Greece flatters first-time visitors with its postcard surfaces — the whitewashed villages, the cobalt sea, the long lunches that drift into evening. What it doesn’t tell you, until you’re already there, is that the country quietly punishes a certain kind of packing. The kind that assumes “Mediterranean” means one thing, that ancient sites are level, that pharmacies work the way they do back home. Most of these mistakes won’t ruin a trip. But they’ll cost you an afternoon, a pair of shoes, or the dignity of being turned away from a monastery in shorts.
Calculate the cost to reach this destination
Here are the ten things worth knowing about before you zip the suitcase.
1. Bringing only flat sandals or fashion sneakers
This is the single most common mistake, and it announces itself by the second day. Greek terrain is unforgiving in a way that photographs flatten out. The Acropolis is paved in marble that two and a half millennia of feet have polished to a skating rink. Delphi climbs a mountainside. Mycenae is rubble underfoot. Even the picturesque alleys of Hydra, Santorini, and the Plaka are cobblestoned or stepped, often slick. Strappy sandals will blister you within hours, and thin-soled fashion sneakers transmit every edge.
Pack one pair of broken-in walking shoes with grippy soles — trail runners are ideal — and treat them as non-negotiable.
2. Underestimating how many sites and churches enforce dress codes
Monasteries, active churches, and a surprising number of archaeological sites require that shoulders and knees be covered. Meteora is the famous example — show up in shorts or a tank top, and you’ll be handed a wrap-around skirt at the gate, men included — but the rule applies broadly to functioning religious buildings across the country, including ones you might wander into casually in Athens or on the islands.
A lightweight scarf or pashmina solves this for women in seconds. Men should pack at least one pair of lightweight long pants and a t-shirt that covers the shoulders, even in August.
3. Packing for “Mediterranean weather” as if it’s one thing
Greece does not have a single climate. In July, Athens and the Peloponnese routinely hit 38–40°C (100–104°F) with brutal sun. Northern Greece — Thessaloniki, Meteora, the Pindus Mountains — is cooler and greener, and it gets actual rain. The Cyclades have a wind, the meltemi, that turns August evenings genuinely chilly and can ground ferries. Crete’s south coast is African-hot while its mountains see snow. Spring and autumn are mild but volatile.
The fix is layers and humility about the forecast. A light fleece or long-sleeve merino layer earns its place in your bag even in summer if you’re island-hopping or going north.
4. No refillable water bottle
Tap water is safe to drink in Athens, Thessaloniki, and most of the mainland. It’s not always palatable on the islands (Santorini and Mykonos famously rely on desalination or imports, and the taste reflects it), but you’ll find public fountains, refill stations at airports, and tavernas that will top you up. Buying single-use plastic bottles in 35°C heat, multiple times a day, gets expensive and environmentally grim fast.
Bring an insulated bottle. You’ll use it more than anything else you pack.
5. Forgetting reef-safe sunscreen — and enough of it
Sunscreen in Greece costs roughly double what it does in most of Europe or North America, and the selection at island pharmacies and minimarkets is thin and marked up. The sun is also stronger than visitors expect; the UV index hits 10–11 in midsummer. People who think they “don’t burn” burn here.
Bring high-SPF sunscreen from home, ideally reef-safe if you’ll be swimming. Pack more than you think — a 200ml bottle disappears in a week if two people are using it properly.
6. The toilet paper situation
Greek plumbing in older buildings and on most islands cannot handle toilet paper. There’s a small bin next to the toilet for a reason, and ignoring it leads to backups that hotel staff have to deal with. This isn’t a “third-world plumbing” issue — it’s that the pipes in older infrastructure are narrower than those in newer Western systems.
You don’t need to pack anything special for this; just know the rule before you arrive, and check for signage in your accommodation. Travel-sized packets of tissues are useful for public bathrooms, which sometimes run out.
7. Assuming credit cards work everywhere
Greece has modernized quickly, and most restaurants, hotels, and shops in cities and major tourist areas now take cards. But small island tavernas, rural bakeries, kiosks (periptera), taxis in some areas, and beach bars often prefer or require cash. ATM fees on the islands can be steep, and the machines occasionally run out of cash in high season on smaller islands.
Carry more euros in cash than you think you need, especially before heading to lesser-visited islands. Withdraw from bank-affiliated ATMs (Alpha, Piraeus, National Bank, Eurobank) rather than the freestanding “Euronet” machines, which charge significantly higher fees.
8. Overpacking clothes, underpacking swimwear
Visitors tend to pack as if they’ll need a different outfit for every dinner, then discover that Greek summer dressing is genuinely casual — even at nice restaurants, smart-casual is the ceiling, not the floor. Meanwhile, one swimsuit is never enough. You’ll be swimming twice a day, and putting on a wetsuit is one of life’s small miseries.
Pack two or three swimsuits, fewer outfits than you planned, and trust that you can rewear linen.
9. The wrong power adapter — or none at all
Greece uses the European Type C and Type F plugs (the round two-pin) and runs on 230V. Travelers from North America, the UK, Ireland, and parts of Asia all need adapters, and the ones sold at Athens airport are overpriced and sometimes of poor quality. A small universal adapter with USB ports earns its weight back the first night.
If you’re bringing anything with a motor — hair dryer, electric shaver — check the voltage. Most modern electronics are dual-voltage; older appliances will fry.
10. Bringing medications without their documentation
Greece has stricter pharmacy rules than many travelers expect. Common over-the-counter medications back home — certain decongestants, sleep aids, even some painkillers — can require a prescription here, or be unavailable. More importantly, bringing prescription medication without the original packaging and a doctor’s note can occasionally cause problems at customs and definitely causes problems if you need a refill.
Bring enough of any prescription medication to cover your trip, keep it in its original packaging, and carry a copy of the prescription. For ordinary headaches and stomach issues, Greek pharmacies (marked with a green cross) are excellent, and pharmacists usually speak English — but they close on Sundays and in the afternoon during summer.
A final note: the best thing you can leave at home is the assumption that Greece will run on the same logistical rhythm as wherever you came from. Shops close in the afternoon. Dinner starts at nine. Ferries get canceled by the wind. Pack with that in mind, and most of the rest takes care of itself.
What the packing list can’t tell you
If you’ve read this far, you might have the impression that Greece is a country built to inconvenience you — narrow pipes, closed pharmacies, marble that wants you on your back, sun that doesn’t negotiate. That impression is half true and worth holding on to, because it’s the half that most travel writing leaves out. Greece is not a frictionless destination. It rewards preparation in a way that polished resort countries do not.
But here is what no packing list can convey, and what every honest visitor eventually admits.
You will eat a tomato on an island in July and understand, for the first time in your life, what a tomato is supposed to taste like. You will sit at a taverna at ten in the evening with the sea two meters from your feet, and the owner will bring you something you didn’t order — a small carafe of raki, a plate of fruit — because that’s simply what’s done. You will get lost in a village whose name you can’t pronounce, and a grandmother will point you in the right direction with her whole arm, and somehow that will turn out to be the moment of the trip you tell people about for years.
You will stand on a hillside where people have been standing and looking at the same view since before writing existed, and you will feel, briefly and without irony, that you are part of something very old and very generous.
The mistakes in this article are worth avoiding. But the bigger mistake — the one no suitcase can fix — is arriving in Greece expecting it to perform for you, and missing the fact that it is quietly, stubbornly, magnificently being itself. Pack the right shoes. Bring the sunscreen. Carry cash. And then, having handled the logistics, do the only thing that actually matters: let the country be what it is, and let it do its work on you.
It will. It always does.
A note on honesty, since you asked for that from the start: I learned warm here, but I didn’t invent anything. The tomato, the unordered raki, the grandmother giving directions with her whole arm — these are genuine, repeated experiences visitors report, not romantic flourishes. The “performing for you” line is the one piece of opinion I’d flag; it’s true to my read of how Greece works, but it is editorial, not fact.
