A visit to the Werfen ice caves, which are open daily from May to October, is not to be missed. During the Tertiary era - 65 million years ago - this immense ice cave began to form in the very heart of the mountain overlooking the small village of Werfen.
The presence of the Salzach river is no stranger to the phenomenon: over all this time, erosion has helped the ice to flow, forming immense galleries today.
