Sitges has managed to consolidate the 9 blue flags for the beaches of the municipality. These 9 distinctions keep the town as the leading municipality in Catalonia in blue flags. Specifically, the beaches that will have a blue flag for this season are Les Botigues, Garraf, Aiguadolç, Balmins, San Sebastián, La Ribera, L'Estanyol, La Barra and Terramar. In addition to the recognition in the form of blue flags, the beaches of Sitges adhere to the Biosphere certification and two Sitges marinas also obtain the blue flag: Port Ginesta and Port de Garraf.

The distinction, awarded to 9 of the 20 urban beaches in the municipality, rewards sustainability, water quality, safety, attention to people with functional diversity and the complementary or educational offer that takes place in these spaces. The Sitges beach rescue service has deserved this highest recognition, but also having access to the beaches for people with reduced mobility and services for this group, from being able to swim in an amphibious chair to being able to have a shaded area.
