The Seine River in Paris was reopened to public use after 100 years. Swimming areas were created at three different points in the river, which was cleaned for the Paris 2024 Olympics.

The Seine River, one of the symbols of Paris, was reopened to public use after a swimming ban since 1923. While the ban on swimming in the river was imposed on the grounds of health risks due to water pollution, the river's water was specially cleaned before the Paris 2024 Olympics and hosted triathlon, open water swimming and paratriathlon races.

Public swimming areas were created at three different locations on the Seine, near the Eiffel Tower, around Notre Dame Cathedral and in the east of Paris. These areas have changing cabins and showers. It was noted that each area has the capacity to serve approximately 300 people at the same time and will be open to the public free of charge at certain hours until the end of August. The age limit for entering the river is set as 10 or 14 years old depending on the region. It was also reported that lifeguards will be on duty in each area for safety.
