In total, 342 Italian beaches were given the FEE (Foundation for Environmental Education) certification - a huge increase of 49 compared to the previous year.
The environmental organization monitors the coast of 49 countries and awards 'blue flags' to beaches which meet a set of 32 criteria including clean water, ample facilities for visitors, safety, and environmental factors.
This makes them a useful indicator for bathers who are looking to spend a day in the sun but are unsure where to go.
Blue flag beaches can be found in 18 of Italy's 20 regions. The majority are dotted along the 7,600 kilometre coastline, though 13 entries can be found nestled by alpine lakes.
Liguria came out on top in the battle of the flags, with 27 prized beaches to its name, including two new entries this year, followed by Tuscany with 19 and Le Marche with 17.

Here's a closer look at three of the best spots to receive the blue flag this year.
Camogli, Liguria
This small town lies at the end of a famous trekking trail, from fishing village Portofino through hilltop church town San Rocco. The breathtaking views of Camogli are your reward, and two of the town's beaches earned blue flag status: the town's central beach, which was a new entry for this year, and San Fruttuoso, a scenic spot located in front of an abbey and only reachable on foot or by sea.
"Challenging trekking that requires a firm foot ... but the panorama, the smells, nature and the air will pay you back for the hard work!" wrote one visitor in a TripAdvisor review.
Sapri, Campania
This southern town was visited by the ancient poet Cicero, who called it "the little gem of the southern sea". Three of its beaches (Cammarelle, Lungomare di Sapri, San Giorgio) received the blue flag recognition this year.
It can be reached by train on the Salerno-Reggio Calabria line and is served by several long distance trains.
Lago di Piazze, Trentino
While most of the beauty spots can be found on Italy's coast, several lakes received the blue flag this year, including the Lago di Piazze in Bedollo, Trentino.
Measuring 1,200 by 300 metres on average, the lake is surrounded by beaches and grassy slopes that make it an ideal summer bathing spot.
