Dozens of people arrived early in the morning on Saturday to paddle into the once-polluted water, following a clean-up brought on by last year's Summer Olympics.

First, France cleaned the polluted river so that Olympians could swim there. Now, a year later, it is opening three sites for locals to plunge in.

The iconic river reopened to the public for the first time in a century on Saturday, but was closed for swimming one day later after rainfall.
