Can You Drink the Tap Water in Ljubljana?
Tap water in Ljubljana is safe to drink and is among the finest in Europe, sourced from clean Alpine aquifers and served directly from the tap throughout the city.
Complete Drinking Water Safety Information for Ljubljana
Ljubljana's tap water is exceptional — widely regarded as among the finest in Europe — and is completely safe to drink directly from the tap throughout the city. The water is sourced from clean underground aquifers fed by the Julian Alps and the Kamnik-Savinja Alps, and is distributed by Javno podjetje Vodovod-Kanalizacija (JP VO-KA), Ljubljana's municipal water utility. The water requires minimal treatment due to the purity of its Alpine groundwater sources, and it meets and exceeds EU drinking water standards throughout the supply area.
Ljubljana has made its exceptional tap water a point of civic pride. The city operates a network of public drinking water fountains — marked pitna voda (drinking water) — distributed throughout the pedestrianised old town and city centre, providing free high-quality drinking water to residents and visitors. In 2017, Ljubljana became the first European capital to commit to providing free public drinking water citywide as part of its Zero Waste and environmental sustainability strategy. Refilling a reusable bottle at any of these fountains is actively encouraged and widely practised.
The old town along the Ljubljanica river, the hilltop Ljubljana Castle, Metelkova, and the broader city centre all sit within the same excellent municipal supply area. Restaurants, cafes, and hotels throughout Ljubljana serve the same high-quality tap water. Visitors will find that coffee, which requires excellent water, is of uniformly high quality throughout Ljubljana — a direct benefit of the city's outstanding water supply.
Day trips from Ljubljana to Lake Bled, the Soča Valley, and Postojna Cave are popular and the water quality throughout the broader Ljubljana region and Gorenjska is equally excellent. Slovenia as a whole has the highest per-capita freshwater resources in the EU, and this natural abundance is reflected in the quality of water available at every tap in Ljubljana and its surroundings.
Bottled water is available throughout Ljubljana but is genuinely unnecessary. Locals and environmentally conscious visitors use refillable bottles and the city's public fountains. If you do purchase bottled water, Slovenian mineral water brand Donat Mg — sourced from Rogaška Slatina in eastern Slovenia — is one of the world's most mineral-rich natural waters and worth trying as a local specialty.

Bottled water is available throughout Ljubljana at supermarkets, kiosks, and convenience stores, but is largely unnecessary given the city's excellent tap water.

If you want to try a local specialty, Donat Mg — a natural mineral water from Rogaška Slatina with one of the highest magnesium contents of any natural mineral water in the world — is widely available and distinctively flavoured. Standard bottled water prices are €0.30–€0.70 per 1.5-litre bottle in supermarkets.
