Is the water clean at Les Rosaires?
Les Rosaires 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 Côtes-d'Armor. You can park about ~110 m away.
Over the 11 classified seasons on record, 9 have come back Excellent or Good — a track record worth checking each year rather than assuming. If you're timing a visit around water temperature rather than crowds, July–September is the safest bet, with August typically the peak — expect a cooler, calmer sea either side of that stretch. Plérin — the closest town — sits about ~3.4 km from here.
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. Water quality here has been improving: the rating moved from Good to Excellent in 2025. There are 6 places to eat within a kilometre — Le Roz R is the closest, about ~80 m away.
