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.

Is the water clean at Le Vallion?
Le Vallion 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 Ille-et-Vilaine. You can park about ~150 m 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. That rating has been consistent: every one of the 11 classified seasons on record has come back Excellent or Good. On site you'll find Toilets and Parking. Saint-Jouan-des-Guérets — the closest town — sits about ~900 m from here.
“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. There are 2 places to eat within a kilometre — Auberge du Clos des Vignes is the closest, about ~610 m away.
Frequently asked questions
Is Le Vallion a safe beach for swimming?
Generally, yes. Le Vallion's 2025 EU Bathing Water rating is Excellent — the highest tier — backed by 11 of 11 classified seasons rated Excellent or Good. It's also held steady at Excellent for 11 straight years.
Is the sea warm at Le Vallion today?
The panel above shows a sample value of around 23°C. This is placeholder data shown because a live marine-weather feed wasn't reachable — it will be replaced automatically once the feed is available. That's the reading right off Ille-et-Vilaine.
What's the ideal time of year to swim at Le Vallion?
July–September tends to be the sweet spot for swimming here, with sea temperatures usually peaking later in that stretch. That applies to the water around Ille-et-Vilaine.
What's behind the water quality rating shown above?
The annual classification — Excellent, Good, Sufficient or Poor — is built from a full season of official testing for intestinal enterococci and E. coli, reported to the European Environment Agency each spring. Some national authorities (Croatia's IZOR among them) also publish individual samples during the season itself; Le Vallion isn't yet covered by that in-season feed.
Can you drive to Le Vallion?
By car, it's easy — parking is right by the beach. By bus, the nearest stop is Saint-Jouan Stade, about ~610 m away. The nearest town is Saint-Jouan-des-Guérets, about ~900 m away.
