Athens Travel Tips: What to Know Before You Visit

Most guides to Athens lead with the sights. This one skips them — you’ll find the Acropolis, Plaka and the rest of the historic centre covered in our one-day itinerary instead. What follows here 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 on their own, but add up if you hit three or four of them in the same day.

Money, cards and tipping

Greece uses the Euro (€). Cards are widely accepted across Athens — hotels, restaurants, museums and most shops all take them without issue — but small tavernas, kiosks and street vendors sometimes prefer cash, so it’s worth carrying some for smaller purchases rather than assuming a card will always work. If your bank charges foreign-transaction fees, it’s worth checking before you travel rather than finding out from a statement afterward.

Tipping is appreciated rather than obligatory: rounding up the bill or adding roughly 5–10% at restaurants is normal practice when service has been good, not a rule anyone will enforce or expect. Nobody will chase you down for skipping it, and nobody will be surprised if you do it. The same light-touch approach covers taxi drivers and guides — round up rather than calculate a precise percentage, and don’t feel obligated to tip 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 spend time in 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 with a warmer response 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–June and September–October are the sweet spots — mild temperatures, manageable crowds, and long enough days to cover the city’s outdoor sites comfortably without racing the clock or the heat. July and August regularly exceed 35 °C, and it’s 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, like the Acropolis, turn from a pleasant walk into something you want to get through quickly. If you’re visiting in peak summer, build your schedule around the early morning — hit the big, shade-free sites first thing while the temperature is still bearable, and treat the early afternoon as a break rather than sightseeing time, the way locals do.

Dress codes and site etiquette

Most archaeological sites in Athens itself 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, is one where this is actively enforced rather than just posted as a polite suggestion. Carrying a light scarf or a spare layer in your bag covers you for an unplanned stop at a church along the way, without having to plan your whole outfit around the possibility.

At ancient sites more broadly, skip the flash photography where it’s posted — a rule at some museums and interior spaces, not 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’s survived millennia wears from contact more than most visitors expect, and it’s one of the easier ways to be that tourist without meaning any harm at all.

Opening days: the Monday problem

Many Greek museums and some archaeological sites close for one day a week, often Monday or Tuesday, and opening hours tend to shorten outside the summer season. It’s a pattern worth knowing exists, but not one worth building a fixed rule around — the exact closure day and off-season hours vary from site to site, and a schedule that holds for one museum won’t necessarily hold for the next one on your list. The safest approach is simple: check the specific site for your date before you build a day around it, rather than assuming a pattern you read somewhere applies to the place you’re actually planning to visit.

Safety and health

Athens is a generally safe city for visitors, and most trips pass without incident. The main thing to watch for is the same as any major city with heavy tourist traffic: pickpockets in crowded areas and on Metro Line 3, the line most visitors use to and from the airport, warrant the same normal caution you’d use anywhere else — bag zipped and kept in front of you, wallet not in a back pocket, a bit more attention in a packed train carriage than you’d otherwise bother with. None of this is specific to Athens; it’s the same low-level awareness worth carrying through any busy transit system in any 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’s also a dedicated tourist police line, 171, worth saving in your phone before you land (confirm it’s still current before relying on it). Tap water in Athens is safe to drink, so a refillable bottle works fine throughout the trip without needing to buy bottled water at every stop — one less thing to carry or budget for across a multi-day stay.

Getting from the airport

Athens airport connects to the city by metro, an express bus, taxi, and private pickup, and which one makes sense depends on your luggage, timing and how tight your connection is. For the transport 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 isn’t a place to attempt in sandals if you’re covering any real distance. Beyond footwear: sun protection (hat, sunscreen, sunglasses) for exposed sites with little to no shade, a refillable water bottle you can top up rather than buy bottled water for, a Type C/F power adapter for anything you need to charge, and a light layer for museum interiors, where the air-conditioning tends to run noticeably cold against the heat outside. None of it is exotic — it’s the difference between a comfortable day and one spent distracted by something you forgot.

Planning your time

Once the logistics above are sorted, the actual question is how to spend the day. Our one-day Athens itinerary lays out a sequenced route through the Acropolis, Plaka and the rest of the historic centre in the order that avoids crowds and dead time, with a shorter version built specifically for layovers. If your connection is tight and you’d rather not manage timing, tickets and navigation yourself on top of everything else, the private Athens tour from €119 per person handles pickup, luggage and the schedule for you — the practical questions on this page become someone else’s job, and the only thing left for you to do is look.
