What kind of beach is this?
This beach belongs to a small coastal village. It's usually calmer than a resort or town beach, though a popular village spot can still fill up on the best summer days.
Estimated from OpenStreetMap surroundings data (ODbL).
Is the water clean at Les Montiers?
Les Montiers 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. There's parking about ~1.0 km from the beach.
That rating has been consistent: every one of the 9 classified seasons on record has come back Excellent or Good. 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. The nearest town, Sables-d'Or-les-Pins, is about ~1.1 km away.
“Excellent” 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.

A handful of countries, including Croatia via IZOR, also publish individual in-season samples ahead of that report — Les Montiers doesn't have that feed set up yet.
