Is the water clean at Bassin Balance Langevin?
Bassin Balance Langevin is a river bathing site with an official EU Bathing Water rating of Poor for the 2025 season — below the EU standard; swimming may be discouraged or restricted by local authorities. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated until spring 2027. In addition to that yearly rating, some national authorities — for Croatia, the national environmental authority — publish individual water sample results during the season itself, ahead of the annual report. On site you'll find Fast food. There's parking about ~340 m from the beach.
Over the 11 classified seasons on record, 2 have come back Excellent or Good — a track record worth checking each year rather than assuming. The most reliable swimming window here typically runs from July–September, with the sea usually at its warmest around August. Outside that window the water is cooler and often quieter. Worth noting: the rating slipped from Sufficient to Poor in 2025, so it's especially worth checking the latest local advisories. The nearest town, Saint-Joseph, is about ~2.8 km away.
That “Poor” label comes from a full season of official water sampling, not a single test — it's one step on a four-point scale (Excellent, Good, Sufficient, Poor) reassessed once a year. Today's actual conditions can differ from the seasonal average, so for a live snapshot see the “Right now” and 7-day outlook panels above. There are 3 places to eat within a kilometre — Les Pieds dans l'Eau is the closest, about ~150 m away.
