Yes, the tap water in Positano and throughout the Amalfi Coast is safe to drink and generally of very high quality. The water is sourced from mountain springs in the Lattari Mountains and undergoes rigorous municipal testing to meet EU standards. Many travelers find the water in Positano to be cold, crisp, and refreshing, similar to mineral water. Throughout the town, you will also find public stone fountains, known as nasoni, where you can refill your reusable water bottle for free with the same high-quality spring water. While the water is safe, it does have a high mineral content (hard water), which some people with very sensitive stomachs might find slightly different from their home supply. In 2026, it is a "pro" sustainability tip to skip the expensive €3-€5 plastic bottles of water sold in the tourist shops and use the local tap water instead; it saves money and helps reduce the significant plastic waste issue that affects the delicate coastal environment of the Amalfi region.
