The River Seine in Paris has reopened publicly to swimmers for the first time since 1923 after a century-long ban. The seasonal opening of the Seine for swimming is viewed as a key legacy of the Paris 2024 Olympics, when open water swimmers and triathletes competed in its waters which were specially cleaned for the event.

For the first time in over a century, Parisians and tourists will be able to take a refreshing dip in the River Seine. The CBC's Darius Mahdavi tells us whether that's a good idea.
