Yes, in 2026, the tap water in the Lake Como region is perfectly safe to drink and meets the high safety standards set by the European Union. The water is primarily sourced from deep underground aquifers and natural mountain springs, which are then treated and strictly monitored by local health authorities. While it is safe, the water in Northern Italy is often "hard," meaning it has a high mineral content (calcium and magnesium). This can give the water a slightly "chalky" taste that might differ from what you are used to at home, but it is not harmful. Many towns around the lake, such as Bellagio and Varenna, even have public fountains where you can refill your bottle with chilled, fresh water for free. In 2026, most restaurants will still try to sell you bottled mineral water (acqua minerale) as part of the dining tradition, but you can always ask for "acqua del rubinetto" (tap water) if you prefer. Using tap water is not only safe but also the most environmentally friendly choice, helping to reduce the plastic waste that can impact the lake's delicate ecosystem.
