS and later, most Android flagships from 2019 onward). If your phone requires a physical SIM, buy a Greek SIM card at the Athens airport (Vodafone, Cosmote, or Wind kiosks at arrivals).

Apps to Download Before Departure

Beat — Athens taxi-hailing app, the most reliable ride-hailing in the city. Connect a payment card before arrival. Essential for airport arrivals, late-night returns, and any journey where a confirmed ride beats a taxi queue.

OASA Telematics — real-time Athens bus tracking app. Shows live bus positions at every stop. Essential for bus navigation in Athens since published schedules are unreliable but live tracking is accurate.

Google Maps offline — download the Greece map (or Athens + each island separately) on WiFi before departure. Works without data for walking and driving navigation. Greek street signs use both Latin and Greek script in tourist areas but Greek-only in residential areas. Offline maps eliminate navigation anxiety.

Google Translate with Greek offline pack — the camera translation function (point at Greek text, see translation overlaid) is genuinely useful for menus, street signs in residential areas, pharmacy labels, and ferry terminal signs. Download the Greek language pack for offline use.

Ferryscanner — book and manage all ferry tickets. Download boarding passes to the app before reaching the port. Real-time cancellation and delay notifications. Essential for island-hopping itineraries where weather can affect schedules.

What to Pack: The Greece-Specific List

This is not a generic packing list. Every item here addresses a specific Greece challenge that generic lists miss.

Footwear — The Most Important Category

Proper walking shoes — non-negotiable. Athens, every island capital, and every archaeological site involves cobblestones, uneven ancient stone, and sloped surfaces that destroy fashion footwear. The Acropolis specifically has smooth marble slopes that become dangerously slippery when polished by millions of visitors. Closed-toe shoes with grip are essential for the Acropolis and for any site with stone surfaces. Sandals with straps are acceptable for casual town walking but not for archaeological sites. Flip-flops are appropriate at beaches only.

Reef shoes / water shoes. Greek island beaches are frequently pebbly or rocky rather than sandy. The sea floor at island coves often has sea urchins — stepping on one is genuinely painful and requires medical attention. Reef shoes (thin-soled water shoes that protect the sole while allowing swimming) eliminate both the pebble discomfort and the sea urchin risk. Available cheaply in every island pharmacy and tourist shop, but better to bring quality ones from home.

One pair of smart-casual shoes. Greek island restaurants and the better Athens restaurants have an informal dress code — not formal but not beach clothes. One pair of clean, presentable shoes beyond the walking shoes covers every evening situation.

Clothing

Sun protection clothing. Greece in July-August regularly reaches 38-40°C. Light, breathable fabrics (linen, technical lightweight) make the difference between comfortable and genuinely suffering at the Acropolis at midday. Dark colours absorb heat. Light colours reflect it. Loose-fitting covers more skin and protects better than tight clothing.

Modest clothing for churches and monasteries. Every Greek Orthodox church and all monasteries require covered shoulders and knees for entry. This applies equally to men and women. Women must cover their knees with a skirt or dress (not trousers at some strict monasteries). Men must wear long trousers. Some monasteries provide wrap-around skirts at the entrance — don’t rely on this. Pack at least one outfit that covers shoulders and knees for the sites that require it. If you’re visiting Meteora, this applies to all six monasteries. If you’re visiting island monasteries on your island circuit, carry a light scarf or sarong that doubles as a shoulder and knee cover.

A light layer for ferries and evenings. Greek ferry air conditioning is set to temperatures that are noticeably cool relative to the outside heat. Always pack one light layer — a linen shirt, a lightweight hoodie — for the ferry crossing. Island evenings in May, June, and October can also be cooler than expected after the day heat.

For island hopping specifically: pack light. The maximum for a 10-day island-hopping trip is one carry-on sized bag. Every extra kilogram is carried through ferry ports, up cobblestone streets, and on and off boats. Leave the large suitcase at your Athens hotel (most hotels offer free luggage storage). Travel with a soft bag or backpack that fits in an overhead locker. This single rule transforms the island-hopping experience.

Sun and Heat Protection

Sunscreen SPF 50+. Greek summer sun is intense in a way that catches visitors from northern climates off guard. The specific combination of high UV intensity (Greece is at 37-41 degrees latitude — significantly more UV than the UK or northern Europe), reflective white limestone surfaces at archaeological sites, and reflective water at beaches means that burning happens faster than visitors expect. SPF 30 is insufficient for midday Greek summer sun. SPF 50+ applied every 2 hours is the correct approach. Available at Greek pharmacies (good quality, competitive prices) but expensive at tourist shops and airport pharmacies — bring your own from home.

A hat with a brim. Essential for Acropolis visits, archaeological site tours, and any extended midday outdoor activity. The Acropolis has essentially no shade on the approach path or at the summit. A wide-brimmed hat is not optional in July-August.

A refillable water bottle. Greece has excellent tap water in Athens and on most major islands (it is safe to drink and tastes good). A refillable bottle eliminates the constant purchase of plastic bottles (expensive at tourist sites, wasteful, and unnecessary). Archaeological sites and major tourist areas have water fountains. Fill up before entering the Acropolis.

Health and Pharmacy Items

Your regular medications — enough for the trip plus extra days. Bring more than you think you need. Ferry delays, weather disruptions, and extended stays mean the trip can run longer than planned. Keep medications in their original packaging with a copy of the prescription. Controlled substances specifically require documentation for customs. For specific guidance on medical care in Greece: our Athens hospitals guide.

Rehydration salts. Athens in July-August regularly reaches 40°C. Significant sweating in this heat causes faster dehydration than most visitors expect. Oral rehydration salts (available at any Greek pharmacy, also available from home) are the fastest recovery from heat-related dehydration. Particularly important for days involving significant walking at archaeological sites.

Motion sickness medication if susceptible. The Aegean in July-August has the Meltemi wind — a strong northerly that creates rough conditions on exposed crossings. The Piraeus-Santorini fast catamaran in 5-6 Beaufort Meltemi conditions is genuinely rough. If you have any tendency toward motion sickness, pack medication. Available at Greek pharmacies without prescription, but better to have it before you’re already on a rough boat.

Insect repellent. Greek mosquitoes are present near fresh water and in wooded areas from May-October. Not a major issue in most island accommodation but relevant near rivers, the Strofylia lagoon near Skiathos, and some mainland areas. DEET-based repellents are most effective. Available at Greek pharmacies.

Money and Payments

Tipping in Greece

Greek tipping culture is more relaxed than American equivalents. The practical guide: at sit-down restaurants, rounding up to the nearest €5 or adding 10% for good service is appropriate. At cafés and bars, rounding up to the nearest euro is the norm. At taxis, round up to the nearest euro or add €1 on longer journeys. For private tours: €5-10 per person for an excellent guide. For hotel housekeeping: €2-3 per day, left daily rather than as a single sum at checkout. For Welcome Pickups private transfers: tipping is appreciated but not expected — the service fee is included. Full details in our tipping in Greece guide.

Budget Benchmarks

Current 2025-2026 price benchmarks for planning:

Athens metro single journey: €1.40. 5-day tourist transport pass: €9. Acropolis entry: €20 (€10 reduced). Acropolis Museum: €10. Typical souvlaki: €3-4. Café coffee: €3-4. Taverna dinner per person with wine: €25-40. Upscale restaurant: €50-80 per person. Mykonos/Santorini premium caldera hotel: €300-1,500/night. Mid-range island accommodation: €80-180/night. Budget accommodation: €50-80/night. Fast ferry Athens-Santorini: €45-90. Car rental on island: €40-70/day. Check current accommodation prices through Booking.com — both accommodation and ferry prices vary significantly by season and advance booking.

Getting Around Greece: The Pre-Trip Decisions

Book Your Ferry Tickets in Advance

If your trip involves island hopping, ferry tickets are the first booking to make after flights and accommodation. Not the last. July-August morning high-speed sailings from Piraeus to Santorini and Mykonos sell out 3-4 weeks ahead. Book through Ferryscanner as soon as your dates are confirmed. Download tickets to your phone. Carry them offline — port connectivity is sometimes unreliable. Full guidance on the ferry system in our Greek ferry guide and our island hopping guide.

Book Your Airport Transfer Before Landing

Athens airport to hotel is the first logistics challenge of any Greece trip. Three options: metro Line 3 (40 minutes, €10.50 — best value, requires luggage management), express bus X95 (60-90 minutes, €6.50 — cheaper but slower), or private transfer (Welcome Pickups — fixed price confirmed before landing, driver waiting at arrivals with name sign). For first-time arrivals with significant luggage, the Welcome Pickups option eliminates the stress of navigating an unfamiliar system in the heat after a long flight. Book it before you leave home. Full details in our Athens airport guide.

Book Acropolis Tickets Before Arrival

In July-August, the Acropolis ticket queue at the gate can reach 45 minutes. Booking skip-the-line tickets through GetYourGuide before departure gives you a QR code on your phone that bypasses the queue entirely. Book at least 2 weeks ahead for peak season. The combined Athens archaeological sites ticket (covers Acropolis, Ancient Agora, Roman Agora, Kerameikos, and others) is available online and gives the best value across multiple sites.

Car Rental: Book in Advance for Islands

If your itinerary includes driving on any of the larger islands (Naxos, Milos, Rhodes, Kefalonia, Crete, Lefkada), book through Discover Cars before arrival. Island rental car supply genuinely runs short in July-August — arriving on Naxos hoping to rent a car on the day is a real risk in peak season. Booking in advance locks in price and availability. Bring your home driving licence. Check that your travel insurance covers driving in Greece — not all policies do.

Health and Safety

Travel Insurance

Comprehensive travel insurance is essential for Greece — not optional. The specific Greece risks that make this non-negotiable:

Ferry cancellations in Meltemi weather can strand you on an island for 24-48 hours. Trip interruption coverage protects accommodation and onward travel costs. Medical evacuation from a small Greek island to Athens for serious conditions can cost €5,000-15,000 — standard travel insurance covers this, self-paying does not. EU visitors: your EHIC/GHIC covers public hospital treatment but not private hospitals (where waiting times are shorter and English is more reliably spoken) and not medical evacuation. Non-EU visitors: Greek private hospital treatment is significantly cheaper than US healthcare equivalents but costs accumulate quickly. Ensure your policy covers: medical expenses (€100,000 minimum), medical evacuation, trip cancellation, and baggage loss.

Heat Safety

Athens in July-August is genuinely dangerous in a way that visitors from northern climates underestimate. Temperatures reach 38-42°C. The correct approach: monuments and outdoor activity between 8am-11am and after 5pm. Midday (11am-4pm) in air-conditioned museums, cafés, or accommodation. Drink water constantly — at least 3 litres per day in heat. Recognise heat exhaustion symptoms (dizziness, nausea, weakness, pale skin) and move to shade or air-conditioning immediately. Heat stroke (confusion, very high body temperature, hot dry skin) is a medical emergency — call 112.

Emergency Numbers

112 — pan-European emergency number, English operators available, reaches police/fire/ambulance. Save it in your phone before departure. 166 — ambulance directly. 100 — police. Greek pharmacies (the green cross sign) are the first stop for minor medical issues — pharmacists are trained to diagnose and treat minor ailments and English is widely spoken in tourist areas. Our Athens hospitals guide covers the full medical care picture.

The Greece-Specific Cultural Preparation

Greek Phrases That Transform Every Interaction

Greek is genuinely difficult — the alphabet, grammar, and vocabulary are all different from Western European languages. But three phrases produce immediate and visible warmth in every interaction: Efcharisto (ef-ha-ree-STOH) — thank you. Parakalo (pa-ra-ka-LOH) — please, and also “you’re welcome.” Yassas (YA-sas) — hello and goodbye (formal). Using these in shops, cafés, and restaurants — rather than immediately defaulting to English — signals respect for the culture and consistently produces better service, warmer interactions, and occasionally offered hospitality (a complimentary dessert, a recommendation for a better restaurant nearby). Our Greek phrases guide covers everything you need.

The Greek Daily Rhythm

Greece operates on a specifically Mediterranean schedule that differs significantly from northern European norms. Understanding it prevents frustration:

Shops typically close 2-5pm for the siesta — particularly in summer and outside major tourist areas. Plan shopping in the morning or evening. Restaurants don’t fill until 9pm. Arriving at a good Athens or island restaurant at 7pm gets you immediate service but the restaurant at less than full energy. The best Greek dining experience happens after 9pm when the local population arrives. Cafés have unlimited sitting time — the concept of being asked to leave after finishing your drink does not exist in Greek café culture. Plan morning coffee to last as long as you want it to. Churches and monasteries close for the siesta and may have irregular hours — check before making a specific trip.

Monastery and Church Etiquette

Covered shoulders and knees for everyone at all churches and monasteries. No exceptions. No shorts, no sleeveless tops, no short skirts. Photography is usually permitted in exteriors but not inside the church proper — follow the signs. Silence inside the church. The monasteries of Meteora, the monastery of St John on Patmos, and the significant island monasteries are active religious communities. They admit visitors as a courtesy, not as an obligation. Treat the access accordingly.

Frequently Asked Questions

Do I need cash in Greece?

Yes — more than most visitors expect. Monasteries, smaller island tavernas, markets, beach sunbed rentals, and tips are all cash-only. Always carry €50-100. ATMs are available in all main towns but may be limited on smaller islands.

What is the best SIM card for Greece?

An Airalo eSIM is the most convenient option for compatible phones — activates on landing, covers all Greek islands without roaming charges. Alternatively, buy a Greek prepaid SIM (Cosmote, Vodafone, Wind) at Athens airport — €10-15 for 15-20GB, valid 30 days.

What shoes should I bring to Greece?

Comfortable closed-toe walking shoes for archaeological sites and city sightseeing (the Acropolis is particularly important — the marble is smooth and slopes). Reef shoes for rocky beaches and sea urchin protection. One smart-casual pair for evenings. Flip-flops for beaches only.

Do I need a visa for Greece?

EU/EEA citizens: no visa, ID card or passport sufficient. UK citizens: valid passport, no visa currently required for stays up to 90 days, but ETIAS is expected in late 2026. US, Australian, Canadian citizens: valid passport, no visa, 90 days maximum. Check current requirements for your nationality before booking.

Is Greece safe for tourists?

Yes — Greece is one of the safest countries in Europe for visitors. Standard urban precautions apply in Athens (watch bags in crowded tourist areas). The main safety risks are practical: heat in summer, rough sea conditions during the Meltemi, uneven surfaces at archaeological sites. Emergency number: 112.

What is the Meltemi wind and how does it affect my trip?

The Meltemi is a strong northerly Aegean wind blowing in episodes from mid-June to mid-September, peaking in July-August. It provides cooling relief in the heat but creates rough conditions on exposed Cyclades ferry crossings and can make some eastern-facing beaches uncomfortable. Fast catamarans are more affected than conventional ferries. Check weather before same-day boat trips. Full explanation in our island hopping guide.

What should I NOT bring to Greece?

A large suitcase if island hopping — carry-on only. High heels — cobblestones make them dangerous. Excessive clothing — Greek island laundry facilities are widely available and the heat means you wash and dry quickly. Expensive jewellery — practical risk at crowded tourist sites. Thick towels — most accommodation provides them, and beach towels are available cheaply on every island.
