The “Eisriesenwelt” (the World of the Ice Giants) in the Tennen Mountains in the Austrian state of Salzburg is the largest ice cave in the world. On a distance of over 42 kilometers visitors are presented with a breath-taking natural spectacle that reaches deep into the mountain. Crystal clear ice palaces with monumental ice formations dominate the complex cave system. Even on hot summer days temperatures inside the cave are usually below freezing.
