Is the water clean at Castelbouc?
Castelbouc sits on a stretch of coast classed as a river 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 Lozère. You can park about ~110 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 1 classified seasons on record has come back Excellent or Good. On site you'll find Showers, Toilets, and Restaurant. Montbrun — the closest town — sits about ~3.0 km 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 3 places to eat within a kilometre — Lou Claux is the closest, about ~80 m away.
Frequently asked questions
Can you safely swim at Castelbouc?
Yes. Its official 2025 EU Bathing Water rating is Excellent, the top classification, and 1 of the 1 classified seasons on record have rated Excellent or Good.
How warm is the sea at Castelbouc right now?
That reading, around 27°C, is a placeholder rather than a live measurement, shown only because the marine-weather feed was temporarily unreachable; it updates automatically once the feed returns. That's the reading right off Lozère.
What's the ideal time of year to swim at Castelbouc?
The most reliable stretch for warm water runs through July–September, based on the modeled climatology. That applies to the water around Lozère.
What does the water quality rating actually measure?
The grade comes from a full season of official sampling for intestinal enterococci and E. coli, reported to the European Environment Agency each spring under the EU Bathing Water Directive, which assigns Excellent, Good, Sufficient or Poor. Some countries (Croatia, via IZOR) also publish individual in-season samples ahead of that report; Castelbouc doesn't have that feed yet.
How do you get to Castelbouc?
By car, it's easy — parking is right by the beach. The nearest town is Montbrun, about ~3.0 km away.
