Is the water clean at Les Quatre Vaux?
Thinking of swimming at Les Quatre Vaux? The short answer: its official EU Bathing Water rating for 2025 is Poor — below the EU standard; swimming may be discouraged or restricted by local authorities. That rating is set once a year under the EU Bathing Water Directive, from a full season of testing for intestinal enterococci and E. coli reported to the European Environment Agency the following spring, so the 2025 season's grade appeared in spring 2026 and the 2026 season won't be graded 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. Worth noting: the rating slipped from Sufficient to Poor in 2025, so it's especially worth checking the latest local advisories. There's parking about ~240 m from the beach.
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. Over the 11 classified seasons on record, 4 have come back Excellent or Good — a track record worth checking each year rather than assuming. On site you'll find Sandy shore, Showers, and Toilets. The nearest town, Notre-Dame-du-Guildo, is about ~1.7 km away.
Worth remembering: “Poor” isn't a live reading, it's an annual grade — Excellent, Good, Sufficient or Poor — set once a year from that season's water samples and describing the average, not this afternoon's conditions. For what the sea is doing right now, check the “Right now” panel and 7-day outlook above. It sits in Côtes-d'Armor. There's 1 place to eat near the beach — La Cabane, about ~170 m away.
