Bergwerk Nuttlar is the largest diving mine in Germany. It's an old slate mine where you can dive in an open cavern or deep into the old mine. Underwater you can see remnants of the old mine such as rails, trolleys, old trucks and other mining equipment. Those who penetrate deep into the mine dive through long corridors, large chambers and high quarries as big as cathedrals. You can follow several different routes. Always register in advance with Sauerland Diving School. Paid diving.
