Just a few years ago, the idea sounded almost like a nostalgic postcard from another era: people swimming in the Seine in the heart of Paris. By summer 2026, this image will actually be part of everyday life. Eight free and supervised swimming areas along the Seine and the Marne will open their access to the public, marking another step in the recovery of rivers as living spaces.
Special attention is given to the three new swimming areas within Paris. They combine leisure, sport, and urban life in a way that was difficult to imagine for a long time. In the Bras de Grenelle, in front of the Statue of Liberty on the Île aux Cygnes, a swimming area with a spectacular setting is being created. Those who enter the water here will swim with a view of one of the city’s most famous symbols.
In the east of the capital, visitors will find the largest facility. The Bercy swimming area offers several pools, spacious sunbathing areas, and plenty of space for families, athletes, and sun-seekers. Right in the historic center, a new site between the Pont Louis Philippe and the Pont Marie is tasked with replacing the previous swimming area in the Bras Marie. The three facilities are free and supervised by lifeguards during opening hours.
But not only Paris benefits from this development. The offer also grows along the Marne. The popular swimming areas in Joinville le Pont and Maisons Alfort return after their successful start. Already in previous summers, they attracted numerous visitors who enjoyed the uncommon pleasure of bathing directly in the river. The sunbathing areas, safe accesses, and designated swimming zones create almost a holiday atmosphere at the gates of the capital.
Who would have thought that the Seine could become a paradise for bathing?
For decades, swimming was considered impossible. Pollution, river traffic, and health risks made rivers unsuitable for leisure activities. Many Parisians only knew the Seine as a backdrop for walks or boat rides.
The change began with an ambitious sanitation program. Billions were spent to improve water quality. Old sewer pipes were modernized, faulty connections were repaired, and new storage systems were created to better control pollution in case of heavy rains. The 2024 Olympic Games acted as a catalyst. Suddenly, the water quality of the Seine was in the international spotlight.
But the project is not without challenges. Water quality remains a sensitive issue. After heavy rains, additional loads still reach the rivers. That is why regular checks are carried out. If a limit is exceeded, the authorities temporarily close some bathing areas. For visitors, this means some restrictions, but at the same time guarantees a high level of safety.
That is one of the biggest differences compared to the past. The new bathing areas are not improvised water accesses, but professionally managed facilities with clear safety standards. Visitors receive updated information about the water quality and benefit from constant supervision.
Even more: the project changes people’s relationship with their rivers. The Seine and the Marne no longer serve only as waterways or backdrops for tourist photos. They become places of meeting, leisure, and urban life again.
Isn’t this exactly the type of urban development that many European metropolises are seeking?
Paris thus sends a powerful signal. Almost a century after the ban on bathing, a lost tradition returns for generations of inhabitants. The rivers become part of everyday life again. Children splash on the shore, families spend warm summer days in the sunbathing areas, and office workers enjoy a refreshment in the water after work.
The eight bathing areas along the Seine and Marne therefore symbolize much more than just summer fun. They represent the successful attempt to bring nature and city closer together. What once seemed impossible now feels surprisingly natural. And, honestly: a plunge into the cool water with views of the Paris skyline sounds like a pretty good idea.
