Is the water clean at Le Barn Hotel Etang Du Moulin de Bretigny Bonnelles?
Le Barn Hotel Etang Du Moulin de Bretigny Bonnelles sits on a stretch of coast classed as a lake bathing site, carrying an official EU Bathing Water rating of Not classified 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 Yvelines. You can park about ~1.2 km away.
Looking to avoid the busiest weeks? The water is typically warmest around August, with the most reliable swimming window running July–September; outside that stretch you'll find a cooler sea but a quieter beach. Le Barn Hotel Etang Du Moulin de Bretigny Bonnelles does not yet have enough classified seasons to describe a long-run trend. Bonnelles — the closest town — sits about ~2.2 km from here.
“Not classified” is one point on a four-step scale — Excellent, Good, Sufficient or Poor — assigned once per year from that season's water samples, not a live reading. It describes how the site performs on average across the season, not the exact water quality this afternoon; for day-to-day sea conditions, see the “Right now” and 7-day outlook panels above.
