This dive site, known as Immenstaad - Bunker, explores the remnants of a blown-up torpedo test facility in Lake Constance, Germany. It offers a unique wreck-like experience with metal struts and openings to swim through, resembling an artificial reef structure. Divers can navigate around and through parts of the former facility, experiencing its historical remains firsthand.
The bunker acts as a vibrant habitat, particularly for numerous carp, some reaching significant sizes. These fish thrive by feeding on the small organisms inhabiting the bottom, such as various insect larvae, snails, and worms, indicating a healthy ecosystem for macro life.
The best time to visit this site would likely be during warmer months for better water temperatures and potentially improved visibility. Its shallow depth makes it excellent for both scuba divers and freedivers seeking an accessible and intriguing historical site. Beginners will find the depth manageable, while more experienced divers can enjoy exploring the structural features.
