💧 Drinking water on the Greek islands — what to know
Wondering if the water on the Greek islands is drinkable? The short answer: it depends on the island. In some places, tap water is safe to drink, while in others you should stick to bottled water. Here’s where you can refill your bottle — and where it’s better to buy.
🚰 Where tap water is drinkable
In Athens, Naxos, Antiparos and Amorgos, tap water is considered safe, although the taste may vary. In contrast, islands like Koufonisia, Mykonos, Santorini and Ios rely on desalination, so it’s best to use bottled water for drinking. You can safely use tap water for showers or washing fruit.
On islands such as Astypalaia and Serifos, quality has improved recently, but locals still tend to buy bottled water — especially in August when demand peaks.
♻️ Where to refill your bottle
Most islands have public fountains with potable water, usually near main squares, churches or town halls. In cafés or beach bars, you can politely ask to refill your bottle, people are generally happy to help.

🧃 If it’s not drinkable, what to do
On islands where tap water isn’t drinkable, go for large bottled containers (5–10L) to reduce plastic waste. Alternatively, use a portable water filter or filtering jug, especially if you stay several days in the same accommodation.
If you have a sensitive stomach, avoid ice in drinks and prefer sealed bottles. And for extra peace of mind, always travel with reliable travel insurance .
