Yes, it is perfectly safe to drink the tap water in the towns surrounding Lake Como, such as Como, Bellagio, and Varenna. The water in the Lombardy region of Italy is highly regulated and undergoes rigorous testing to meet both Italian and European Union safety standards. In 2026, many of the local municipalities draw their water from Alpine springs or deep wells, which provide high-quality, mineral-rich water. You will also see many public drinking fountains (fontanelle) throughout the villages that provide cold, fresh water for free—a great way for 2026 tourists to refill reusable bottles and reduce plastic waste. While some visitors might find the mineral content (hardness) slightly different from what they are used to at home, it is bacteriologically safe and often tastes better than bottled water. The only exception would be if you see a sign specifically marked "Acqua non potabile" (Non-potable water), which is sometimes found at decorative fountains or in very old, unrestored buildings.
