Casa dell'Acqua

Casa dell'Acqua is one of Naples' public water refill stations where you can fill up your bottle with chilled, still, or sparkling purified water for just a few cents — or sometimes free. Once you notice your first one, you'll start spotting them all over the city — tucked near piazzas, metro stops, and parks. It's a genuinely smart local hack for staying hydrated without buying endless plastic bottles.
