Shore entry is simple once registered, but the soft bottom and low visibility reward slow movement and careful buoyancy.
About Heiliger See
Heiliger See is a freshwater park lake in Potsdam's New Garden and a controlled shore dive with a strict daily quota. The route starts over sand and shells, then turns silty below the shallow shelf, so steady trim matters more than speed. Visibility can swing sharply with season and wind, and the site is best treated as a calm, methodical freshwater dive. Expect common fish rather than reef life.

Local Intel For Heiliger See
Community notes to help plan your visit.
Scuba Diving
Suitable as a straightforward freshwater scuba dive with variable visibility and silty conditions below ~3 m.
Freediving
Not a primary freedive site; use it only for short, shallow, calm-water sessions because visibility and silt can deteriorate quickly.
Snorkeling
Short near-shore snorkel sessions are possible, but the site is better for calm observation than for long swims once the water turns murky.
