The mountains are also famous for the spectacular Dachstein Caves, a network of caverns up to 1,174 meters deep and among the most impressive in the Eastern Alps.
It's an underground world of ice sculptures, gigantic ice curtains, and huge icicles. Highlights include the Giant Ice Cave (Rieseneishöhle) with its many great caverns and magnificent frozen waterfalls (try to visit during one of its regular underground music concerts), and the Mammoth Cave (Mammuthöhle) consisting of huge pipe-shaped galleries formed by an ancient underground river.
