This dive site, Schulhaus in Steckborn, Switzerland, is a renowned location particularly suitable for beginners due to its shallow maximum depth and calm conditions. Divers will find three fish traps on the right side from the entrance, which serve as permanent retreats for fish and are designated as no-dive zones to preserve marine life. It is notably recognized as a birthplace for perch (Egli), indicating a vibrant ecosystem.
The waters of Steckborn are teeming with various freshwater species. Divers can expect to encounter an abundance of perch (Egli), along with crayfish, impressive carp, elusive catfish, formidable pike, and pikeperch, making it a very fishy and rewarding dive for observing lake biodiversity.
Bottle fillings are available on-site through Divecorner personnel, enhancing convenience. While fish use the traps throughout the year, the warmer months, typically spring through autumn, might offer the most comfortable diving conditions and potentially higher activity levels. This site is ideal for both snorkelers and freedivers given its shallow profile and rich marine life, offering accessible underwater exploration.
