Paris Extends Seine River Swimming Into September After 100,000 Visits

A €1.4 billion cleanup enabled safe, supervised bathing.

Overview

  • Mayor Anne Hidalgo said two of the three Seine bathing sites will remain open beyond August due to strong demand.
  • The site near the Eiffel Tower stays open until September 7, and the Bercy/National Library site runs until September 14 with a final weekend on September 20–21.
  • Roughly 100,000 people used the free, supervised river baths over two months, according to city figures.
  • Health authorities reported no serious illnesses among bathers as water quality was checked frequently and a flag system guided daily operations.
  • Operations continue to pause after heavy rain when quality dips, reflecting the new infrastructure’s limits even as ecological indicators improve in the river.
