The most spectacular: the Marie Arm

It's probably an image no one thought they'd ever see again: bathers plunging into the Seine at the foot of the Marais district. Yet, in the summer, the Marie branch of the Seine, between the Pont Marie and the Pont Louis-Philippe, opposite the Île Saint-Louis, welcomes swimmers free of charge in a safe zone, a direct legacy of the Paris 2024 Olympic Games. Accessible to all good swimmers, the site is supervised, equipped with pontoons, showers, and lockers, and offers one of the most beautiful views of the historic heart of Paris.

This revival ends more than a century of prohibition. Until the early 20th century, Parisians regularly swam in the Seine, dressed in heavy striped wool suits and bathing caps. Swimming was gradually restricted before being banned in 1923 due to river pollution and increased navigation. It took more than a hundred years, massive investments in water treatment, and the impetus of the 2024 Olympic Games to revive this tradition.

The most festive: Paris Plages

Since 2002, Paris Plages has transformed the banks of the Seine into a vast urban seaside resort every summer. Initially located on the riverside roads, the event has become one of the rendez-vous A must-see during the Parisian summer, attracting several million visitors each year. Deckchairs, parasols, relaxation areas, sports activities, concerts, workshops, open-air libraries and now swimming in the Seine make up this entirely free summer interlude.

Le Marais Enjoy it to the fullest. Between the lively quays, the lawns perfect for picnics, the strollers along the waterfront, and the new swimming area on the Bras Marie, the neighborhood takes on a holiday atmosphere. Just a stone's throw from Île Saint-Louis, it offers one of the best ways to rediscover Paris in the sunshine, combining heritage, fresh air, and a friendly atmosphere. An invitation to slow down… without leaving the capital.

The most conventional: the swimming pool at the Cour des Lions.
Lions Court swimming pool

Just a few minutes away, the Cour des Lions swimming pool offers a more traditional experience. Behind its unassuming facade lies a 25-meter pool bathed in light thanks to its large glass roof and architecture typical of 1930s municipal facilities. Fashion enthusiasts will also know that Simon Porte Jacquemus presented his very first fashion show here, while still a student, transforming the pool's edge into a catwalk. Its other advantage? An unbeatable price: €3,50 for full-price admission. The only drawback is its opening hours, which are often changed depending on the season and activities, so it's essential to check the schedule before going.

Lions Court Pool
9, rue du Alphonse, 75011 Paris
Monday, Tuesday, Wednesday, Friday and Saturday from 7am to 17pm
Thursday 10 a.m. to 17 p.m.

The most closed one: the Saint-Merri/Marie Marving swimming pool
Saint-Merri/Marie Marvingt Swimming Pool
Finally, residents of the Marais district who are used to this stainless steel pool will have to wait a little longer before returning to the Saint-Merri swimming pool. The facility is closed from July 6, 2026 to August 30, 2026 for a major renovation aimed at modernizing the technical installations, improving energy efficiency, renovating the water treatment systems, and bringing the building up to accessibility standards.

We really like this swimming pool renamed Marie Marvingt, in homage to the resistance fighter and aviation pioneer, who was the first French woman to complete the 12 km crossing of Paris by swimming.

It's a shame, then, that this closure is happening right in the middle of the holiday season and during the predicted heatwaves. On the other hand, one could argue that this is a necessary facelift to allow this neighborhood pool to continue its history for many decades to come.
