This dive site, Heiliger See, is a freshwater lake located in Potsdam, Germany, notable for its affiliation with the Prussian Palaces and Gardens Foundation. Access is limited to 10 divers per day, requiring registration via email or phone, though typically uncomplicated. Due to its shallow nature with a maximum depth of 7 meters, navigation underwater is generally straightforward, following the sandy substrate that transitions to sediment around 3 meters deep. There's no complex history of the lake specifically for diving, rather it's appreciated for its accessible nature for local divers.
The lake hosts a diverse array of freshwater fish, including perch, rudd, pike, catfish, and occasional eels, providing interesting encounters for divers. The sandy substrate is also home to various shells. While specific aquatic plant life isn't detailed, the sediment layer from 3 meters likely supports some vegetation, creating a natural habitat for the aquatic inhabitants.
The best time to visit Heiliger See for diving is typically during the warmer months, from late spring to early autumn, when water temperatures are more comfortable. Visibility is variable, ranging from 0.5 to 4 meters depending on the season and recent activity, so divers should be prepared for potentially low visibility conditions. Given its shallow depths and calm environment, it is highly suitable for beginner divers and those looking to practice skills. Freedivers and snorkelers will also find the site accommodating due to its easy shore access and shallow average depth of 3 meters. Remember to register in advance to secure your spot.
