Spannagel Cave natural monument - Hintertux

The Spannagel cave system with its numerous natural wonders lies in a marble layer from Hintertux southwards to the Spannagelhaus. The entrance to the cave was discovered in 1919 by Alois Hotter, the then landlord of the Spannagelhaus, and exploration of the cave began around 1960.

In 1964, this unique cave and its surroundings were declared a nature reserve

Thanks to the private initiative of hut tenant Josef Klausner (1974-2003), part of the cave was opened to visitors in the entrance area on July 1, 1994. Guided tours of the unique marble show cave take place all year round
