Barcelona's metropolitan beaches extend along 42km of coastline, for a total of 42 beaches. These beaches receive more than 11 million visitors every year. They are natural ecosystems of biodiversity, some of which are protected at European level under the Natura 2000 network, such as Gavà, Viladecans and El Prat de Llogregat.
The 2024 bathing season on the beaches of the Barcelona Metropolitan Area is marked by the start of the project to implement the ColorADD system on the sea state flags at 25 beach entrances in this district, with the aim of spreading this implementation to all beach entrances in the coming bathing seasons.

This work has been carried out over the last two years in close partnership with ADEAC, which promotes this good practice of integrating people with color blindness into all of Spain's Blue Flag beaches.

It is worth remembering that, in the heart of Barcelona, we have the first hospital with ColorADD implementation in Spain - Hospital de la Santa Creu y Sant Pau - and that this is another step towards ensuring that residents and visitors to the Catalan capital can have ever closer contact with the color identification code for the color blind, which serves more than 350 million people in the world who cannot identify colors.
