Yes, the tap water on the island of Hvar, and throughout Croatia, is safe, clean, and healthy to drink. In 2026, Croatia continues to rank among the top European countries for water quality, meeting all stringent EU Drinking Water Directives. On Hvar, much of the water is supplied from the mainland via a sophisticated network of undersea pipelines, while some is sourced from local natural springs. The water is naturally filtered through the region's karst (limestone) geology, which can make it slightly "hard" (high in calcium), but it is perfectly safe for consumption. You will see locals and tourists alike filling reusable bottles at public stone fountains in Hvar Town and Stari Grad. Drinking tap water is not only safe but also environmentally responsible, as it reduces the massive amount of plastic waste generated by bottled water on the islands. If you are staying in a very old building, you may notice a slight metallic taste from old pipes, but the water remains potable.
