Mammut Cave

The endless expanse of the Dachstein massif from inside – the giant Mammut Cave is one of the largest karst caves in the world impresses with its size, variety of shapes and spectacular artistic installations – something you would never expect to see beneath the ground in Salzkammergut!

The name Mammut Cave was chosen by explorers due to the astonishing dimensions of the underground spaces and passageways contained within this cave system. At present, more than 70 km of these passageways have been explored – around 1 km of them can be viewed during the guided tours.

You can enjoy the time until your guided tour in the cave starts at the idyllic Schönbergalm. There you can visit the exhibition 'climat change at the Dachstein', explore the kids adventure cave, steam off at Almbodenkick or discover the geology at the experiences trail. 

In winter closed!

The Mammut Cave is always closed in winter. With the start of the summer season, you can once again look forward to exciting guided cave tours. Summer season: 10.05.2025 - 02.11.2025

This exciting tour ...

... awaits you in the Mammut Cave

During 50 minutes tours of the Mammut Caves, visitors gain insight into how the caves developed and the work of the cave researchers. They learn how powerful volumes of water once gushed through the mountain as well as the problems which confronted cave researchers in the ‘Midnight Dome’ during their multi-day expeditions of the inside of the mountain.

In this ‘Kingdom of shadows’, there are no boundaries to the imagination. Here, nature has created its own images from the white mountain milk and brown iron oxide, generating names such as ‘Cave Venus’ and ‘Woman with Hooped Skirt’.

And finally, installations from the Linz University of Art - such as the incidence of light and cave scan projects -  never fail to impress.

Do you know?

The West entrance to the Mammut Cave was used as a cellar for many centuries. Poachers, once numerous in the Inner Salzkammergut area, also used the area to store any game they caught.

In 1910, exploration began of the seemingly endless corridors of the Mammut cave from the western side. On the East side, facing the Ice cave, several ice entrances were identified which were finally linked with the western section in 1914.

The First World War brought a halt to the research activities. After the end of the war, the military built a route through the Mammut cave which was then improved over the decades which followed.

Today, over 70 km of the Mammut cave have been researched. The impressive size of the passageways and the hope of finding one of the longest caves in Europe prompted researchers to choose this name (transl. Mammoth cave).

Over the last few years, artistic installations have made the Mammut cave even more attractive and the Dachstein caves are now impressing visitors with their new look.

Do you know?

The height difference between the highest and lowest point reached during the explorations is no less than 1,199 m. As a result of these figures, the Dachstein Mammut cave has been named the 30th longest cave in the world and 31st deepest.
