This dive site, Marienschlucht in Bodensee, is an advanced wall dive accessible exclusively by boat due to the closure of the Marienschlucht. The underwater topography features a dramatic wall that drops in steps, reaching a maximum depth of 31 meters for recreational divers, although the formation extends to 40 meters. Divers navigate along the steep rock face, exploring crevices and overhangs characteristic of a deep lake environment.
As a freshwater lake dive site, the marine life observed typically includes various freshwater fish species such as perch, pike, and carp. Freshwater invertebrates like mussels and crabs may also be found clinging to the submerged rock structures. Plant life consists primarily of algae and some aquatic vegetation that thrives in the shallower zones.
The best time to visit for optimal diving conditions is during periods of stable weather, as heavy precipitation can significantly reduce visibility by washing turbidity substances from the adjacent forest into the water. Highlights include the impressive stepped wall itself and the unique experience of deep freshwater wall diving. Divers should be prepared for cold water typical of alpine lakes and potentially challenging visibility. Freedivers can explore the upper sections of the wall down to 15 meters.
