Dive Site Overview
Stepping into Steinbruch Horka feels like entering a submerged time capsule, a freshwater quarry transformed from its industrial past into a fascinating dive destination. Divers begin their adventure via metal stairs that lead directly to a robust wooden platform, providing a convenient staging area for gear checks and a smooth water entry.
