Just a few years ago, the idea seemed almost like a nostalgic postcard from another era: people swimming in the heart of Paris in the Seine. In the summer of 2026, this image is now part of everyday life. Eight free and supervised swimming areas along the Seine and Marne open their access to the public and mark a new milestone in reclaiming rivers as places to live.
The main focus is on the three new swimming areas located within Paris city limits. They combine relaxation, sport, and urban life in a way that long seemed inconceivable. At Bras de Grenelle, opposite the Statue of Liberty on the Île aux Cygnes, a swimming area is established with a spectacular setting. Those who enter the water here swim with one of the city’s most famous monuments as a backdrop.
To the east of the capital, the largest facility awaits visitors. The Bercy swimming area offers several swimming pools, large spaces to lie down, and plenty of room for families, athletes, and sun lovers. In the heart of the historic center, a new site located between the Louis-Philippe bridge and the Marie bridge will have the task of replacing the former swimming area at Bras Marie. These three facilities are free of charge and supervised by lifeguards during opening hours.
But Paris is not the only one to benefit from this development. Along the Marne, the offer is also expanding. The popular swimming areas in Joinville-le-Pont and Maisons-Alfort are back after their initial success. During past summers, they have attracted many visitors enjoying the rare pleasure of swimming directly in the river. Lawns to lie down on, secure access points and designated swimming zones almost create a holiday atmosphere at the gates of the capital.
Who would have imagined that the Seine could become a swimming paradise?
For decades, swimming was considered impossible. Pollution, river traffic and health risks made the rivers unfit for recreational activities. For many Parisians, the Seine was only a backdrop for walks or boat rides.
The change began thanks to an ambitious rehabilitation program. Investments of several billion have been dedicated to improving water quality. Old sewer pipes have been modernized, defective connections repaired and new storage systems created to better control pollution during heavy rains. The 2024 Olympic Games acted as an acceleration factor. Suddenly, the water quality of the Seine was thrust into the international spotlight.
However, the project is not without challenges. Water quality remains a sensitive issue. After heavy rains, additional pollution still reaches the waterways. Regular checks are therefore carried out. If a threshold is exceeded, the authorities temporarily close certain bathing areas. For visitors, this sometimes means a restriction, but this procedure ensures a high level of safety.
This is indeed one of the major differences compared to the past. The new bathing areas are not improvised accesses to the water, but professionally supervised facilities that comply with strict safety standards. Visitors have access to updated information on water quality and benefit from constant monitoring.
Even more: the project transforms the residents’ relationship with their rivers. The Seine and the Marne are no longer just transport routes or backdrops for tourist photos. They are becoming places for meeting, relaxation, and urban life again.
Isn’t this exactly the type of urban development that many European metropolises are pursuing?
Paris thus sends a strong message. Almost a century after the swimming ban, a tradition returns that generations of residents had lost. The rivers are once again part of daily life. Children paddle at the water’s edge, families spend summer days on the lawns, and office workers enjoy some coolness at the end of the day.
The eight swimming areas along the Seine and the Marne therefore represent much more than just a summer pastime. They symbolize the success of an attempt to bring nature and the city closer together. What once seemed impossible now appears surprisingly obvious. And honestly: a plunge into the cool water with a view of the Paris skyline—doesn’t that seem like a very good idea?
