Seine River Reopens for Public Swimming in Paris After Olympic Cleanup

After a century of being off-limits, the Seine River in Paris has made a triumphant return to public swimming. On July 5, the iconic waterway, once plagued by pollution, welcomed swimmers back to its banks for the first time since 1923, following an ambitious cleanup spurred by the 2024 Paris Olympics.

The timing couldn’t be more poetic. With Olympic events like the men’s and women’s triathlon unfolding in its waters, the Seine became a centerpiece of global attention. Though last-minute water safety concerns delayed the men’s race by a day, rigorous testing ultimately gave the green light. Beyond the athletes, the river dazzled during the Opening Ceremony, as nations paraded down its currents in a flotilla of boats, captivating Olympians and visitors alike.

Now, the public can dive in at three designated sites along the river, open daily to over 1,000 swimmers through August 31. Early feedback from those taking the plunge has been overwhelmingly positive. A 24-year-old Brazilian resident of Paris marveled, "I never imagined being in the water close to the Eiffel Tower. It’s really nice, I’m impressed." A 51-year-old swimmer echoed the sentiment, noting the water’s clarity and warmth, with just a touch of natural algae.

Behind this revival is a monumental effort to restore the Seine. Investments poured in to connect thousands of homes to proper sewer systems, upgrade water treatment plants, and build rainwater storage to curb overflow during storms. Daily water quality tests, signaled by green and red flags, ensure safety for swimmers. Beyond Paris, 14 additional swimming spots are being established along the Seine and Marne rivers, with some already open.

This isn’t just a win for recreation—it’s a symbol of what determination and vision can achieve. The Seine, once a cautionary tale of neglect, now flows as a testament to renewal, inviting us all to take a dip in history.
