The Ice Grotto at Stubai Glacier

Under the edge of the Stubai Glacier is a world that few get to see and experience: A marvel of nature which lies 30 meters below the ski runs, the Ice Grotto invites a closer inspection in summer and winter. At an elevation of 3,000 meters, the spectacular ice cave puts off a mystical blue colour caused by a unique crystalline structure that absorbs and reflects light, giving the ice its unique hue. Glowing blue walls of ice, light seeping through cracks and holes… the most intense blue occurs in crevasses and when ice breaks off, or calves, from a glacier's face. The 2-meter wide cave tapers to a tight squeeze at the end no more than 2.5 meters high. Travel underneath the glacier to see a surreal world of blue ice and dancing light, created over hundreds of years. Every year the winter snow adds a layer of ice to the glacier, so inside the cave the ice shows a sort of pattern, similar to trees. And the ice contains many traces of every year’s climate. You’ll be fascinated to learn all about glaciers and their impact on our alpine environment. Warm layered clothing is required and footwear should be sturdy. Appropriate gear is available for rental from Intersport Shop at Eisgrat Top Terminal. The Ice Grotto is readily accessible along an easy trail from Eisgrat Top Terminal.
