Where tremendous glaciers once covered the land, today one of Austria’s most astonishing spectacles of nature awaits amazed visitors. The gorge in Kaprun combines breathtaking beauty with mystical scenery and experiences that leave lasting memories.

Some 14,000 years ago, during the late ice age, a glacier completely covered the valley of Kaprun and gorged its way through the calcareous schist rocks of the Maiskogel and the Bürgkogel mountains. When the glacier melted, it left behind a gorge through which the river Ache of Kaprun ran. The river dug itself 32 metres deep into the ground and left behind strikingly smooth surfaces and natural whirlpools. Visitors move along narrow rock faces across wooden catwalks and numerous other bridges. Make sure not to miss the white water spectacle of Kaprun’s Ache River!
