Diving Germany’s Flooded Mines & Caverns | Mühlenbach, Fischbach, Roter Bär

About Flooded Mines & Caverns

Germany’s flooded mines offer a uniquely industrial and historic form of overhead-environment diving, where disused lead, silver and slate mines have filled with clear, cold water to create eerie underwater galleries. Grube Mühlenbach in Saxony-Anhalt and Grube Roter Bär in the Harz are guided mine dives through tunnels and past spectacular stalactites, while Grube Fischbach in the Saarland and Grube Anna near Aachen reveal impressive flooded ore galleries. The Marienglashöhle in Thuringia adds a crystal-grotto of gypsum, its lower levels flooded for guided cave dives. These are advanced, drysuit, often full-overhead sites with strict access and permits, but they reward the well-qualified with an atmosphere found nowhere else in recreational diving — a silent, submerged industrial cathedral.
