Athens Travel Tips: What to Know Before You Visit

Most guides to Athens lead with the sights. This one skips them, because the Acropolis, Plaka and the rest of the historic centre are covered in our layover guide to the Acropolis and Plaka. What follows is the practical layer underneath the sightseeing: money, language, dress codes, opening-day quirks, and the small logistics that first-time visitors either don’t think to ask about or only discover after landing. None of it is complicated, but knowing it before you arrive saves a genuinely annoying moment or two, the kind that don’t ruin a trip alone but add up if you hit three of them in one day.

Money, cards and tipping

Greece uses the Euro. Cards are widely accepted across Athens, including hotels, restaurants, museums and most shops, but small tavernas, kiosks and street vendors sometimes prefer cash, so carry some for smaller purchases rather than assuming a card always works. If your bank charges foreign-transaction fees, check before you travel rather than finding out from a statement afterwards.

Tipping is appreciated rather than obligatory. Rounding up the bill or adding 5 to 10% at restaurants is normal when service has been good, not a rule anyone enforces. Nobody will chase you for skipping it and nobody will be surprised if you do it. The same light touch covers taxi drivers and guides: round up rather than calculating a precise percentage, and don’t feel obliged at counter-service places where you order and pay upfront.

Language

Greek is the official language, and English is widely spoken in tourist areas. Hotel staff, restaurant servers and shop assistants in central Athens generally handle it comfortably, and most menus and signage in the areas visitors actually use are bilingual. You won’t need more than that to get around, but a few Greek words go a long way and tend to be met more warmly than English alone. A kalimera (good morning) in a shop, an efharisto (thank you) at a taverna. It costs nothing to try, and Athenians generally appreciate the effort even when your accent gives you away immediately.

When to visit

April to June and September to October are the sweet spots: mild temperatures, manageable crowds, and days long enough to cover the city’s outdoor sites without racing the clock or the heat.

July and August regularly exceed 35 °C, and it is the kind of heat that changes how you plan a day rather than just how you dress for it. Exposed stone sites with no shade, the Acropolis above all, turn from a pleasant walk into something you want to get through quickly. If you are visiting in peak summer, build the schedule around early morning. Hit the big shade-free sites first thing while the temperature is still bearable, and treat early afternoon as a break rather than sightseeing time, the way locals do.

Dress codes and site etiquette

Most archaeological sites in Athens don’t enforce a dress code beyond common sense, but monasteries and churches do. Covered shoulders and knees are expected, and Hosios Loukas, the Byzantine monastery on the Delphi route, actively enforces this rather than posting it as a polite suggestion. A light scarf or spare layer in your bag covers an unplanned stop at a church without having to plan your whole outfit around the possibility.

At ancient sites more broadly, skip flash photography where it is posted (a rule at some museums and interior spaces rather than a universal one) and don’t touch the marble, however tempting a 2,500-year-old column is to run a hand along. Stone that has survived millennia wears from contact more than most visitors expect, and it is one of the easier ways to be that tourist without meaning any harm.

Opening days: the Monday problem

Many Greek museums and some archaeological sites close one day a week, often Monday or Tuesday, and opening hours tend to shorten outside summer. It is a pattern worth knowing about but not one worth building a fixed rule around. The exact closure day and off-season hours vary site to site, and a schedule that holds for one museum won’t necessarily hold for the next on your list. Check the specific site for your date before building a day around it.

Safety and health

Athens is a generally safe city for visitors and most trips pass without incident. The main thing to watch is the same as in any major city with heavy tourist traffic. Pickpockets work crowded areas and Metro Line 3, the line most visitors use to and from the airport, and they warrant the same caution you would use anywhere else: bag zipped and in front of you, wallet out of a back pocket, a bit more attention in a packed carriage than you would otherwise bother with. None of this is specific to Athens. It is the low-level awareness worth carrying through any busy transit system in a city you don’t know well.

For emergencies, the pan-European number 112 works anywhere in Greece and connects you to police, ambulance or fire. There is also a dedicated tourist police line, 171, worth saving in your phone before you land. Confirm it is still current before relying on it. Tap water in Athens is safe to drink, so a refillable bottle works throughout the trip without buying bottled water at every stop.

Getting from the airport

Athens airport connects to the city by metro, express bus, taxi and private pickup, and which one makes sense depends on your luggage, your timing and how tight the connection is. For the options, the trade-offs between them, and what actually fits your connection, see the Athens layover guide, which covers airport transport in full.

What to pack

Walking shoes matter more in Athens than in most cities. Ancient marble underfoot gets polished smooth by decades of foot traffic and turns genuinely slick, at the Acropolis especially, so this is not a place for sandals if you are covering any real distance.

Beyond footwear: sun protection for exposed sites with little shade, a refillable water bottle, a Type C/F power adapter for anything you need to charge, and a light layer for museum interiors, where the air conditioning runs noticeably cold against the heat outside. None of it is exotic. It is the difference between a comfortable day and one spent distracted by something you forgot.

Planning your time

Once the logistics above are sorted, the real question is how to spend the day. Our 8-hour layover guide shows how the Acropolis, its museum and Plaka fit into a short visit, with or without a private driver. If your connection is tight and you would rather not manage timing, tickets and navigation yourself, the private Athens tour from €119 per person handles pickup, luggage and the schedule. The practical questions on this page become someone else’s job and the only thing left to do is look.
