Yes, you can drink tap water in Athens, as city supplies meet EU safety standards, though some visitors still prefer bottled water for taste.
Athens is hot, busy, and full of steep streets, so staying hydrated matters more than almost anything on your packing list. At some point you look at the hotel sink and ask the obvious question: can you drink tap water in athens? Local friends may say yes, other travelers swear by bottled water only, and the mixed messages can feel confusing when you just want a clear answer.
The short version is reassuring. Municipal tap water in Athens is treated, monitored, and classed as safe for drinking under European rules. That said, taste, old building pipes, and sensitive stomachs can still influence what feels comfortable for you. The guide below walks through how Athens water is treated, when tap water is fine, when bottled water makes sense, and the small daily habits that keep you well on your trip.

Can You Drink Tap Water In Athens?
The city’s tap water is supplied and monitored by EYDAP, which runs large treatment plants, accredited laboratories, and a wide monitoring network. The company states that water samples from treatment plants and the distribution system meet Greek legal standards for water intended for human use, which reflect European Union rules on microbiological and chemical safety. Public reports from these EYDAP water quality checks show consistent compliance with those requirements.:contentReference[oaicite:0]{index=0}
On paper and in daily life, that means the answer to “can you drink tap water in athens?” is yes for the vast majority of visitors. Many residents fill reusable bottles at home, drink straight from the kitchen tap, and give the same water to their children. Travel writers and tour companies that specialize in Greece also describe Athens tap water as safe for drinking, with the main complaints linked to taste rather than illness.:contentReference[oaicite:1]{index=1}
Still, “safe” in a regulatory sense does not always match how every stomach reacts. Any change in diet, microbes, or routine can unsettle digestion on the road. Medical sources point out that traveler’s diarrhea and other gut upsets are common during international trips, even when local tap water meets standards, simply because the mix of bacteria differs from what your body knows at home.:contentReference[oaicite:2]{index=2}
Drinking Tap Water In Athens Safely As A Visitor
Once you know that Athens water is treated and monitored, the next step is working out what feels comfortable for your own health. A few habits make it much easier to drink the tap water with confidence or to switch to bottled water in a smart way if you prefer.
Know Where The Water Comes From
Athens does not draw drinking water from small urban wells. The network pulls from large reservoirs such as Marathon, Yliki, Mornos, and Evinos, then pipes that water to treatment plants on the edge of the city. From there, the network carries treated water through thousands of kilometers of mains to homes, hotels, and businesses.:contentReference[oaicite:3]{index=3}
At each stage, samples are checked in chemical and microbiological laboratories. Greek regulations require that results for water intended for human use meet limit values for microbes, nitrates, heavy metals, and other indicators. In practical terms, this means the glass that comes out of a typical Athens kitchen tap is closer to what you would expect in many other European capitals than to small rural supplies in countries with limited infrastructure.
Health agencies still remind travelers that no system reaches zero risk. Global guidance on food and water safety recommends paying attention to local advice, watching for emergency notices, and having a backup plan such as bottled water or reliable filters when visiting places with uncertain supplies. The CDC water safety advice outlines common sense habits that apply anywhere in the world, including Greece.:contentReference[oaicite:4]{index=4}
Taste, Chlorine, And Sensitive Stomachs
Many travelers say the first sip of Athens tap water tastes different from what they are used to at home. The most common comment is a noticeable chlorine note. That chlorine is there on purpose to keep microbes under control as water travels through the network.:contentReference[oaicite:5]{index=5}
If the taste bothers you, a few small tricks help a lot. Fill a bottle and let it sit open in the fridge for a short while so the chlorine smell can fade. Run the cold tap for a short time before pouring, especially first thing in the morning. A simple filter jug or bottle can also soften the flavor, though it is not required for safety in normal conditions.
Some visitors feel that their stomach reacts to even small differences in water. If you have a history of digestive issues, you may choose a middle path: drink tap water in Athens for brushing teeth and making tea or coffee, then stick to bottled water for large glasses on an empty stomach. Pay attention to how you feel over the first day or two and adjust from there.
Older Buildings And Apartment Pipes
Water quality at the treatment plant is one thing; water that has passed through old building pipes or rooftop tanks can be another story. Older apartment blocks in Athens may still have internal plumbing that adds a slight metallic taste, or they may rely on storage tanks that do not get cleaned as often as they should.
Simple habits reduce that risk. Use the cold tap for drinking and cooking, not the hot tap. Let the water run for a short time if a faucet has not been used for several hours. If the water comes out brown, cloudy, or with visible particles, skip that tap and talk to your host or reception desk. They may already know about a temporary maintenance issue on the street and can point you to a safer source inside the same building.
When you stay in modern hotels with recent plumbing, these issues are less likely. Larger chains and well-reviewed city hotels often highlight their water treatment steps or provide both a kettle and clear instructions on whether tap water is drinkable in rooms. When in doubt, a quick question at reception brings a direct answer for that specific property.
Tap Water Around Athens And The Greek Islands
One reason the question “can you drink tap water in athens?” comes up so often is that Greece is not uniform. Conditions in the capital differ from those on smaller islands and rural villages. National and regional travel sources agree that tap water is generally safe in major cities such as Athens and Thessaloniki, while advice is more cautious for many islands.:contentReference[oaicite:6]{index=6}
Island supplies can rely on desalination plants, shipped-in water, or small local sources with limited storage. In some places the water tastes brackish, and local authorities themselves tell guests not to drink it but to use it only for washing. That is why hotels on islands often place bottled water in rooms on arrival and post clear notes in bathrooms.
When you leave Athens for day trips or island hops, check signs in your accommodation and ask staff specifically about tap water for drinking, ice, and teeth brushing. If staff say locals drink from the tap without concern, you can usually treat that water in the same way as you would in the capital. If they advise bottled water, follow that lead and avoid refilling bottles from bathroom sinks in that location.
When Bottled Or Filtered Water Makes Sense
Bottled water is not strictly necessary in Athens for most visitors, yet there are moments when choosing sealed bottles or extra filtration is a smart move. Think through your route and personal health, then match the option to the situation.
| Situation | Tap Water Use | Recommended Choice |
|---|---|---|
| Short city break in central Athens | Safe to drink in most hotels and apartments | Refill a reusable bottle from the tap once you trust the building supply |
| Day trip to a nearby island | Quality varies by island and village | Ask local staff; carry a bottle of water from Athens as backup |
| Stay on a small or arid island | Sometimes suitable only for washing and brushing teeth | Buy sealed bottled water for drinking and cold drinks with ice |
| History of gut conditions | Change in microbes may trigger symptoms | Use tap water in Athens with care or stick to bottled water if you feel uneasy |
| Travel with infants or frail relatives | Extra caution often feels better for caregivers | Use bottled or boiled water for drinking and baby formula unless your doctor says otherwise |
| Long hike outside the city | Natural streams and village taps are not guaranteed safe | Carry enough bottled water or use trusted filters rather than drinking from unknown sources |
| Temporary local advisory | Leaks, pipe repairs, or heavy rain can prompt notices | Follow municipal instructions until the network is cleared again |
If you already own a quality travel filter bottle, bringing it to Athens can bridge the gap between full trust in the tap and constant bottled purchases. A filter designed for urban travel helps mainly with taste and some residual particles. In remote hiking areas, where surface water is the only option, follow international advice on boiling or filtering water from natural sources rather than drinking directly.:contentReference[oaicite:7]{index=7}
Practical Tips For Drinking Water In Athens
Once you decide how you feel about tap water, a few local habits make day-to-day life in the city easier. These tips save money, cut plastic waste, and still keep comfort and health at the front of the plan.
Using Public Fountains And Refill Points
Across central Athens you will see small public fountains, often near squares or parks. In areas served by the main network these usually run on the same treated water that reaches homes. Many locals refill bottles here during walks or commutes. Still, look for any nearby signage; if the water is not meant for drinking, the city often posts a note or symbols to say so.
Your safest bet is to refill at your hotel, a known cafe, or a coworking space, then top up only from fountains that residents clearly use for drinking. Avoid taps that are rusty, that run through improvised hoses, or that sit next to roadworks or construction sites.
Ordering Water In Cafes And Restaurants
In Athens, many restaurants bring bottled still water to the table by default and add it to the bill. Tap water is safe in most parts of the city, so if you prefer not to pay for bottles at every meal you can ask whether they can serve tap water instead. Some places are happy to bring a jug of tap water; others stick to bottled only, which is their right.
Ice in drinks in the capital generally comes from treated tap water, frozen in commercial ice machines. In well-run venues, locals drink iced soft drinks and cocktails with no hesitation. If you receive ice in a village or on an island where tap water is not suitable, treat that drink in the same way as the local advice for drinking water in that location.
Staying Hydrated In Summer Heat
Summer heat in Athens can be fierce, especially on marble streets and archaeological sites with little shade. Plan to drink water steadily through the day rather than waiting until you feel thirsty. Start with a full bottle at your accommodation, refill during meal breaks, and keep an eye on signs of dehydration such as dark urine or a dry mouth.
Alcohol and strong coffee are part of Greek holidays for many visitors, but both can leave you feeling worse if you forget to balance them with water. A simple routine works well: one glass of water for every alcoholic drink, and a bottle of water in your bag whenever you leave the room. Whether that bottle is filled from the Athens tap or bought at the kiosk on the corner, the goal is the same: steady hydration so you can enjoy the city rather than search for pharmacies.
