Is the water clean at Castellaccio?
Castellaccio is a lake bathing site with an official EU Bathing Water rating of Good for the 2025 season — meets the EU bathing-water standard in the latest annual assessment. That annual classification comes from the EU Bathing Water Directive: national authorities test for two indicator bacteria, intestinal enterococci and E. coli, throughout the bathing season, then report the full-season results to the European Environment Agency (EEA) the following spring — the 2025 season's rating was published in spring 2026, and the 2026 season won't be rated 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. On site you'll find Pebble shore, Showers, and Toilets. You can park about ~360 m away.
That rating has been consistent: every one of the 11 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. Villa Lesa — the closest town — sits about ~800 m from here.
That “Good” 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. It's been a consistently reliable spot too — the rating has held at Good for 5 straight years.
Frequently asked questions
Can you safely swim at Castellaccio?
Yes. Its official 2025 EU Bathing Water rating is Good, the second-highest classification, and 11 of the 11 classified seasons on record have rated Excellent or Good. It's also held steady at Good for 5 straight years.
Is the sea warm at Castellaccio today?
That reading, around 26°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.
Which month has the warmest sea at Castellaccio?
July–September is typically the most reliable swimming window, with the sea usually warmest in the second half of summer.
What's behind the water quality rating shown above?
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; Castellaccio doesn't have that feed yet.
How do I get to Castellaccio without a car?
By car, there's parking about ~360 m from the beach. There's a bus stop about ~610 m from the beach. By ferry, the nearest landing is Scalo di Belgirate, about ~2.2 km away. The nearest town is Villa Lesa, about ~800 m away.
