Spring-fed freshwater training lake in Dublin.
Spring-fed freshwater training lake in Dublin.
Dublin Lake is a spring-fed freshwater lake in Dublin that works best as a straightforward training and lake-practice dive rather than a high-density wildlife site. The shoreline drops gradually, so a simple shore entry and out-and-back profile are the usual setup. Expect cool water, visibility that changes with weather and season, and a mostly open bottom with limited plant cover. It is a good fit for buoyancy work, navigation practice, and relaxed freshwater dives.
