When temperatures start to rise, there's nothing better than taking to the water! But when the sea is far away and lakes are inaccessible in the middle of the urban jungle, you have to find alternatives. We're taking advantage of the gradual reopening of certain bodies of water for swimming in the Ile-de-France region, on the Seine, in the Marne and many others, to take a dip and why not try open-water swimming races?
These multiply during the summer season and stop as soon as the cooler weather returns, so if you consult this guide in summer, it may well be empty, in which case you'll have to wait until next summer arrives! Experienced swimmers and amateurs looking for races where they can discover open-water swimming can compete over distances ranging from just a few hundred meters to almost 10 kilometers for the most athletic, not forgetting triathlons.
There's plenty of opportunity to challenge yourselves, or to take to the water in a more playful setting, in a relaxed atmosphere, without a stopwatch, with unusual races! Buoy and bathtub races await you across the region, as do water festivals and paddle descents, for offbeat water events that let you enjoy the summer without taking yourself too seriously.
Dates and Opening Time
