Discover more about Spannagelhöhle

The Spannagel Cave, near Hintertux in Tyrol, is a captivating natural wonder and the largest marble cave in the Central Alps. Stretching over 12.5 kilometers, this extensive cave system is a testament to the powerful forces of nature that have sculpted its intricate interior. A guided tour takes you through the first 500 meters of the cave, revealing a subterranean world adorned with stunning marble formations, erosion cauldrons and crystal. The cave's story began in 1919 when Alois Hotter, the innkeeper of the Spannagelhaus, discovered its entrance. Originally known as the 'Grausliches Loch' and used as a rubbish pit, its true potential was not realized until the 1960s when exploration and surveying began. In 1964, the cave was designated a natural monument, recognizing its scientific importance. The Spannagel Cave lies within a unique geological setting. The main Alpine ridge of the Zillertal Alps consists largely of granite gneiss, but a layer of marble limestone extends from Hintertux to the Spannagelhaus. This marble vein, formed from Jurassic marine limestone transformed by immense pressure and temperatures, is where the cave system developed. Visitors can explore the cave on guided tours that reveal its fascinating features. Equipped with helmets and protective coats (and rubber boots for skiers), you'll descend into the Main Gallery, where you can witness the erosive power of ancient torrents. The tour continues through corridors with 'portholes', past kettle-shaped washouts, and across a suspension bridge spanning the Dr. Lorenz Shaft. A small cave museum displays special finds from within the cave, providing further insight into its history and formation. For the adventurous, cave trekking tours are available, venturing deeper into the cave's unexplored reaches. These tours require a good level of fitness and surefootedness, as they involve navigating challenging passages, ladders, and even rappelling down shafts.
