Spannagelhöhle

At 2,531 meters in the Zillertal Alps, the Spannagelhöhle is one of the highest accessible show caves in the Alps, carved through white marble by meltwater over millions of years. The cave system runs 13 kilometers in total, though the guided tour covers the most dramatic section of stalactites, dripstone formations, and underground lakes.
