A few years ago this idea seemed almost like a nostalgic postcard from another era: people swimming in the middle of Paris in the Seine. In the summer of 2026 this image will finally become commonplace. Eight free, supervised beaches along the Seine and Marne will open to the public, marking another step in returning rivers as living spaces.
Particular attention is drawn to three new bathing areas within Paris. They combine leisure, sport and urban life in a way that long seemed impossible. At the Bras de Grenelle, opposite the Statue of Liberty on the Île aux Cygnes, a bathing area with an impressive landscape is being created. Those who dive here swim with a view of one of the city’s most famous landmarks.
On the east of the capital the largest complex awaits visitors. The beach area in the Bercy district offers several pools, spacious sunbathing spots and plenty of room for families, athletes and those who want to work on their tan. In the middle of the historic centre a new site between the Pont Louis-Philippe and Pont Marie bridges will replace the former beach area at Bras Marie. All three complexes are open free of charge and are supervised by lifeguards during operating hours.
However, it is not only Paris that is enjoying this development. Along the Marne the number of offerings is also increasing. The popular beaches at Joinville-le-Pont and Maison-Alfort have returned after a successful launch. Already in past summers they attracted many visitors who enjoyed the rare pleasure of swimming directly in the river. Deck chairs, safe entrances and secluded swimming areas there create a true holiday atmosphere at the capital’s doorstep.
Who would have thought that the Seine would one day become a true bathing paradise?
For many decades swimming was considered impossible. Pollution, boat traffic and health risks made these rivers unsuitable for recreation. Many Parisians knew the Seine only as a backdrop for walks or boat trips.
The turning point came with an ambitious cleanup program. Billions in investment were directed at improving water quality. Old sewer pipes were upgraded, incorrect connections were fixed, and new storage systems were created to better control pollution during heavy rains. The 2024 Olympic Games became an accelerator of progress. Suddenly the Seine’s water quality was in the international spotlight.
However, the project is not without challenges. Water quality remains a delicate issue. After heavy precipitation, additional pollution still enters the rivers. Therefore regular checks are carried out. If permissible levels are exceeded, the authorities temporarily close individual beaches. For visitors this sometimes means certain restrictions, but at the same time it ensures a high level of safety.
This is precisely one of the biggest differences from the past. The new swimming areas are not improvised water entries but professionally equipped complexes with clear safety standards. Visitors receive up-to-date information about water quality and benefit from constant monitoring.
Moreover: the project changes people’s relationship with their rivers. The Seine and the Marne have long since ceased to serve only as transport routes or a backdrop for tourist photos. They are once again becoming places for meetings, leisure, and urban life.
Isn’t this exactly the kind of urban development that many European metropolises strive for?
Paris takes a significant step forward. Almost a century after swimming was banned, a tradition lost to whole generations of residents is returning. The rivers are becoming part of everyday life again. Children splash on the shore, families spend warm summer days on deckchairs, and office workers cool off in the water after work.
Eight beaches along the Seine and the Marne mean much more than just summer fun. They symbolize a successful attempt to more closely connect nature and the city. What once seemed impossible today surprises with how natural it feels. And, honestly, a jump into cool water with a view of the Paris skyline is a very good idea.
