Is the water clean at Baignade Des Forges de Bonnal?
Baignade Des Forges de Bonnal is a lake bathing site with an official EU Bathing Water rating of Sufficient for the 2025 season — meets the minimum EU standard in the latest annual assessment. 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 Restaurant. There's parking about ~680 m from the beach.
Over the 11 classified seasons on record, 10 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 Good to Sufficient in 2025, so it's especially worth checking the latest local advisories. The nearest town, Bonnal, is about ~500 m away.
That “Sufficient” 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's 1 place to eat near the beach — La Forge de Bonnal, about ~230 m away.
