When you think of Croatia, crystal-clear seas, charming old towns and sun-drenched islands come to mind. But what about the water from the tap? Is it really safe to drink without concern?
The answer is more complicated than you might think.
Officially, the answer is yes. Croatia complies with EU directives and the water is considered safe. But as is so often the case, the reality depends on the location, infrastructure and circumstances. In some regions, people drink it straight from the tap. In others, it is better left alone.
Read on to find out where you can fill your glass without concern – and where it is better used only for brushing your teeth...
What it really depends on
1. Infrastructure is crucial
The problem is often not the water itself, but the pipes. In older holiday accommodation or on islands where maintenance is limited, rusty pipes, limescale and biofilms can affect its quality.
2. Cisterns pose a risk
On many smaller islands or in remote areas (for example Vis, Lastovo or parts of Krk), water is stored in cisterns. This “collected” water is sometimes treated with chlorine – and sometimes it is not. Drinking water? Only at your own risk.

3. Summer puts pressure on the network
During the high season, consumption and temperatures rise sharply. Older networks may struggle with the demand. The water can occasionally “smell of fish” overnight or appear cloudy. It is usually harmless, but not appetising.
4. Water in boat tanks can become stale
Anyone who lives or holidays on a sailing boat knows the problem: water from the tanks tastes stale, metallic or even foul. The only solutions are reverse osmosis or boiling.
What locals and experienced visitors do:
- In the city: Tap water? Of course.
- In a village or on an island: Test it first, then drink it.
- If in doubt: Boil it or buy water from the supermarket.
- Bonus tip: Many Croatians collect their water directly from mountain springs. It does not get any fresher than that.
Conclusion:
Croatian tap water is drinkable in many regions – sometimes it is even better than the water in Germany. But anyone who wants to be certain should trust their nose, take a clear look into the glass and use common sense.
