Riviera Radłowska - Radłów is a sheltered freshwater dive lake in a former sand quarry, with easy beach entry and a gentle slope from shore. The marked dive zone adds training platforms, buoyed features, and a sunken boat, so the site works well for simple circuits and repeat descents rather than long exploratory swims. Plan for seasonal visibility, shared use with anglers outside the dive area, and the calmest conditions in the open-water season.
