When the discoverers entered the cave for the first time, they were astonished by the huge passages. The cave is one of the biggest caves in the Dachstein Mountain. So they chose a name that would express the size of the cave, and they chose the Mammoth, the largest Pleistocene land animal in Europe. The huge size and the mostly horizontal passages made the development rather simple, and so the cave was opened to the public only a year later. Later an artificial entrance tunnel was built, the Neuer Osteingang (new eastern entrance), into the Lahnerhalle. The 800 m long tour through Halle der Vergessenen (Chamber of the Forgotten), a huge tunnel like passage named Paläotraun, to the Mitternachtsdom (Midnight Dome). The tour returns through a different passage named Arkadenkluft (Arcade Gap). Obviously the discoverers were quite creative when they named the cave.

The cave trekking tours in the Mammoth cave are quite interesting. The cave is rather big and so they are suited for beginners. One tour offers a trip into a labyrinth of passages with about one meter diameter which is really fun. Interesting is also a through tour to a second entrance on the other side of the mountain. This entrance is in the middle of the mountainside and much harder to reach on the surface.

In the Dachstein district there are 200 caves of which Mammuthöhle is the largest. The size of the cave passages just have to be seen to be believed, on either side there are banks of mud with distinct layers which have been laid down by water. There are great dome shaped halls, with planes of repousse, and giant keyhole shaped passages 20 m high and 12 m wide.

There are vertical grooves on the walls indicating running water, and there is red-brown staining from the iron mineral deposits. The only formations are the great white sponge deposits called Bergmilch which cover the walls.

The palaeolithic bed of the River Traun, long drained of water forms a gigantic tunnel and leads to the Mitternachtsdom (midnight dome), an enormous chamber over 40 m high which contains a multivisual slides show. It introduces visitors to the dangerous but exciting work of the speleologists (cave explorers).

Three rare species of beetle are found in this cave together with many cave bear bones. The cave is called Mammoth Cave, not because mammoth bones were found here, but because of its large dimensions.
