In brief
After a ban lasting over 100 years, swimming is permitted in the Seine River, with clean-up efforts resulting in three new swimming sites available to the public, celebrating a vibrant return to nature in the heart of Paris.
The Seine River in Paris has officially reopened for swimming, a significant development after being off-limits to swimmers since 1923 due to pollution and boating activity. On July 5, 2025, three designated swimming areas were launched along the river, providing the public with a clean and safe environment to enjoy aquatic activities.A dive into the Seine near the iconic Île Saint-Louis revealed not only the beauty of ancient Parisian architecture but also a refreshing swimming experience. Local swimmer Martine Laupin, 76, expressed her excitement, remarking, "What a joy. What a joy. This is Paris. Imagine!" The water, described as green and silky, provided an inviting escape for the day’s swimmers, as an orange buoy line marked off the swimming zone amid laughter and joy.In addition to the Seine, two new swimming sites have been unveiled on the nearby Marne River, which runs through the southern Parisian suburbs. This initiative is part of France's commitment to restore the river's health, particularly in anticipation of the 2024 Summer Olympics, where athletes will partake in open-water events in the Seine.Just two hours prior to swimming, water quality tests showed satisfactory results, indicated by a waving green flag at the site. This moment marks a significant recreational milestone for residents and tourists alike, as they embrace the chance to swim in the historic river that has shaped much of Paris's culture and identity.
