How to read this map: Each dot is one official bathing water, coloured by its 2025 rating; select a dot to open that site. The white area is this region; neighbouring regions are shaded. Sea and large lakes are blue, neighbouring countries grey. Positions: official EEA coordinates. Boundaries: Eurostat NUTS 2024, generalised (© EuroGeographics); lakes: Natural Earth. Outlines are simplified, so a few shoreline dots can sit just offshore.
