Paris has officially reopened its iconic Seine River to public swimming, marking the end of a century long restriction. On July 5, residents gathered along the river’s edge to take their first plunge in decades, a symbolic moment brought to life through years of planning and one of the most ambitious urban clean up operations in Europe. This revival was not just a spontaneous move but the result of extensive investments made in preparation for the 2024 Paris Olympics, where the river was featured as a key venue.
The initiative involved over 1.6 billion US dollars being invested to transform the Seine from a polluted urban waterway into a safe, swimmable space. The funds were used to connect thousands of homes to proper sewage systems, modernise water treatment plants, and build massive rainwater retention basins to manage overflow during storms. These efforts ensured that the water quality reached standards acceptable for both Olympic athletes and the general public.
Currently, three main swimming spots have opened to the public within the city of Paris. The first is near the Eiffel Tower, offering swimmers a once in a lifetime chance to float with one of the world’s most famous monuments in view. The second is close to the Notre Dame Cathedral, a location rich in history and visual charm. The third is located in the eastern part of the city, making it accessible to residents and tourists alike. Each of these sites includes facilities like changing rooms, showers, lifeguards, and beach style furniture for those who prefer to lounge by the riverside.
The swimming season will continue until August 31, with up to 1,000 swimmers allowed each day across the three city sites. A flag system similar to beach safety measures has been introduced. Green flags will signal that the water is safe, while red flags will indicate that swimming is temporarily restricted due to water quality concerns. Daily testing will be conducted to ensure health and safety remain a top priority.
While Paris is at the centre of this project, the initiative has also expanded beyond the capital. Fourteen more designated swimming areas are being developed on both the Seine and the Marne rivers, with two already open on the Marne since June. These areas aim to encourage outdoor recreation and promote environmental awareness in nearby regions as well.
This reopening marks a significant moment for the city. Once labelled unsafe and heavily polluted, the Seine is now reclaiming its place not just as a scenic riverbank walk but as a living, interactive part of Parisian life. It also stands as a model for other cities worldwide that are looking to restore their waterways through sustainable urban planning and infrastructure reform.
For those planning to visit Paris, now is the perfect time to experience the city in a unique way. You can float beside historic bridges, gaze up at centuries old architecture, and enjoy a refreshing swim in a place that once felt impossible to reclaim. It is an unforgettable addition to any itinerary.
