Site Overview

Grube Fischbach is a cave dive site in Flooded Mines & Caverns, Germany, reached from the base town of Saarland. Grube Fischbach is a flooded slate mine in the Saarland with impressive galleries and clear, cold water, dived on guided tours with a drysuit. Its sheer rock chambers make for a dramatic, silent overhead dive. The site reaches a maximum depth of 20 m with an average profile around 12 m and a shallow start near 2 m, which places it firmly in the advanced category and means divers should hold at least an Mine/Cave certification. Conditions are typical of the flooded mine environment: visibility generally runs from 10 to 28 metres, the current is weak, and the water temperature ranges between 8 and 10 degrees Celsius with low surge exposure. The marine community is centred on Signal Crayfish, Common Roach, Common Minnow, Common Rudd, European Eel, Tench, and the full species list is detailed below for divers planning a trip. The combination of tunnel, gallery topography and rock substrate gives Grube Fischbach its distinctive character within the Flooded Mines & Caverns region. Grube Fischbach is a strong representative of why German diving is so highly regarded, blending the geology, history and biodiversity that define the country's underwater exploration. It pairs naturally with the other sites of the Flooded Mines & Caverns region for a varied holiday, and with the right thermal protection and, where relevant, the correct specialist training, it offers a memorable dive for photographers, naturalists and wreck, reef or freshwater enthusiasts alike. As with every German dive, a drysuit and a careful respect for cold-water limits turn a good day into a great one.
