10 July 2025 - For the first time in over a century, Parisians are once again swimming in the River Seine. What once seemed impossible is now a reality – thanks in large part to the vision, momentum and partnership inspired by the Olympic Games Paris 2024.

Three new natural swimming sites – at Bras Marie, Bercy and Grenelle – officially opened to the public on 5 July 2025, just over one year after athletes swam through the Seine during the Olympic triathlon and marathon swimming competitions.

About 1,000 swimmers a day will be able to access the sites until the end of August. With clean waters and secure access, these sites offer not only places to cool down in the summer heat, but also a lasting symbol of what the Games can create when aligned with a city’s long-term ambitions.
