SWIMMING IN THE SEINE

For years, the ultimate Parisian fantasy—diving into the Seine on a hot summer day in the heart of the city—seemed impossible. But this summer, your dream is closer than ever. Not only can you swim at the beloved Bassin de la Villette, but three more brand-new spots have just opened: Bras Marie, Bras de Grenelle, and Bercy. Let’s get into the details!

Your ultimate swimming in the Seine Map

  1. Bras Marie (4th arrondissement, facing Île Saint‑Louis) – a new 70 × 20 m buoyed zone with full lifeguard coverage.
  2. Grenelle (15th arrondissement) – another brand-new zone offering scenic river views.
  3. Bercy (12th arrondissement) – joining the lineup in 2025, this spot brings swimming closer to the parks of Bercy and the National Library.

💧 Is the Water Really Clean?

Yes—and here’s the scoop: after nearly a century of being off-limits, the Seine has finally become swim-worthy again. Ahead of the Paris 2024 Olympics, the city invested heavily in cleaning up the river:

  • €1.4 billion poured into sewage upgrades and modern water treatment facilities
  • A massive underground rainwater basin near Austerlitz prevents sewer overflows
  • Daily testing for bacteria such as E. coli ensures water safety

If quality dips—especially after heavy rain—swimming in the Seine is temporarily paused. But otherwise, the Seine is now cleaner than it’s been in decades.

You can check the current status on the official Paris city water quality page : https://www.paris.fr/pages/meteo-de-la-seine-quelle-est-la-qualite-de-l-eau-du-fleuve-27467. It’s updated in real-time, so you’ll know whether swimming in the Seine is a go or if a spot is temporarily closed.

🛟 Is It Safe?

Definitely:

  • Each area is monitored by professional lifeguards
  • Boat traffic is halted during open hours
  • Safety signage and changing cabins are provided

Some spots, like Bras Marie, may have stronger currents, so a confident swimmer is best suited for these areas.
