Is the water clean at L'Etang?
L'Etang sits on a stretch of coast classed as a coastal bathing site, carrying an official EU Bathing Water rating of Excellent for the 2025 season. Under the EU Bathing Water Directive, national authorities test for intestinal enterococci and E. coli through the season and report the results the following spring — the 2025 rating was published in spring 2026, and 2026's won't follow 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. It sits in Loire-Atlantique. There's parking about ~400 m from the beach.
That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. 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. It's been a consistently reliable spot too — the rating has held at Excellent for 11 straight years. The nearest town, La Plaine-sur-Mer, is about ~2.3 km away.
That “Excellent” 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.
