Is the water clean at Kermarquer?
Kermarquer sits on a stretch of coast classed as a coastal 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 Côtes-d'Armor. You can park about ~440 m away.
Kermarquer does not yet have enough classified seasons to describe a long-run trend. 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. Lézardrieux — the closest town — sits about ~1.0 km from here.
That “Not classified” 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 4 places to eat within a kilometre — Auberge du Trieux is the closest, about ~840 m away.
